Do I Need Planning Permission To Build An Extension?

If you’re running out of space, building an extension is much less disruptive than moving house. One stumbling block for many is planning permission – namely the rules of what you can and can’t build.You also need to brush up on the Party Wall Act and the neighbourhood consultation scheme. These pieces of legislation regulate construction activities affecting neighbouring properties to maintain harmonious relationships and avoid legal disputes between property owners.

The below guidance doesn’t apply to listed buildings, which are subject to stricter planning rules. The rules are also different if you live in an area of outstanding natural beauty. Where appropriate, consult with your local planning office.

The Original House Rule

In development guidelines, you’ll often see the term “original house”. This refers to the property as it stood on the 1st of July 1948 or on the date it was built after.

So, if the property already has an extension, you have to factor this into any future development. For example, one planning stipulation is:

You need planning permission if more than half the land around the “original house” is to be covered.

So, in this context, you need to exclude any previous developments from your calculations.

Types Of Planning Permission

There are two main types of planning applications: full planning permission and outline planning permission.

  • Full planning permission is when detailed plans are submitted for all aspects of the development, which provides certainty for construction; it’s suitable for complex projects with defined details.
  • Outline planning permission is preliminary approval based on concepts; detailed designs aren’t required at this stage, and this allows flexibility in design exploration, with reserved matters needing approval later.

Do I Need To Submit A Planning Application For An Extension?

Understanding where you require planning permission for an extension isn’t black and white. Not all extensions are built to the same specification, and the requirements differ depending on whether it’s a side, rear, front, or double- or single-storey extension.

All extensions

You need planning permission if any of the following are applicable to your extension:

  • It’s forward of the front or side of the “original house” that faces onto a highway
  • Over half the land around the “original house” will be covered
  • Materials used aren’t similar to the existing house (except conservatories)
  • The building will be higher than the highest point of the house
  • Eaves and ridge height are higher than the existing house (single- and two-storey)
  • Eaves height is more than three metres (if within two metres of the boundary)
  • The building includes the addition of verandas and balconies.

Side extension

You need planning permission if any of the following are applicable to your side extension:

  • Higher than four metres
  • More than one storey
  • Wider than half the width of the “original house”.

Single-storey rear extension

You need planning permission if any of the following are applicable to your single-storey rear extension:

  • Higher than four metres
  • A semi-detached house that extends beyond the rear of the “original house” by more than six metres
  • A detached house that extends beyond the rear of the “original house” by more than eight metres.

Two-storey rear extension

You need planning permission if any of the following are applicable to your two-storey rear extension:

  • Extends more than three metres beyond the rear of the “original house”
  • Within seven metres of the boundary opposite rear wall
  • Pitch of the roof pitch doesn’t match the existing property
  • Side-facing windows are not obscure-glazed and can open.

Understanding The Party Wall Act

The Party Wall Act 1996 exists to prevent and mitigate disputes between neighbours. The law requires that you give notice to a neighbour if you are:

  • Building near the boundary of a neighbour
  • Working on a wall that separates your property from a neighbour’s.

It’s strongly recommended that you familiarise yourself with the Party Wall Act 1996 here.

The Neighbour Consultation Scheme Explained

If you’re planning to build a large single-storey rear extension, you’ll need to contact your local planning authority through a Prior Approval application.

Important! Your extension is classed as “larger” if it’s between 4–8 metres for a detached house or 3–6 metres for a semi-detached house.

Neighbours can object to your home extension, which can be investigated by your local council.

It allows neighbours to be informed about larger extensions, and it gives them an opportunity to express concerns or object to the development.

Generally, if the extension falls within the permitted guidelines, no action will be taken that results in you needing to apply for planning permission or remove the extension. However, the power rests firmly with the local authority to assess whether the project’s impact on surrounding properties is acceptable.

After the application has been submitted, the determination period lasts for 42 days.

Lawful Development Certificate (LDC)

While your permitted development rights may mean that you can proceed with your extension without planning permission, if you’re concerned about neighbour disputes, you can apply to your local planning authority to obtain a lawful development certificate.

It’s not a legal requirement to obtain one, but it serves as proof that your development is lawful, meaning you can carry out your project with confidence.

The costs to obtain a certificate vary depending on your country:

  • England – £103
  • Scotland – £101
  • Wales – £85

Important! The fee is double if you’re applying in retrospect, that is, for a construction that has already taken place.

