How Much Does It Cost To Build A Porch In 2025? A UK Guide

February 28th, 2025

Building a porch is a great way to enhance your home’s kerb appeal, add extra storage, and improve insulation (heat loss through windows and doors accounts for 20–30% of the whole heat loss of house). A porch also improves home security by adding an extra layer of protection.

 

But costs can vary widely depending on size, materials, and whether the structure is enclosed or open. In this guide, we’ll break down the key factors affecting porch costs in the UK, comparing four different types of porches:

 

  • Brick porch – constructed with bricks.
  • Rendered porch – built with blocks and a rendered finish.
  • Timber porch (enclosed) – made primarily from wood.
  • Open porch – without enclosed walls, and offering an external shelter.

 

Here's a breakdown of the costs for different types of porches, so you can determine which option best suits your project.

 

Building A Porch Construction Cost Calculations

 

Our cost comparisons are based on a gross external floor area (GEFA) of 3m². The only exception is the open porch, which is based on a GEFA of 2m2. Since an open porch is primarily an aesthetic shelter, a smaller size better reflects its typical usage.

 

In terms of build specification BuildPartner pricing tool gives you three broad options (which can be revised by item at a later point):

 

  • Low spec is a basic finish; e.g. Leyland, Everest, Wickes.
  • Mid spec is a standard finish; e.g. Dulux, Hamilton, Slim Line.
  • High spec is a high-spec finish; e.g. Farrow & Ball, Fine Line, Siemens.

 

To keep this comparison simple, we have chosen mid spec in all our cost estimations. In addition to this, we have also provided three different benchmarks to show the range you can expect amongst different contractors. These are:

  • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
  • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
  • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

Frequently Asked Questions About Building A Porch

Here are some frequently asked questions about building a porch.

Can a porch prevent heat loss in my home?

Building a porch improves energy efficiency by creating an air buffer that traps cold air before it reaches your main entrance. It also acts as a thermal barrier, providing an additional layer of protection against the elements. 

The most energy-efficient porches are made from brick and timber, which benefit from greater thermal mass to regulate temperature. uPVC is less efficient without high-quality glazing and seals.

Does adding a porch increase security and reduce the risk of burglary?

If you keep your existing front door, the porch effectively provides double security—a potential intruder would have to get past both the porch and your door to gain entry. This added barrier can significantly deter burglars. 

Is a porch good for storage?

A porch is great for storage because it can act as a cloakroom or boot room, providing space for coats, boots, bags, and outdoor gear. No more coats draped over chairs or shoes scattered around the hallway—it's a purposeful space for your outdoor items.

What are the downsides of getting a uPVC porch?

uPVC porches are generally less energy-efficient and can allow more heat to escape. Additionally, while uPVC porches can last 20 to 30 years, they can become brittle, yellow, or fade with age, especially when exposed to harsh weather conditions. They aren’t as visually appealing as natural materials like brick or timber.

How Much Does It Cost To Build A Garage In 2025? A UK Guide

January 25th, 2025

The cost of building a garage continues to be influenced by rising material prices, labour rates, and regional variations across the UK. Whether you’re looking to build a small single garage or a spacious double garage, understanding the costs involved is essential to avoid cost overruns.

 

In this guide, we’ll provide a detailed comparison of four popular garage types: single garage with a flat roof, single garage with a pitched roof, double garage with a flat roof, and double garage with a pitched roof. This guide also includes regional rate comparisons across the UK, along with building costs per square metre.

 

Building A Garage Construction Cost Calculations

 
In our calculations, we applied a consistent methodology across different regions. The cost comparisons assume the garage is an extension to an existing dwelling, not a new detached structure. These cost excludes the installation of appliances and EV chargers.

 

The typical sizes of garages in the UK are:

 

  • Single – 10 x 18 feet (3m × 5.5m, with a gross external area of 16.5m2)
  • Double – 18 x 18 feet (5.5m × 6m, with a gross external area of 33m2)

 

We have used both of these measurements to calculate the costs in this article.

