How Much Does It Cost to Build a House?

The average cost to build a house is £205,000, but the total price can vary enormously. Where you plan to build your house and the size you want are two of the main factors that will alter the cost. For example, a bungalow in the north of England may cost considerably less to build than a large, detached house in London.

Of course, you'll need to purchase some land to build your house on, and you may find it's not just a London location that puts the price up. The more desirable the location, the more you may have to pay. For example, a plot with good views within a National Park or near a popular resort could cost far more than a similar-sized plot elsewhere.

Plus, planning restrictions could require you to modify your design and use materials that fit in with the local area. Groundworks or demolition of old buildings may also be required before you can start. And every project needs a properly drawn up plan, which will cost around £2,000.

Building a new house costs from £1,700 to £3,500 per square metre. The price of building a new home varies so much because there are multiple construction methods and materials you can use. Whether you decide on a traditional brick-built home, a timber frame, or a prefabricated kit, may considerably affect the price you pay. But style, size and location are not the only factors to consider.

Labour costs can vary, depending on the team you use to complete the build. Typically, builders, labourers, roofers, plasterers, and joiners work on the construction, but you'll also need to hire a plumber and electrician to complete the work.

A construction company may have its own team of specialist trades, saving you the time of finding each one. But that also means you can't shop around for the lowest price.

Hiring a project manager for the build can also add an extra expense. But equally, this could help lower some of your other material and labour costs and help the build go more smoothly. On average, you should expect around half of the build costs to be spent on labour.

Additional Costs

Here are the additional costs you may encounter:

Putting Up Fences

Once your new house has been built, and the heavy machinery has gone, you may wish to install new fences around your property.

It's important to check the property boundary and get the fences put up in the right place. Depending on how much fencing you need and the height and style you go for, it may cost £1,000 to £3,000 to install.

Laying a New Lawn

Although your plot is likely to have been levelled, and you'll have a lovely new home on it, it's unlikely you'll have any garden to speak of. The outside space will probably be a mix of earth and hardcore. So, you may wish to lay a new lawn to add some instant greenery.

Although it may take a few years to establish itself properly, it will give you some usable outside space. The cost of laying garden turf does vary, but on average, you'll pay around £15 per m².

Creating a Driveway

Off-street parking at the front or side of a house is a must-have for modern lifestyles. So, installing a driveway should be high on your list of priorities for the outside space.

You may decide on a simple tarmacked or fashionable resin driveway, depending on your budget and preferences. A resin driveway should cost around £40 per m² and a tarmacked driveway around £45 per m².

Adding Electric Garden Gates

If you're going for a high specification home with all the mod cons, then it's worth considering electric gates at the bottom of your driveway.

Although this may cost around £3,000 to install, It will undoubtedly add value, security and convenience.

Installing Central Heating

A new home isn't complete without central heating, but where you are and what services are available in the area may dictate what type you install.

You may need to run a gas supply to the property so you can install a new boiler. Or you may decide to install an oil-fired boiler instead.

Depending on what you install, it could add between £2,000 and £3,500 to your cost.

Fitting Solar Panels

It's worth thinking about futureproofing your new home and boosting its eco-credentials. And one way to do this is by installing solar panels.

Although the initial cost could be from around £2,000, you could save money over time. You'll need to check solar panels are right for your home first, of course, and find the right specialists to install them.

Home Security Systems

Keeping your new home secure is something else you might find important. There are also many alarms and gadgets to choose from, so this additional cost can vary depending on the type of home security you decide is suitable.

However, you should expect to pay around £500 to have a system installed.

Laying Floor Coverings

The interior of your newly built house will need some floor coverings fitting, whether that's floorboards, carpets or tiles. So, you'll need to think about this cost to finish off your interior, ready for moving in.

The price of laying carpet costs from £250 per room and the price of tiling a floor costs from £400 per room.

Installing a New Kitchen

Fitting a new kitchen in your house will be one of the biggest priorities for the interior. The size and quality of materials can have a big effect on how much you pay.

Plus, there are multiple appliances and gadgets to think about too. Installing a new kitchen should cost from £5,000 for a basic model.

Fitting a New Bathroom

Apart from the kitchen, the bathroom is the most important room in the house. And you may have more than one planned for your new home. Family bathrooms and en suite bathrooms will need installing to your suit your needs, taste and budget.

However, you're likely to pay from £5,000 to £10,000 for a new bathroom.

Labour Costs and Timescales

As you might now be aware, labour costs and timescales can vary a lot when you build a new house. On average, labour costs can account for between 35% and 55% of the total build cost.

And the construction time can take anywhere between six and nine months without hold-ups from planning decisions and material or labour shortages.

Obviously, the bigger the house you're building, the longer it will take. However, the method of construction will also affect the amount of time it takes to build your home.