If you decide to use your permitted development rights (without needing planning permission), you may jeopardise your project. If your extension deviates from the rules, you risk being fined or forced to demolish the work.

It’s also likely that you’ll need a lawful development certificate at some point, anyway. If you decide to sell your property, in the absence of legal documentation, many buyers will be dubious when purchasing a property that’s been extended.

The 45-Degree Rule Explained

Imagine you’re looking at your floor plans from a bird’s-eye view. Using the midpoint of your neighbour’s nearest window, draw a 45-degree angle away from the window.

If your extension is within this line, it’s deemed acceptable; if it intercepts, then it’s likely that overshadowing will occur (loss of daylight).

The “right to light” gives a landowner the right to receive light through defined apertures in buildings on their own land which neighbouring properties have to take into consideration.

Planning Permission For Extensions – Bottom Line

After assessing the guidelines within, you should have a stronger idea about whether you need planning permission for your extension.

Even if your extension falls under your permitted development rights, and if you proceed to build without planning permission, applying for a lawful development certificate will give you peace of mind before commencing construction.

For specialist projects or if you need any further advice, contact your local planning authority or a planning consultant. If you live in Wales, Planning Aid provides free expert advice.

Planning Permission FAQs

Are building regulations the same in England and Scotland?

Building regulations in England and Wales are set out in the Building Act 1984, and those in Scotland are set out in the Building Act 2003 (Scotland).

So if you’re a developer planning a project spanning multiple locations across the UK, you’ll need to factor in localised regulations. For example, in Scotland, sprinkler installations are mandatory in flatted accommodation, larger multi-occupancy dwellings, and places that deliver care.

What is the difference between building regulations and planning permission?

Building regulations determine the minimum standard for the design and construction of buildings. The regulations are primarily concerned with structural stability, safety, and technical compliance.

Planning permission relates more to the external appearance of the building and ensures any landscaping considerations are in keeping with the local environment to deter inappropriate developments.

What is the 4-year rule for planning permission in the UK?

The four-year rule (which applies to dwellings under class C3) states that local authorities can’t serve enforcement notices for unauthorised developments four years after the commencement of the development.

Despite the rule helping many homeowners gain retrospective planning permission, the four-year rule is set to be phased out in 2023 – thereby closing the loophole.

What is retrospective planning permission?

Retrospective planning permission is sought after building work has already been completed when the necessary permission hasn’t already been obtained. A council may request that you apply for this, for example, if you have constructed a house extension with different materials than what was originally granted.

How To Plan A Construction Project: Your Step-By-Step Project Plan

The principles of planning any construction project are the same, regardless of whether it’s a large or small project. If you’re undertaking a project – maybe you’re planning a self-build, an extension, or commercial premises – there are certain steps to follow to meet your goals on time in full.

So many construction projects fail due to inadequate planning, which leads to scope creep, productivity delays, poor communication, and overspending.

It’s not enough to simply plan. You need to plan properly and follow a set of tried and tested steps in the correct sequence.

The Five Phases Of Construction Planning

Broadly speaking, there are five phases of construction planning. Understanding these will help you know what to expect at each stage to deliver a successful outcome.

  1. Initiation: Project conception and determining the budget, stakeholders, and resources required.
  2. Planning: Defining the work activities and creating a schedule with specific and measurable goals.
  3. Execution: Assigning contractor teams tasks and implementing the project plan.
  4. Monitor: Tracking progress and performance.
  5. Control: Wrapping up the project and evaluating the performance.

Right now, you’re likely at the initiation or planning stage. If you’re further along, and if the execution phase is already underway, it’s a good idea to halt any further site activity until you’ve got a robust plan of action together.

Your Construction Management Plan

Now that you’ve got a general idea of the main phases, it’s time to break down the steps you need to take to bring your conception to life.

1. Define The Project Scope

First, you need to understand what your project is, that is, the project’s purpose, goals, and what you aim to achieve. In short, what’s your vision?

At this stage, you should be able to specify the outcomes, such as the building’s size and boundaries, including any exclusion zones.

After defining what the project is, it’s also worthwhile detailing what the project isn’t. You should have a firm idea about exclusions, such as:

  • Site preparation
  • Decoration and furnishing
  • Landscaping

You should enlist the services of an accredited architect to create your initial design concepts, sketches, and technical plans and drawings.

2. Define Your Project’s Budget

Once you’ve decided where to carry out the construction (for instance, you may have had an offer accepted on some land), it’s time to work out your budget to see if it’s financially viable.