 

In terms of build specification when using our BuildPartner pricing tool, our pricing calculator gives you three broad options (which can be revised by item at a later point):

 

  • Low spec is a basic finish; e.g. Leyland, Everest, Wickes.
  • Standard spec is a standard finish; e.g. Dulux, Hamilton, Slim Line.
  • Premium spec is a high-spec finish; e.g. Farrow & Ball, Fine Line, Siemens.

 

To keep this comparison simple, we have chosen standard spec in all our cost estimations. 

 

In addition to this, we have also provided three different benchmarks to show the range you can expect amongst different contractors. These are:

  • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
  • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
  • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

 

In short, contractor pricing varies due to factors such as expertise, location, and project intricacies.

Frequently Asked Questions About The Cost To Build A Garage

 
Here are answers to common questions about the cost of building a garage.

What additional costs should I budget for when building a garage?

 
When building a garage, consider the costs of adding an electric vehicle (EV) charger, which typically ranges from £800–£1,500. Upgrading or paving the driveway to provide smooth access can cost anywhere between £1,000–£5,000, depending on the materials used. Additionally, if you need to adjust access to a public road, installing a dropped kerb can cost £1,000–£2,500. 

Do I need planning permission to build a garage in the UK?

 
In the UK, garages under 30 square metres often fall under permitted development and require no planning permission if they meet specific criteria (e.g., height limits, no sleeping accommodation).  
 
Boundary rules (e.g., Party Wall Act) may apply if the garage is built close to property lines. Additionally, restrictions for conservation areas or listed properties may require further permissions. Always check with your local planning authority for specific requirements.
 
For more information, see our related article which covers planning permission.
 

Will building a garage affect council tax band?

 
While adding a garage doesn’t automatically increase your council tax, your local council or the VOA  (Valuation Office Agency in England and Wales, or the Scottish Assessors in Scotland) might reassess your property after the addition—although this is extremely rare. 
 

What is the average daily rate for builders in the UK?

 
Builders typically charge £150 to £300 per day, while specialist trades (electricians, plumbers) may charge £200 to £400 per day. Check out our latest article on our blog for more information about the rates of different trades by region.

How Much Does It Cost To Build An Extension In 2025? A UK Guide

January 30th, 2025

Building an extension is an excellent way to increase living space and add value to your home, particularly when the alternative—moving house—is so expensive. However, costs vary significantly depending on factors such as the type of extension, location, materials used, and the complexity of the project. 

In this guide, we break down the average costs of building a ground-floor and double-storey extension to help you understand what to expect when planning your construction project. We provide the average costs by region and also a breakdown of breakdown by project stage and room type.

Building An Extension In The UK

In our calculations, the costs of building an extension are based on the following:

  • The roof of the extension is pitched, not flat.
  • The extension is constructed out of brick/block, not a timber frame.

Also, the rooms in the calculation for the extension comprise:

  • 20m² single-storey rear extension: dining room, utility room, WC.
  • 40m² double-storey rear extension: dining room, utility room, WC, two bedrooms, an en-suite bathroom, storage room, small landing.

Which rooms you choose ultimately affects the overall cost of the extension. For instance, if we were adding a kitchen instead of a dining room, we would need to factor in the cost of fitting a kitchen and the appliances.

Calculations reflect the cost of fitting out the new rooms only. They do not include the remodelling of existing rooms or changes to the layout.

In terms of build specification, our pricing calculator has three options:

  • Low spec is a basic finish; e.g. Leyland, Everest, Wickes.
  • Mid spec is a standard finish; e.g. Dulux, Hamilton, Slim Line.
  • High spec is a high-spec finish; e.g. Farrow & Ball, Fine Line, Siemens.

 
For the purposes of these extensions, we reviewed the costs for standard specification. Then, for each specification, we’ve provided a range of prices to reflect the varying types of contractors:

  • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
  • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
  • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

FAQs About Building An Extension In The UK

Here are some frequently asked questions about building extensions in the UK.

What are the different types of extensions?

Common ground-floor extensions include rear, side, double-storey, and wraparound. A rear extension expands the back, while a side extension adds space to the side of the property. A double-storey extension increases space both upstairs and downstairs, and a wraparound extension combines rear and side extensions for a larger, open-plan space. 

Do I need planning permission for an extension? 

