I`m looking to build a 2 storey 4 bed detached house on land that i own. What is the likely build cost if i sub contract most of the work out to average specification.
Next time you are in WH Smith, go and look at Housebuilder & Renovation Magazine. It contains a pretty comprehensive table in the back each month that gives you just this sort of information for various sizes of houses, various types (2-storey, bungalow) and in various parts of the country.
You might even decide to buy the magazine.
It will be in the range £1000 to £1400 per square metre of built structure floor area.