The main costs associated with your project are:

  • Labour
  • Materials
  • Architect services
  • Equipment and tools
  • Land acquisition
  • Loans and financing
  • Construction project management

Fear not! Gone are the days when you have to manually punch an exhaustive list into a spreadsheet and research each cost individually.

Using BuildPartner cost estimation software, you can get a full itemised breakdown of cost options in a matter of minutes, slashing the administration time associated with quoting each project.

You can also choose from a comprehensive list of à la carte-style selections. Products and prices automatically pull through based on the parameters you set.

Best of all? Getting started won’t cost you a penny. Try it out free today by clicking here.

With BuildPartner construction software, you’ll never let a single item go unaccounted for.

3. Get Planning Permission

Okay, so now the ball is rolling, you should seek planning permission for your build.

There are two main types of planning application: full planning permission and outline planning permission.

Outline planning permission is far less detailed than full planning permission. You are essentially asking the local planning authority to agree to the principle of development – with specifics called “reserved matters” to be addressed later.

Whichever type of permission you require, it’s important to get it before proceeding to the next stage. If you’ve had an offer accepted on some land or a property but the planning application is unsuccessful, and if contracts haven’t been exchanged, you can legally pull out of the process, sparing yourself huge expenses.

It usually takes around eight weeks to get planning permission, so you’ll want to submit your application early to avoid delaying completion.

4. Create A Project Schedule

Once you’ve got visibility of your costs, you’ll then want to pull together a construction schedule. Some people swear by construction planning software, and that’s something you’ll want to take a look at if you’re in the habit of planning multiple construction projects.

For someone planning an individual project, a Gantt chart more than suffices. In fact, construction management software always includes one of these as a main feature.

You can find templates for construction Gantt charts on smartsheet. Follow the tips in this video to get started with your first project.

If you’re new to this, a Gantt chart is essentially a visual snapshot of all the tasks that need to be completed by a certain time.

When mapping out your construction activities, you should avoid listing individual tasks and instead think of the Gantt chart as a snapshot of smaller projects.

So instead of listing things like “connect waste pipes”, “plumb in toilet”, and “install bath and shower cubicle”, just write “complete second fix plumbing” which encompasses all the aforementioned.

Keep it simple. Nobody likes a micromanager.

5. Complete A Risk Assessment

While most people immediately think about health and safety when it comes to risk assessments, there are other risks you need to consider that could disrupt your project.

  • Weather conditions such as wind, rain, and heavy snow.
  • Supply chain disruptions and shortages can drive prices up of raw materials.
  • Contractual disputes with subcontractors and disagreements with stakeholders.
  • Natural disasters, mainly flooding and storms in the UK.
  • Financial issues such as cash flow bottlenecks and funding shortages.

There are also other specific risks to your project that you need to be aware of. For instance, environmental protestors blocking a proposed warehouse; or your project may involve bridge or viaduct repair, meaning work has to be carried out during off-peak hours to minimise traffic disruption.

And believe it or not, if a bird’s nest is found on-site, in accordance with the Wildlife and Countryside Act 1981, any works with the potential to damage the nest, egg, or young birds must stop until the young have fledged.

The sample also applies to other protected species, such as bats, otters, adders, and red squirrels.

A full risk assessment should include details of the technical, managerial, environmental, social, and commercial risks.

6. Assign A Project Manager And Assemble Your Team

Getting the right people in the right place at the right time is key to executing your project. Work out who will be accountable for what, and come up with a plan of action to communicate regularly with your project team.

7. Execute The Construction Phase Plan

The goal of the construction project manager is to manage the relationship between the project budget and schedule. That’s easier said than done, of course, but stray from the schedule and you’ll likely wind up throwing money at your problems to make up for lost time.

Delivering a project on time is one thing, but quality control is another. The internet is saturated with new-build horror stories with shoddy brickwork, rising damp, leaks, and countless snags.

Cutting corners will only cause you more problems in the long run.

8. Measure Project Progress And Rework The Plan

Sometimes there are some hidden nasties you can’t foresee during the planning process. One example is the regulatory change that came into effect in June 2022 that requires all new-build homes and commercial buildings in England to be installed with electric vehicle charging points.

For those building an entire estate of new-build homes now, the average cost per installation is between £500 to £1,000.