There are many variables to assess to determine if planning permission is needed when building an extension. For example, you need planning permission if your single-storey rear extension is higher than four metres or extends beyond the rear of the “original house” by more than six metres. 

In many cases, extensions fall under permitted development rights. Find out more about planning permission in our guide here.

Do I need a Party Wall Agreement?

If your extension affects a shared wall or boundary with a neighbour, the Party Wall Act 1996 requires you to serve notice and potentially obtain their consent.

How Much Does It Cost To Build A House In 2025? A UK Guide

January 30th, 2025

As the UK grapples with a cost-of-living crisis and a volatile housing market, building a home in 2025 presents significant challenges. Construction costs per square metre are at historic highs, driven by inflation, material shortages, and changing regulations. 

This guide not only explores average costs by region—including East Anglia, London, the Midlands, and more—but also provides a breakdown of expenses by project stage and room type, offering a detailed understanding of where your budget is likely to go.

Building A House In The UK

House-building costs vary significantly depending on many factors. Sources like Checkatrade offer a general estimate of £1,750 to £2,750 per square metre, while Purple Bricks suggests a lower average of £1,200 to £1,500 per square metre. However, these figures lack context regarding specification or regional variations, offering only a basic rule of thumb.

So, in our calculations, we applied a consistent methodology across different regions, focusing on a three-bedroom detached house. The average number of bedrooms in the UK is 2.95, so we rounded it up to 3 in our estimations. The floorplan was based on the average total floor area of a dwelling in the UK, which is 94m2.

Rooms included in this build are three bedrooms, a bathroom, a kitchen, a living room, a dining room, a cloakroom, the hallway and landing, and a dedicated boiler and storage cupboard. 

A garage was excluded from our calculations since only a third of UK homes have one.

In terms of build specification, our pricing calculator has three options:

  • Low spec is a basic finish; e.g. Leyland, Everest, Wickes.
  • Mid spec is a standard finish; e.g. Dulux, Hamilton, Slim Line.
  • High spec is a high-spec finish; e.g. Farrow & Ball, Fine Line, Siemens.

For the purposes of this comparison of build costs per square metre, we have reviewed the costs for all three specifications. 

In addition, for each specification, we’ve provided a range of prices to reflect the varying types of contractors:

  • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
  • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
  • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

FAQs About Housebuilding Costs In The UK

Here are some frequently asked questions about housebuilding costs in the UK.


Will I pay VAT on self-build projects in the UK?

New-build homes are generally zero-rated for VAT. This means that while contractors and suppliers of building materials may charge VAT on their services, you can reclaim it. 

You can reclaim VAT on integral fixtures like kitchens, bathrooms, and heating systems. However, VAT cannot be claimed on professional services, landscaping, driveways, or non-integral items like luxury fittings (e.g., Jacuzzis).

 

Will Labour’s pledge to build 1.5 million homes affect building costs?

Labour’s pledge to build 1.5 million homes by 2029 could have mixed effects on building costs. While an increase in housing supply may help alleviate pressure on the housing market in the long run, it could also lead to a surge in demand for construction materials and skilled trades, pushing up material costs and labour prices, particularly in areas where construction activity is already high.

Notice: BuildPartner Updated Labour Rates

January 25th, 2025

We’ve recently reviewed and updated our average labour rates (bricklayer, plumber, electrician, plasterer, etc.) so that BuildPartner reflects the latest industry trends. As a result, benchmark rates for existing and new projects have automatically updated. 

These changes do not override the default rates that you may have set up when creating your BuildPartner account. You may want to consider changing your own default rates.

For more details on the changes and how to update your default rates, read on below.

Overview Of Changes

When you create a project, on your Dashboard, you’ll notice three columns summarising a breakdown of cost by project area. These three columns represent:

  • Your rates – the rates you set up on account creation.
  • Low – the average regional rates of smaller, less-specialised contractors.
  • High – the average regional rates of larger, specialist contractors.

(On the Quote page, you can also access Mid rates—the rates of medium-sized contractors that offer a balanced mix of cost-effectiveness and specialisation.)

Different rates

Low, Mid, and High rates are determined by our central default prices.