A traditional brick-built home will take longer to build than a modular or timber-framed house.

For example, it can take six months to build the main structure of a brick-built home, whereas a timber-framed house may only take a couple of weeks.

Although you need to factor in manufacturing times for your framework, this could reduce the amount of labour you need to pay for.

And if you're thinking of opting for a modular or timber-framed house, it may be quicker to put up, but you will need to find trades with the right skills and knowledge to construct it.

The same problem may occur if you decide on other types of non-standard design or construction methods and materials.

You may fancy using large glass panels, precast concrete or fibreglass panels, or a steel framework. However, you'll also need to pay for the right expertise to construct these properly and safely. For example, hiring a structural engineer can cost from £400 per week.

The type of labour you hire will affect your labour costs and your build time. A developer or construction company with its own team of contractors will be quicker and easier than hiring individual trades directly as you won't need to find, hire and coordinate each one. However, you may find you pay more for this convenience.

Where you live can also affect the cost of labour. The price you pay for labour is likely to cost more in London than it would in the midlands or the north of England. However, remote places such as the Scottish Highlands may cost more as local builders may not be so readily available.

So, how much might you pay for the different types of labour needed to build a house? A single builder can charge around £200 per day, but it's likely they will use help from labourers too, which can cost from £100 per day.

However, it's not just builders that are involved in constructing and completing a house. Depending on your builder's skills, you will likely need roofers and joiners to complete some of the structural work.

And a scaffolder may also be required. You'll certainly need a carpenter for jobs such as fitting staircases and a plasterer for the walls and ceilings. A specialist company may also fit windows.

Qualified electricians and plumbers will be required at different stages of the build too. These specialist trades may charge higher rates, but you can expect to pay between £120 and £250 for per day.

And finally, there may be hidden labour costs too. You may need site surveys or demolition work to be done before building starts. And connecting your water, gas and electricity to the main supply outside your home needs to be done by the service providers.

Cost Factors of Building a New House

Here are some cost factors below:

Size and Design of Property

The bigger the project, the more you'll spend on materials and labour. New build bungalows or end of terraces will cost much less than a large, five-bedroom detached house.

The bigger the house, the more bricks, windows and roof tiles you'll need. But the bigger the project, the more you're likely to pay out in labour costs too.

The design of your home could affect the cost too. A straightforward single or double-storey structure, built in a simple square, will cost the least to design and build.

A house with a more complex shape or extra architectural details such as overhanging walls or frameless glazing will cost more.

Type of Structure and Materials

As houses can be built in a variety of ways with a range of materials, this can also affect the amount you pay. For example, concrete blocks are cheaper to lay than traditional brick.

The main structure of your new house could be built from brick, block, timber or come in kit form as prefabricated panels or sections.

It's not just the main structure, though. Cladding, roofing materials, windows and other architectural features you incorporate will affect the cost too.

You may decide to use wood cladding for a more natural or aesthetically pleasing exterior. You might want to use natural stone to add traditional character or use large panes of glass for a modern design.

On top of that, the volume and quality of insulating materials you use can make a significant cost difference. But this is just part of the reason why new house prices vary so much.

Location and Access

The other big cost factor for a new house is the location you build it. The region and size of the plot can both affect the price you pay. Cities and other desirable building locations, such as London, Liverpool and Oxford, can cost far more than you'll pay elsewhere.

Where there is less available land and a high demand for housing, you can expect to pay up to ten times more than the national average for a single plot.

But location can affect build costs in other ways too. For example, some areas such as conservation areas or greenfield sites will require your build to fit in with the local landscape or existing houses.

This could involve using more expensive building materials. And getting your designs through the planning process could take several attempts, which will add both time and cost to your build.

You may have a plot on a hillside with great views, but this could cost more in terms of design, surveys, groundwork and structural engineers.

If access to your site is limited, this can also affect the cost. It could reduce the amount of machinery you can use on-site, increasing labour costs. Plus, it could add time on to delivering or removing materials.

It could also increase the cost of connecting your new build to essential services such as water and electricity.

What's Involved in Building a New Home?

Once you've bought your plot of land, drawn up your plans and had planning permission granted, your home is ready to be built. Step-by-step, here's what to expect from the foundations to finish.

The Groundwork

Before any work can start on building your new house, the site needs to be prepared. Depending on the type of plot you're building on, there may be demolition or clearance work required. Plus, access will need to be created for machinery and deliveries to the site.

Before your construction team can start any building work, you or your project manager will need to inform your local authority building inspector that work is about to commence. Pegs and chalk lines will mark out where your house is to be built.

The Foundations

Next, work begins on digging out the foundation trenches, with supports added if necessary. The type of soil or ground that your house will sit on may also dictate how your foundations are constructed. It's likely that your building inspector will want to make an on-site check at this point.

