How much does it cost to build a house?

The new build costs in this article are correct as of 2019

Many of us dream of building our own home. Instead of buying a property and trying to make it fit what you need, you can start from scratch, and create a tailor-made home that is perfect from the start. We’ve put together this guide to new build house costs so you have some idea of the prices involved before you hire a new home builder.

Cost to build a house

With such an incredibly broad category, it is very difficult to place a simple price on the cost to build a house. There are thousands of factors involved in home building, from the scale of the build, to the design, the materials and the finishing touches. Coming up with a one size fits all price is very difficult. For a very general estimate, it is easiest to think about the cost per square metre. Breaking it down like this, at the lower end of the spectrum, a new build house might cost as little as £1,400 per square metre. At the top end of this range, you may be looking at more like £2,500, or even £3,000 per square metre. A typical, average price to bear in mind is probably around £1,800 per square metre.


Builders costs for a new house

The majority of the costs involved in building a new property will be in its construction. The superstructure (such as the walls, roof beams and external cladding) will take up the bulk of the costs - around 30% of the total build cost. Brick and block is typically the cheapest method of construction - if using timber frame instead, the price can be increased by around 50%. The costs of the foundations and floor structure will usually be the next largest cost, though this is usually fairly static, unless the plot of land you are building on is on a slope or is of unusually poor quality. The cost of the roof will also be a significant proportion of the overall build cost.

The price of the land itself is not included in any of these calculations. Land prices vary widely depending on the size and condition of the plot, whether or not it has any planning permission attached to it, and of course, where in the country it is.

Architects costs for a new house

Architects fees for designing and overseeing a new build house typically come to between 5% and 15% of the overall costs. When setting a budget, remember to keep aside a suitable amount to cover these fees.

There are a number of other fees that will need to be kept in mind.

You will usually need to apply for planning permission, which is currently £462 if it approved at the first opportunity. Fees for building regulation applications and inspections can cost up to £1,000, while there can be other costs for site surveys and structural engineer reports, which can be around £500 each.


Other common costs involve demolition or waste clearance from the site, which can cost several thousand pounds, and landscaping costs.

There are also numerous legal fees and taxes which will vary depending on the value of the land.

Whenever setting a budget for a new build house, it is advised to keep a contingency budget to cover yourself in case of delays and unexpected fees.
