Frequently Asked Questions about New Build

What’s the cost of New Build?

In the UK, homeowners report the average cost to build a new house to be in the region of £300K+. A 2,000 square foot home (which has approximately 3 bedrooms) would therefore cost £150 per square foot. Many factors can influence this cost, such as the materials used or the grade of the property’s interior fit-out. Using this number as a guide, the costs could range between £250K and £350K. A 4,000 square foot home (which has approximately 5 bedrooms) would cost: £500-600K @ £150 per square foot.

How long does it take to build a house?

Construction times normally depend on how big and complex the project is. A big house can easily take up to 16 months to build. However, the complexity and square meterage of the design are not the only aspects that will impact construction times. Difficult weather conditions and design changes can also lead to longer construction times. It is key that you choose the right team of people to take you through the construction stage to obtain the best end result. At Extension Architecture we have years of experience in liaising with builders and contractors.

Will I need an Engineer?

If you are looking to build your dream home you will need structural calculations and an experienced engineer to produce technical drawings. Our engineers have experience of designing structures using steel, concrete, glass, timber and aluminium, they are aware of market conditions and advice on the appropriate design of a particular project.