Other things to be mindful of are:

  • Hidden structural issues
  • Changes in client requirements
  • Safety concerns

How To Make A Construction Plan – Bottom Line

From conceptualisation to execution, a well-structured project management plan guides every aspect of your construction project, ensuring efficient resource allocation, realistic timelines, and smooth coordination among your stakeholders.

If you or your construction manager follow the steps in this guide, you’ll have all your main bases covered before, during, and after your project.

Construction Project Plan FAQs

What is the most common problem in construction projects?

Cost overrun is the top construction industry problem, that is, when a project exceeds its pre-planned budget. A McKinsey study estimates that 98% of big construction projects incur cost overruns of more than 30%.

So, if you’re planning a big project, factor that 30% in on top of your initial budget to see if it’s still viable.

How can I avoid scope creep in my construction project?

The best way to avoid scope creep is to set clear and measurable project objectives that are defined at the outset. If there’s any risk of scope creep, you should clearly communicate this with all stakeholders and discuss contingencies.

Some flexibility is important for minor changes to the plan, but you should know when to say no. Otherwise, the scope of the project will continue to grow arms and legs.

What is the design-bid-build method?

The design-bid-build method involves the completion of three distinct phases in sequence. In essence, the construction process doesn’t start until the design and bid phases are complete, so there’s no overlap between design and construction.

This gives the owner greater control over the design quality and scope. They can review and approve the design before the project is put out for tender (or bidding). There are typically fewer change orders, and there’s much greater cost certainty from the outset.

As for the design-build method (a more traditional method of delivery), the design and construction services are awarded to a single entity that oversees the entire scope of the project. The benefit of this is a shortening of the delivery schedule due to overlapping the design and construction phases.

How To Calculate Building Costs Per Square Metre In Minutes Using BuildPartner

If you’re building a house, or undertaking any construction project, you need to calculate accurate costs per square metre accurately. Let’s face it, most of us have been in those situations where we’ve miscalculated a project and overspent.

You’ve probably seen those enthusiastic first-time investors on Location, Location, Location or Homes Under the Hammer – those who eagerly reveal their unrealistic budgets and are forced to eat their words when revealing their actual spending.

While it’s entertaining to watch (and laugh), it happens to the best of us…

But with building pricing software, you can slash the risk of overspending and get accurate building costs per square metre in just a matter of minutes. Best of all? It costs you nothing to get started, and estimation software is not as technical as you think.

Benefits Of Using Construction Estimation Software

We hate to break it to you, but if your preferred method of calculating building costs is punching a load of numbers into a spreadsheet (or jotting down on the back of a fag packet), you’re missing out and it’s costing you a small fortune.

Using a spreadsheet to work out building costs is the equivalent of core drilling a hole with a 12v combi drill. You wouldn’t even dream of it. And whilst you might get there eventually, you wouldn’t without a fair few expletive-laden rants.

Construction estimation software is like the diamond bit for quoting a project – the tool you need to get the job done properly. Here are the main benefits of using building estimating software:

  • Get a full itemised breakdown of cost options in a matter of minutes, slashing the administration time associated with quoting each project.
  • Unlock cost savings by tweaking the specification to your specific needs. No need to overspend on inessential materials.
  • More options for customers to choose from with a comprehensive list of à la carte-style selections. Products and prices automatically pull through!
  • Greater accuracy and never let a single item go unaccounted for. Ever accidentally missed something off a quote? Nightmare.
  • Transparency for both the contractor and customer, meaning less chance of scope creep.

High: high-spec finishes, e.g., Farrow & Ball, Fine Line, Siemens.

Your choice mainly affects finishings. Remember, you can always change individual elements further down the line in the drop-down style selections of the itemised overview.

3. Choosing The Scope Of Your Build Project

Next, we choose the scope of the project. You can select from one or more of the following options.

Build new: building a new structure and fitting out.

Extend: Adding on to existing structure and fitting out.

Remodel: Changing the layout of a structure or room and fitting out.

Refurbish: Replacing the finishes and fittings in their existing locations.

your first time using BuildPartner construction estimation software, we recommend you select one option to keep things simple.

4. Selecting Shells

Then we select our “shells”, or the structures that will be included in the construction project.

You can select from over 25 options:

Ground floor; pitched roof; stubbed attic; crown roof; middle floor; top floor; brick porch; dormer window; flat roof; garden studio; external storage; ground floor bay window; garage; car port; pillar supported balcony; render porch; timber porch; two-storey house (2, 3, & 4 bed); basement; pricing clarifications; open porch; hip-to-ground-floor gable extension; bungalow.

