How much does it cost to build a house?

We asked self build experts to give us an average calculation of different self build house types so you know how much building a house actually costs in 2019.

For a guide on how much it costs to build a new home, take a look at Nottingham-based practice Julian Owen Associates Architects’ build cost table, based on experience rather than the theoretical calculations used by quantity surveyors.

*All sizes are approximate for typical self build houses. Build cost per sqm multiplied by typical floor area.
