Self Build Costs

How much will it cost to build your dream home? We asked the experts at The National Self Build & Renovation Centre for the facts and figures.


Cost will be the main deciding factor when choosing a construction method, but make sure you consider your particular circumstances. How much work do you intend to do yourself, as this will affect how much money you have to spend? How quickly do you want to build? This is particularly relevant if you are in rented accommodation while working on your project. Do you intend to project manage? If so, off-site manufacture could lighten the load. And when are you planning to start your build? Remember winter isn't ideal for masonry work. We've listed the main build options to help you decide which is right for you.

Construction Methods

Brick And Block: £900 to £1,100 per sq metre
This method is used for around 60% of self builds, especially by those who are looking to keep costs down and do some of the work themselves. It's a quick construction method, but work must stop in bad weather and bricks be allowed to dry out after seven courses, so plan carefully.

Timber Frame: £900 to £1,100 per sq metre
This is the second most popular construction method, used by around 30% of self builders. There are a number of suppliers in the UK and the benefits are that it is relatively quick to build on site, and is a sustainable product.

Steel Frame: £1,000 to £1,100 per sq metre
There are few companies currently deal with one-off houses.

Insulated Concrete Formwork: £1,000 to £1,200 per sq metre
Hollow polystyrene blocks filled with concrete. Quick to assemble, and well suited to self-builders.

Structural Insulated Panel System (SIPS): £1,000 to £1,200 per sq metre
Wooden insulated panels are made off site, meaning they're quick to erect. No room for adjustment on site, and access needed for a crane.

Pre-cast Concrete Panels: £1,200 to £1,500 per sq metre (quotes can be much higher)
Best suited to volume house building, as heavy plant is needed which takes up space, and so provides economies of scale.