Select all those that apply and their quantities and click “Next”.

5. Selecting Rooms

On the next page, you can choose which rooms you’re refurbishing. There are over 45 options to choose from, including kitchen, bathroom, wet room, gym, pantry, and lounge.

You can also use the search bar for easy navigation.

Select all that apply and click “Next”. After clicking, our massive database will crawl millions of cost data points for labour and materials before compiling an accurate, itemised quote.

6. Calculating Cost Per Sq Metre

Once your construction project costs have been calculated, you’ll need to enter your floor plans on the “Areas” tab. Our system autosaves any changes, but you can also click “Save and Exit”.

Then head over to the “Schedule” tab to amend the itemised overview of anything and everything from Fixtures and Fittings, Drainage and Pipework, and Internal Doors and Frames.

You might, for example, decide that you need a 16-yard skip instead of the 6-yard skip that’s recommended.

Once your quotation contains all the particulars required for your construction project, simply navigate to the “Cost Per Sq Metre” section to see your costs.

Top Tip! In the “Quotes” tab, you can see three options for quotes based on different specifications: Low Benchmark, Mid Benchmark, and High Benchmark.

These serve as a useful price comparison that you can discuss with customers and amend accordingly by clicking the “Go to individual quoter” icon.

Construction Costs – FAQs

What are the average building costs per sq metre in 2023?

We’ve covered this in greater detail in another article, but here is a summary of the average building cost per m2 in the UK (2023):

What factors affect total house build cost?

When starting, it’s a good idea to familiarise yourself with the entire scope of a construction project to avoid any hidden nasties. While there are too many to list here, we’ve selected the top five which have the biggest impact:

  1. Location. Factors such as local labour rates, availability of construction materials, transportation costs, and local building regulations vary from one place to another.
  2. Size and scope. The size and complexity of the building project directly affect the cost. Larger structures generally require more materials, labour, and time, which ultimately increases the overall cost.
  3. Design and architecture. The architectural design and engineering requirements influence the total cost. Bespoke designs require specialised construction techniques and materials.
  4. Materials. High-quality and specialised materials come at a higher cost. Additionally, the availability of certain materials in the local market also affects their prices.

Labour costs. Labour rates vary based on the location, the skills required, market conditions (supply and demand), and even the time of the year (e.g., peak construction seasons result in higher labour costs).

How can I save money when building a new home?

When it comes to building work, saving money doesn’t mean you have to compromise on your fixtures and fittings or roll up your sleeves and don a hi-vis vest. You’ve got to work smart. Here are our top picks for saving money on a new-build home:

  1. Budget wisely. Whether you’re a commercial contractor or undertaking a self-build project, budgeting software will help you plan and organise your finances. Ditch the spreadsheets.
  2. Negotiate with suppliers. Go out of your comfort zone, and don’t be afraid to negotiate prices with suppliers. It’s common practice for some to artificially inflate their prices in anticipation of this. If you don’t ask, you don’t get.
  3. Obtain multiple bids. Even though it might seem like an unnecessary hassle, and even if you happen to like the first contractor, you should get multiple quotes from different contractors and suppliers. Compare bids carefully, considering both cost and quality.

How Innovation And Technology Are Shaping The Construction Industry.

How Innovation And Technology Are Shaping The Construction Industry.

 

Innovation in the construction industry is moving at an unprecedented rate, but just before you get out your Luddite-inspired placards and wage war on the technological revolution, let’s look at how technology is actually shaping the industry.

It’s perfectly understandable to be concerned about the rise and accessibility of technologies like artificial intelligence and automation.

But with the technologies outlined below, you’ll see there’s more reason to be hopeful than fearful, and if you embrace change, you’ll unlock competitive advantages instead of being left behind.

7 Ways Technology Is Impacting Construction

History tells us that technology accelerates job creation rather than stifles it. This dynamic cycle of “creative destruction” underpins innovation, regardless of the industry or market.

 

In fact, the World Economic Forum estimates that technology will create at least 12 million more jobs than it destroys by 2025.

 

While robots rewiring a house or fixing a leaky toilet are unlikely to become mainstream this century, other construction innovations are gaining popularity across the sector.

