Approximate cost per square meter to build house in the UK?

Answer 1

There is a huge variation, as you might expect. Starter home standard is still around £600 / m2. Fully fledged architect designed cutting edge type jobs will be around £1500 /m2. Sq metres here refers to internal floor area and excludes external walls, garages, outbuildings and external works. Bear in mind that some sites are much more expensive to develop than others - development costs need to be assessed separately to build costs. Also bear in mind that the difference between £600 and £1500 per m2 is largely down to the specifications - i.e. what the client wants to do and how much they want to spend. You should add around 10% to achieve a passive house standard / high ecohomes ratings (yes just 10%!).