Then, it's time for the footings to go in. These are usually constructed from poured concrete.

However, if the subsoil on your plot isn't stable enough, piling may be needed. These are steel, concrete or wood columns that sit in the ground to take the weight of your structure.

Guides for the foundations are usually marked out by wooden pegs. As part of the foundation work, drainage and ducts will need to be created for your services. Blocks are usually laid as far as the damp proof course. Damp proofing membranes are then put in place. At this point, your building inspector may make another visit to the site.

The Main Structure

Once the foundations are in, the building of the main structure of your new house will start. This may include digging out service trenches and adding ducts, ready for meter boxes and stopcocks to go in later.

Drainage pipework and vents will start to go in. The floor beams will then go in position, and the initial block and brickwork courses will be built, with doorways and window positions worked out.

The walls will continue to be built up to the wall plate, with lintels for windows, doors and fireplaces put in position, along with the first-floor beams. Walls are often built with an inner blockwork wall, insulation, and brick exterior, but this will depend on the type of construction you choose and your budget.

If the design of your house includes gable ends and a chimney, these will also be built during this stage.

If you're planning a self-build timber frame house, this stage of the build will be different. Usually, designed and engineered sections of the framework will be brought to the site and fitted together.

The external cladding, insulation and other membranes are likely to come in prefabricated panels that join together.

External meter boxes and the water supply to the stopcock may be fitted during this stage.

Wall Plate and Roof Trusses

Once the main body of your house has been completed, the wall plate and roof trusses are installed. The wall plate goes on first. This is a wooden frame that sits on top of the inner blockwork of your wall and provides a base for the house's wooden rafters to sit on.

Next, your roof's trusses are fixed in place. This is the triangular-shaped wooden framework that the rafters and beams will be connected to. These usually come ready-made and are lifted into place.

Horizontal beams known as purlins, along with rafters and joists, are then added to make up your roof structure. These are usually all made from wood. If you're having dormer windows, the framework for these will also be constructed.

Roofing

Next, your roofing materials will be added, beginning with the roof felt. This is a breathable yet waterproof sheet covering often made from composite materials.

Wood battens will then be laid across the roof, ready for the tiles to be fixed on. Depending on the style of your house and the area you live, the tiles may be concrete, clay or slate. Ridge tiles, valley tiles and lead flashing will also be fitted to help make it watertight.

Then soffits, fascia boards and barge boards are added to improve the weatherproofing and the look of your new house. These can be made of wood or uPVC material.

Exterior and Interior Fittings

Once the house's main structure is complete, it's time for the first fixtures and fittings to be put in place. Guttering and drainpipes, windows and doors are just some of these features. But it may also include rendering and other decorative parts of the exterior.

At this point, you'll see the inside of the house start to take shape too. Stud partition walls will go up, as will doorways, window boards and a loft hatch. A carpenter or joiner will be needed at this stage to complete some of the interior jobs. Many of these tasks are known as first fix jobs - a term tradespeople use for the parts of house construction up to the plastering stage.

Connecting Services

At this stage, pipework and wiring goes in. So, you're likely to see both a plumber and electrician getting to work on your house. Jobs will include the first stage of installing your hot and cold water supply, as well as the waste pipework. If you're connected to the gas mains, internal gas pipework and a gas meter will be installed.

Your electrician should be starting to wire the house, with cables run to where your lighting points and sockets will be. The electrician will also fit the consumer unit, which you may know as a fuse box. Any security, safety or smart systems such as wired fire alarms or carbon monoxide detectors will also start to be wired in. If you want underfloor heating, this may start to go in too.

At this stage, it's important for the plumber and electrician to be working together on bonding and earthing to make your services safe. Your local building inspector is likely to visit the site at this stage.

Flooring, Plastering and Carpentry

As the services are going in, you can expect the house to be taking its final shape. And you'll start to see the damp proof course and screed flooring going in. Insulation and plasterboard will be fitted where necessary, ready for a skim coat of plaster.

There's more work for the carpenter or joiner at this stage too. A staircase will need to go in unless you're building a single-storey home. And the other interior woodwork, including doors, architraves and skirting boards, will be fitted. The rooms in the house should now start to take shape, and once the plaster has dried, it will be ready for the more decorative stages to commence.

Kitchen and Bathroom Installation

The fitting of a kitchen and bathroom will be the next stage of the build. This may be completed by your team of contractors, a specialist fitter, or yourself with help from tradespeople.

For the bathroom installation, you can expect tiling work and the fitting of your bath, shower, sink and toilet to take place. Plus, smaller jobs such as connecting light fittings, hanging mirrors or cabinets and sealing around baths and showers.