Given that we’ve recently updated our average labour rates per region, it’s important to be aware that these changes (to Low, Mid, and High rates) will automatically update for:

  • Existing projects
  • New projects

“Your rates” will not update automatically, so you may want to consider changing them. For more details on how to do this, read the section below.

How To Amend Your Default Labour Rates

There are two ways to amend your labour rates:

  1. By amending the default rates of a specific project.
  2. By amending the default rates for all projects (existing and new).

1. Set Rates For A Specific Project

If you want to set the default rates for a specific project, open the project in question and head to the Schedule tab. Then, click the GBP icon (£) and select Labour.

You’ll then be presented with a window where you can manually change the Cost/hr or Cost/day (amending one automatically changes the other). You can then apply an additional percentage for overheads and profit (OH&P) which updates the Rate/day field.

When you’ve entered your rates for this specific project, click Save & Exit.

2. Set Default Rates For All Projects (Existing and New)

To set default labour rates for all projects—including existing and newly created projects—hover over your account initials in the upper-right-hand corner of the screen to reveal your account settings. Then, select Labour Rates.

On the page, you can amend the labour rates for all respective trades (bricklayer, plumber, electrician, plasterer, etc.). 

Important! These rates will be applied to all newly created projects and existing projects.

Average Building Costs Per Sq M For 2025 – A UK Guide

January 25th, 2025

When planning a construction project, understanding the average building costs per square metre will help you create a realistic budget and avoid nasty surprises. 

Whether you’re building a home, extending your property, or adding a garage, this guide breaks down the average costs per square metre. 

In addition, this guide not only explores average costs by region—including East Anglia, London, the Midlands, and more—but also provides a breakdown of expenses by project stage and room type.

Building Costs Per Square Metre In The UK

In terms of build specification, our pricing calculator has three options:

  • Low spec is a basic finish; e.g. Leyland, Everest, Wickes.
  • Standard spec is a standard finish; e.g. Dulux, Hamilton, Slim Line.
  • Premium spec is a high-spec finish; e.g. Farrow & Ball, Fine Line, Siemens.

For the purposes of this comparison of build costs per square metre, we have reviewed the costs for standard specification. In addition, for each specification, we’ve provided a range of prices to reflect the varying types of contractors:

  • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
  • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
  • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

How Much Does It Cost To Build A 3-Bedroom House Per Square Metre?

When calculating the cost of building a three-bedroom detached house, we made the following assumptions:

  • The average number of bedrooms in the UK is 2.95, so we rounded up to 3. 
  • The floorplan is based on the average UK dwelling size of 94m2.

The rooms included in are three bedrooms, a bathroom, a kitchen, a living room, a dining room, a cloakroom, the hallway and landing, and a dedicated boiler and storage cupboard. 

Here’s a table showing the average costs of building a 3-bed house for a standard-spec project in the UK:

How Much Does It Cost To Build A Ground-Floor Extension Per Square Metre?

In our calculations, the costs of building an extension are based on the following:

  • The roof of the extension is pitched, not flat.

8 Benefits of Construction Estimation Software

December 04, 2024

Construction estimation software does a host of sophisticated things, like improving accuracy, encouraging collaboration between parties, and slashing admin time. Embracing it can make all the difference in delivering more competitive proposals and winning more bids.

In this article, we’ll explore eight key benefits of using construction estimating software and how it can transform your approach to pricing for your next projects.

1. Improved Accuracy

One of the most valuable aspects of construction estimation software is its ability to produce spookily accurate cost projections. When pricing for a project, it’s easy to fall into common pitfalls such as:

  • Failing to account for certain building materials
  • Using incorrect or outdated pricing for materials
  • Miscalculating or underestimating labour costs.

Generating estimations manually is a process prone to human error and often leads to underestimating or overestimating project costs. Improper planning is one factor contributing to over 69% of construction projects exceeding their budgets.

Estimation software, on the other hand, improves accuracy by ensuring all costs are accounted for and using real-time data. Platforms like BuildPartner also provide localised pricing for different regions across the UK, giving you the most accurate information for labour rates and materials.

