Build Cost Calculator

The cost of a home/extension depends on its size, the method of construction (brick and block or timber frame) and the build route you follow. The build cost calculator is indicative only and will depend on other factors, such as shape and slope of the site, or quality of the finishes.

NOTE: The indicative figures used in this calculator were last updated in January 2018 and do not include the cost of the site, professional fees, external works or any VAT.