For the kitchen installation, you can expect your cupboards, worktops, and large appliances to be fitted first. Then tiles and other decorative touches to be added.

Interior Decoration and Snagging

Painting and wallpapering walls and fitting carpets and other floor coverings are some of the last jobs you can expect to be completed in your newly built home. This is so that paintwork and carpets aren't damaged by the mess and dust of building work.

Your contractors may complete this work for you, or you may have arranged for your own carpet fitters and decorators to do it. As well as the decoration, there may be smaller jobs to be completed around the house. These can include fitting the plug sockets and light switches and checking for snagging issues around the house.

A snagging list may include small defects that need rectifying before you move in. This can include touching up paintwork, tightening loose fittings and fixing leaky pipes.

It may also be necessary to remove or replace faulty fixtures such as scratched panes of glass or cracked tiles.

Exterior Landscaping

The final part of your build is most likely to be the exterior landscaping. This may be completed by a team of contractors or by a landscape gardener. Depending on what outside space you have available on your plot, it may include installing a driveway, gates and fences. Plus, you may have a patio or decking and turf laid.

The final completion of your house will also need to be approved by the building inspector. If everything is satisfactory, a Completion Certificate will be issued.

Can I Build a New Build Myself?

Unless you're a qualified builder, building a house as a DIY project is not advisable. However, you may wish to take on certain elements yourself. For example, if you've got a good business background and are used to planning and budgeting, you may fancy project managing the build yourself.

Alternatively, you may wish to take on some of the non-structural parts of the build. This could include interior jobs such as fitting skirting boards and doors and painting and tiling.

Certain stages of the build need to be completed to a specific standard to meet building and planning regulations. This may entail manual tasks such as digging trenches and mixing mortar. But you may arrange to work as a labourer for your builder, to help cut time and costs.

However, jobs such as wiring and plumbing should only be completed by qualified trades. Connecting to the main supplies can only be done by the gas, electricity and water service providers in your area. And there are health and safety regulations, such as working at height, to consider too

Managing the project could save you around 10% of the total new build cost, and doing some of the work yourself could save you another 5% to 10%, depending on how much you take on. However, if you work full time on the build, you'll need to factor in a loss of income from your day job.

Building Regulations & Planning Permission for New Builds

All new build developments require planning permission and must meet building regulations.

You will need full planning permission before you can build a house. You may have bought a plot with outline planning permission, but you'll need to get a detailed plan accepted by your local authority before you can start any work.

If your application gets turned down, you will need to alter your plans and resubmit them. Planning decisions can be affected by many factors, including conservation issues, lack of parking, noise, traffic and the design of your house.

It costs £462 to apply for planning permission to build a house. However, this doesn't include an architect's fees or consulting with your local planning office. There may also be surveys needed to check for flood risks or other environmental issues.

And if you need to appeal the planning decision, you will need to pay an extra £2,000 for this process. You should factor this into your new home cost when creating a budget.

Building Regulations will need to be met when building a new house. Before work starts, during the building process and upon completion, a building inspector will visit the site to ensure everything is satisfactory.

The inspector will check the excavation and foundation work at the beginning, then the damp-proof course and drainage trenches. Once the main structure has been built, they will make at least two further visits.

These inspections are needed for the house to meet building regulations and receive a Completion Certificate. Certificates for your electric wiring and boiler installation will also be required. Your house build will also need to comply with structural, fire safety, ventilation and energy efficiency standards.

Benefits of Building a New Home

If you're taking on a self-build project, you'll get to choose the location as well as design the style and layout of your new home. You can add more ecological materials and insulation to make it economical and environmentally friendly.

You will also have a guarantee of the quality of work and materials used. Plus, maintenance costs for new build houses are also lower.

Hiring Contractors to Construct a New Home Checklist

Unless you're already a builder, it's unlikely you'll be building your own house.

So, it's worth taking the time to hire the right tradespeople or contractors for your project. Use this new house checklist before you hire a builder or contractor.

• Not all builders or building companies have experience of building a house from beginning to end. Only shortlist those who have experience of similar house building projects, using techniques and materials like those on your plans.
• Ask to speak to the builder's previous clients. They should be keen to share details of previous successful projects.
• Most companies and trades will be clear and upfront about their qualifications. They may be able to show you a CSCS card or NVQ certificates to prove their competency.
• Look for companies that are members of relevant trade associations, such as the Federation of Master Builders.
• If you're looking for one company to take on all elements of the build, check they have qualified plumbers, registered gas engineers and electricians on their team. Do they have an experienced site or project manager who can coordinate trades, oversee safety and handle problems?
• Ask what insurance and guarantees they have. Do they have public liability insurance, contractor's all-risk insurance and professional indemnity insurance? And can they provide a written, legally binding guarantee for their work?
