Current house costs are running at between £750 and £800 per m² plus £10,000 per house for drains, paths and so on – plus the cost of the land, of course. That said, you may need to shop around to get these kinds of figures. Potton is very useful at providing a rough guide to figures for different styles of timber-frame house. You can find cost breakdowns for many of its designs on its website (www.potton.co.uk) or by calling to order a brochure (01767 676400).