1. Advanced Takeoff and Construction Estimation Software

One of the most accessible technologies that is impacting the construction industry is quantity takeoff software. Whilst takeoff software isn’t the first buzzword that usually springs to mind when discussing innovation and tech in the construction industry, its effects are profound.

Using construction estimation software like BuildPartner, construction companies can slash administration time and the associated costs of quoting.

Ever quoted for a project, only to never hear from the prospect again? It can be so frustrating – especially if you’ve spent several hours compiling an itemised proposal.

With construction estimation software, you can generate a quotation in minutes. Best of all, with an intuitive platform like BuildPartner, you don’t need a degree in computing to get familiar with it. It’s an affordable solution for even the smallest contractors, and you can even try it for free.

2. Machine-Learning Algorithms

Machine-learning algorithms (MLAs) harness the power of vast amounts of data to learn and make predictions. The success of MLAs depends on the integrity of the data that is built into these databases and predictive models. 

With robust data, a construction firm can analyse historical project data (schedules, budgets, performance metrics, etc.) to predict potential delays and cost overruns. 

Sophisticated AI supply chain software provided by companies like US-based Intelligence Exchange allows firms to leverage MLAs to access real-time demand insights and generate actionable intelligence.

Armed with better analytics and data, larger firms can optimise resource allocation and reduce waste. Other software-as-a-service (SaaS) providers also harness MLAs, for instance, in construction estimation software.

3. 3D Printing – A Blueprint For Success?

3D printing is presently being used for a host of construction needs. Entire houses have been built using 3D technology, including walls, beams, and facades. As it stands, though, printing houses is neither cheaper, faster, nor more environmentally friendly than traditional building.

Despite the present limitations of 3D printing, printers can create complex architectural designs that traditional construction methods can’t.

Not only that, but a 3D-printed structure is much less wasteful. It’s an additive process, meaning that only the necessary materials are printed, which are often cut by a large 3D printer on site. 

Subtractive manufacturing involves material removal with drilling, grinding, cutting, and boring. For example, creating timber products requires the felling of trees, transportation, sawmilling, and sanding before being distributed to merchants and then to construction sites.

4. The Metaverse – Virtual Reality And Augmented Reality

There are some incredibly exciting developments and breakthroughs in the virtual reality (VR) market. IrisVR is a platform that provides to-scale previews of a construction project before a starting.

Developers and construction managers can walk through a pre-built space in an intuitive environment. This allows them to quickly identify clashes, concerns, and items needing refinement.

It’s also possible to manipulate the previews to evaluate multiple scenarios. With a “digital twin”, or a digital as-built, a virtual representation brings to life real-time data and simulates a concept’s real-world characteristics.

VR is now mature enough that CAD programmes are integrating it as a visual tool, which allows designers and architects to fully create in the virtual realm. Watch this space!

5. Building Information Management (BIM)

BIM is a process that enables all stakeholders to communicate easily in one central place, typically leveraging cloud-based software that’s accessible remotely. 

It serves as a centralised repository for all project-related information, such as 3D models, specifications, quantities, schedules, and cost data. With BIM software, everyone is singing from the same hymn sheet.

For instance, it allows for the inclusion of real-time inventory, providing project managers dynamic predictions as plans change throughout a project.

BIM models can also demonstrate compliance with building regulations and streamline the approval process.

6. Prefabrication

Prefabrication is the act of making building components – such as staircases, wall panels, and modular units – in another location other than the building site. 

Here are some of the benefits of prefabrication:

  • Faster construction. Prefabricated components can be manufactured while site preparation takes place. Once on-site, the assembly process is typically faster than traditional construction.
  • Quality control. Standardised production processes take place in a controlled factory environment, allowing for rigorous quality control measures. 
  • Potential cost savings. While the initial costs of prefabrication are higher, the overall project cost can be lower due to reduced labour.

Even so, prefabrication is undergoing innovation of its own, with the introduction of robotic spider cranes which, using a vacuum gripper, automatically places components at the correct installation position and screws them together.

7. New Sustainable Building Materials

Technology often conjures up connotations of robotics and artificial intelligence. But on the least sexy end of the spectrum are the advanced techniques and processes used to extract and create sustainable building materials. 

Here are some innovative examples which are being used in the construction industry:

  • Bioplastics are derived from renewable resources, including agricultural waste, starch, and vegetable oils. They are moulded into different shapes and used for non-structural components, such as insulation.
  • Mycelium, the root structure of fungi, can be grown and shaped to create lightweight and biodegradable materials suitable for insulation and packaging.
  • By-products such as fly ash from coal-fired power plants can be used as partial replacements for cement in precast concrete mixes, lowering the carbon footprint of concrete products.