2. Time Savings

Another huge benefit of using construction estimating software is the time it give you back in your day. Think about how long it takes you to produce an itemised estimation. Now, consider how much time you spend doing that across the year for multiple bids.

How many days have you lost, or rather, how many days could you gain back if you were to harness the power of construction estimating software?

Platforms like BuildPartner automate the manual tasks involved in creating project estimates. At the outset of project creation, you click through a handful of intuitive screens to select rooms, specifications, and build types.

Within a matter of minutes, you’re ready to submit, and you can sit back and relax while the system does all the heavy lifting for you. The estimating software scours a database of thousands of localised material prices before generating a detailed, accurate quote.

Aside from doing all this in a fraction of the time it would take to do it manually, it also eliminates the stress.

3. Cost Efficiency

Once you’ve generated your project’s pricing, it’s then much easier to navigate the itemised breakdown – which is much more intuitive than navigating dull spreadsheets. 

Estimation software like BuildPartner allows users to easily add, delete, or change materials in the schedule, which is especially convenient when a client changes their mind or when unforeseen circumstances impact a project.

So, if a particular material is surplus to requirements, you can remove it at the click of a button. Or if you need to add a task or material, you can perform a quick search and find the relevant component.

Not only that but for each building material, you’re presented with a plethora of options in a dropdown menu. You can easily change from, say, a pedestal basin to a wall-hung basin or a vanity unit with a basin. Then, you have another dropdown list with variants from different suppliers and manufacturers, like Victoria Plum, Armitage Shanks, and The Bath Store.

Imagine if you had to manually research all the individual prices of these options? It’s all right there at your fingertips. 

4. Effective Decision Making

With such a comprehensive itemised breakdown, you are able to make much more effective decisions on what materials to include and exclude. By centralising all project costs, timelines, and resource requirements in one platform, it becomes easier to evaluate different scenarios.

All of this information, when consolidated in a central place, makes it super easy to prioritise exactly how to allocate a client’s budget so that it aligns with the project’s goal. For example, you could save £500 by switching to a different brand of paint and then allocate those funds toward quality light fittings that will leave a lasting impression.

When using BuildPartner, you can easily toggle the specification between Basic, Standard, and Premium to see the range of different pricing for a project.

5. Real-Time Updates and Live Prices

Sometimes, clients will sit on a quotation for months before awarding a contract, but prices can change in the meantime. The UK economy has faced a few turbulent years of volatile prices of building materials and commodities. Remember when timber prices surged by over 70% back in 2021, in just a matter of a few months?

So, when using construction estimation software like BuildPartner, you can easily refresh a quote to get the latest prices. Upon request, you can also gain access to your version history, so you can compare previous versions of quotes to see the differences.

At the point of quote creation, the software automatically pulls through live prices.

Resource Cost Breakdown

6. Better Collaboration and Transparency

Construction estimation software facilitates collaboration through a centralised platform. It means that internally, team members can easily make adjustments and address queries. This transparency ensures that everyone is on the same page and cut out unnecessary errors.

Speaking of transparency, some contractors appreciate being able to share the details with their clients, particularly those with strict specifications. 

It helps manage expectations by clearly outlining what’s included and excluded in the estimate, ensuring there are no points of contention once the contract is signed. By providing an itemised breakdown, protecting yourself from scope creep and potential disputes.

Clients appreciate this, too, as it gives them greater flexibility to customise pricing with an à la carte-style material schedule.

7. Cloud-Based Access

Using cloud-based construction estimating software gives users the flexibility to work from anywhere and also ensures that entire teams can access the project estimates in real time.

The most common alternative (using spreadsheets) quite often leads to issues with version control, for instance, when multiple team members are working on different versions without realising. There’s also the added risk of introducing errors when manually entering information.

Also, there is a reduced risk of data loss with cloud-based software due to the secure storage and automatic backups that take place behind the scenes.

8. Land More Bids

Who is more likely to win a contract: a contractor submitting a detailed itemised quote or a contractor who submits a basic quote with no context? 

Submitting accurate quotes builds trust with clients. Now, you can either do this meticulously, monotonously, and manually by entering every single line of detail into a spreadsheet, or you can let the software do it for you.

