How much will it cost to build your home?

The famous Build Cost Calculator from Homebuilding & Renovating is back.  This estimating tool uses figures calculated with help from the Build Cost Information Service. New and updated this building project calculator responds to your location, the size of your house, how you’ll specify it and how you intend to build it. You’ll get an accurate, meaningful estimate of the final cost to build your own home.