When it comes to green construction, it’s a win-win situation for the planet, contractors, and residents.

Bottom Line On Construction Technology

Media hysteria has a lot to answer for in whipping up fears about technological advancements. At some point, you’ll no doubt have stumbled across inflammatory articles such as this Forbes headline: “Will AI Take Your Job? 27% Of Jobs In Wealthy Countries At High Risk”. It’s important to remember that controversial headlines are ultimately what drives newspaper sales and attract higher click-through rates.

 

But on the whole, technology and innovation create jobs, not to mention increase efficiency and productivity. Think about the solar industry; it barely existed a couple of decades ago, but in 2022 alone, solar panel installations increased by 48.5%

As we speak, new industries are being forged and new jobs created. It’s out with the old and in with the new.

Construction Innovation FAQs

What are the four main areas of technology that impact the construction industry?

Broadly, there are four areas in which technology impacts the construction industry.

  1. Building information modelling (BIM). BIM is the digital representation of a building’s design, construction, and operation. It makes collaboration among stakeholders possible through information sharing and providing visibility of the entire project lifecycle. 
  2. Construction automation and robotics. Automation and robotics are revolutionising construction processes. For example, drones are being used for construction site surveys and bricklaying robots are being piloted in certain markets.
  3. Internet of things (IoT). IoT technologies collect and transmit real-time data, allowing project managers to make informed decisions, predict maintenance needs, and optimise resource allocation.
  4. Construction project management software. Construction project management software streamlines project planning, scheduling, budgeting, and communication. 
Will technology replace construction workers?

Technology won’t be replacing highly skilled construction workers any time soon. Strict regulations and health and safety standards are in force, and legal ramifications would need to be addressed before new technologies are deemed safe for mass rollout. 

And while the technology exists to automate repetitive tasks like bricklaying, the technology is in its infancy, inaccessible to most, and operable only in stable environments.

The jobs which are being affected are mainly administrative, where technology is helping streamline project management, scheduling, and cost estimation.

What are five technologies used in sustainable building?

By integrating the following sustainable technologies into building designs, developers and architects can create more cost-effective and environmentally friendly buildings for the future.

  1. Underfloor heating. Radiant floor heating uses the floor surface to distribute heat throughout a building and provide more even temperature distribution.
  2. Rainwater harvesting. Involves the collection, storage, and utilisation of rainwater – generally for non-potable applications such as toilet flushing.
  3. Solar power. Solar photovoltaic (PV) panels harness energy from the sun and convert it into electricity or heat, reducing a building’s reliance on conventional electricity.
  4. Geothermal systems. Geothermal heating, ventilation, and air conditioning (HVAC) systems make use of the earth’s stable underground temperature to heat buildings.

Energy-efficient windows. Energy-efficient windows, such as triple glazing, prevent heat loss, meaning heating systems require less energy to reach target temperatures.

3. Breakdown the Costs

Following the collection of cost information, categorize the costs into different sections such as material costs, labor costs, equipment costs, and administrative costs. This detailed cost breakdown helps in better understanding where the majority of the project funds will be utilized and aids in identifying potential areas for cost savings.

4. Include Contingencies

In spite of the most thorough planning, unexpected expenses can occur during a construction project. To prepare for such situations, it’s essential to include contingencies in your cost plan. A good rule of thumb is to reserve around 10-15% of the total cost for contingencies, although this can vary based on the project’s complexity and risk level.

5. Regularly Review and Update the Cost Plan

As the project progresses, it’s important to continually review and update your cost plan. This involves tracking actual expenditures against your initial estimates, analyzing any discrepancies, and making necessary adjustments. Regular updates ensure your cost plan remains an accurate reflection of the project’s financial status and allows for more proactive budget management.

6. Estimate Profits

Part of your cost plan should also involve estimating the potential profits from the project. This is typically calculated by subtracting the estimated total costs from the total projected revenue. Estimating profits helps assess the project’s financial viability and inform decision-making processes.

7. Leverage BuildPartner’s Automated Cost Plans

To enhance the cost planning process, BuildPartner’s automated cost plan tool can be employed. This software automatically produces a detailed cost plan based on your project specifications and the most recent UK material costs, drastically reducing your workload and minimizing potential human error.