Aside from building trust with clients, estimating software also ensures your pricing is competitive. Without an itemised breakdown, it’s difficult to be competitive because many contractors make broad assumptions of costs and overinflate their price by X% as a buffer – often to their own detriment.

Submitting the best and most accurate price will bring you closer to winning more bids.

Construction Estimating Software Benefits

By embracing construction estimation software, contractors can create more precise estimates, win more bids, and execute projects with confidence. If you’re ready to ditch the spreadsheets and embrace a new way of working, start your free trial with BuildPartner today.

How Much Does A Barn Conversion Cost In The UK? A 2024 Guide

November 10, 2024

Barn conversions are rising in popularity in the UK, driven by the favourable planning rules and a growing demand for sustainable, character-rich properties for both the residential and holiday rental markets. But how much does it cost to convert a barn? And what is the cost per square metre?

In this article, we cover the costs of barn conversions for a single-storey and a double-storey conversion. We also bring you up to speed on UK planning rules and the differences between classifications of barn conversions in the UK.

Start your free trial with BuildPartner today to get the most accurate estimate of converting a barn based on your own dimensions and specifications.

Barn Conversion Cost Considerations

The costs in this guide assume that the barn conversions do not require new roofs or walls.

Since barn conversions vary in size and there is very limited data on the average size, we based our calculations on a ballpark figure of 80m2 of floor space per storey (160m2 for a double-storey conversion).

  • The double-storey barn conversion comprises four bedrooms, one en-suite, a bathroom, a WC, a kitchen, a living room, and a cloakroom.
  • The single-storey barn conversion comprises three bedrooms, a bathroom, a WC, a kitchen, and a living room.

We also provide a breakdown per square metre so you can work out the costs for your project – if you happen to know the dimensions.

In the cost breakdown provided later, you’ll notice a disproportionate amount of the cost is attributed to foundations and substructure. The main reason for this is that most barns have shallow foundations, which are unsuitable for modern residential standards. 

Therefore, underpinning – the technique that stabilises existing foundations – accounts for a significant part of the cost. 


Build Specifications and Supplier Benchmarks 

In terms of build specification, our BuildPartner pricing tool gives you three options (which can be revised by item at a later point):

 

  • Basic spec is a basic finish; e.g. Leyland, Everest, Wickes.
  • Standard spec is a standard finish; e.g. Dulux, Hamilton, Slim Line.
  • Premium spec is a high-spec finish; e.g. Farrow & Ball, Fine Line, Siemens.

 

For this particular cost breakdown, we have selected standard spec. In addition, for each specification, we’ve provided a range of prices to reflect the varying types of contractors:

  • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
  • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
  • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

Do I need planning permission to convert a barn?

In most cases, you don’t need to submit a full planning application to convert a barn, but it’s a good idea to obtain something called a lawful development certificate.

Despite the name, it’s actually not a legal requirement, but it does protect you in the event of planning policies change. Without one, if your conversion is later deemed to be unlawful, this could result in fines or, worse, the demolition of your project.

To get started, you need to submit your designs by giving “prior notification” to your local authority. They’ll review your designs to ensure you’re within your permitted development rights and a host of other factors such as transport, noise, and flood risk.

It can take anywhere between two to three months to gain approval.

If you plan on extending your barn, however, you will need to apply for planning permission.

Barn Conversion Classifications – UK

In the UK, barn conversions have three main classifications (Q, R, and S). Here’s what each covers:

Class Q – Agricultural to Residential

Class Q allows the conversion of agricultural buildings, such as barns, into residential homes without full planning permission. 

To meet the criteria for Class Q, the barn must:

  • Have been used solely for agricultural purposes before 20 March 2013.
  • Be no greater than 1,000m2 of floor space.

If a barn conversion falls under Class Q, up to ten separate dwellings (previously five) can be created, providing that the maximum size of a dwelling is no greater than 150 square metres. In addition, structural alterations must not extend beyond the original footprint of the building.

Class R and Class S – Agricultural to Flexible Commercial Use

Class R permits the change of use from agricultural buildings to a range of commercial uses, such as retail, offices, restaurants, hotels, or leisure facilities.

