Calculating Areas
Prices are based on the external area of your proposed development. The area is calculated by adding together the external areas of each floor.
For NEW BUILDS the area includes each floor of the main house and integral garages. Loft areas should also be included by measuring to the outside of loft walls. Out-buildings and detached garages will be priced separately – see their associated fee bands.
For EXTENSIONS the price includes associated works, i.e. immediately adjacent structural openings
Prices for REFURBISHMENT and other alterations will be given on application.
The Build It estimating service enables you to calculate your self build costs down to the last roof tile!