Class S allows the conversion of agricultural buildings into state-funded schools or registered nurseries (education facilities).

To meet the criteria for Class R and S, the barn must:

  • Have been used solely for agricultural purposes before 3 July 2012.
  • Be no greater than 1,000m2 of floor space.

Also, the location must not be within protected areas, such as national parks or areas of outstanding natural beauty (AONB).

Proposed Legislation Changes

The previous Conservative government proposed plans to relax rules on barn conversions in national parks and AONBs. These were widely condemned by several key figures, including Kevin Bishop, the CEO of Dartmoor National Park Authority, who said:

“The ability to convert any agricultural barn to an open market house would cause untold damage to our landscapes and do nothing to support the provision of affordable housing.”

The new Labour government has yet to comment on these plans.

Average Cost To Convert A Barn In The UK

So, how much does a barn conversion cost in the UK? Based on the two types covered in this article, you can expect that converting a barn to cost on average (when using a mid-benchmark contractor):

  • Single-storey barn – £218,038, or £2,751 per sq metre.
  • Double-storey barn – £289,581, or £1,828 per sq metre. 

Depending on the specifications, the cost of the work for a barn conversion would range between £188,858 and £370,785. 

Please remember that these costs do not include VAT, and there may be other additional costs, such as obtaining planning permission, conducting structural surveys, making unexpected repairs, and completing custom finishes.

How Much Does It Cost To Build A House In Wales? A 2024 Guide

October 30, 2024

House-building activity in Wales has steadily declined over the past 25 years, with average output decreasing by 45% from over 9,200 homes in the 1990s to just 5,110 dwellings during the first four years of the 2020s. In contrast, England has experienced a 15% increase in house-building activity during the same period. Given these challenges, it's more important than ever to plan carefully if you're considering building your own home. 

To help you budget effectively, we’ve calculated the costs of building a home in Wales. In addition, we’ve also included to the cost to build other projects, such as an extension, garage, porch, loft conversion, and bungalow, and we’ve also provided the costs per square metre. 

Building A House In Wales

Our calculations are based on:

  • A total floor area of 94m2, which is the average for a house in the UK.
  • The average number of bedrooms being 2.95 rooms per house, rounded up to 3.

In terms of build specification, our BuildPartner pricing tool gives you three options (which can be revised by item at a later point):

  • Basic spec is a basic finish; e.g. Leyland, Everest, Wickes.
  • Standard spec is a standard finish; e.g. Dulux, Hamilton, Slim Line.
  • Premium spec is a high-spec finish; e.g. Farrow & Ball, Fine Line, Siemens.

The costs associated with the projects in this guide are calculated according to a standard spec. Then, for each specification, we’ve provided a range of prices to reflect the varying types of contractors:

  • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
  • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
  • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

The Average Cost To Build A House In Wales

So, how much does it cost to build a house in Wales? Based on a standard specification for a typical three-bedroom house, you can expect to pay £276,478, not including the price of land. This figure covers construction expenses like materials and labour but does not include the cost of land.

With demand for social housing reaching critical levels in Wales, 11,692 people were living in temporary accommodation as of March 2024, including over 3,700 in B&Bs and hotels. In response, the Welsh government has pledged to deliver 20,000 social homes by mid-2026. However, not all of these will be new builds—some will come from bringing empty homes back into use.

Frequently Asked Questions About House Building In Wales

Here are a few questions that provide extra insight into the cost of building a house in Wales.

What is Self Build Wales? 

Self Build Wales is a scheme that offers loans to help individuals construct their own homes on eligible plots with planning permission. The scheme covers 75% of the cost of the building plot and 100% of the construction expenses. Builders approved by Self Build Wales will be compensated according to the terms of the loan agreement.

What is the average house price in Wales?

As of April 2024, the average house price in Wales is £236,369, according to the Principality Building Society. However, this marks a 2.4% decrease compared to the same period in 2023. 

The largest increase was seen in Bridgend, where prices rose from £224,857 to £250,921—an annual change of 11.6%. Merthyr Tydfil experienced the steepest decline, with prices dropping from £184,083 to £146,322, a decrease of 20.5%
