The Build Budget Workbook
The ArkitecTRUE workbook for an extension, renovation or new build: from a builder's price per square foot to the whole cost of the project
A builder's price per square foot covers the construction. The project also pays for design and engineering, permits and surveys, the site, the allowances that turn out low, and the changes you make once work has started. The Build Budget Workbook turns those into one number from your own figures. Part 1 reads the quote for what it leaves out, lists the soft costs, prices the site, sizes a contingency, works out the all-in figure (a 400 square foot extension at $250 a square foot came to $333.75 once everything was counted) and orders materials with waste and spares. Part 2 keeps the budget through the build: stage payments tied to finished work with a holdback, a change-order log against the contingency, and a proper close-out. For homeowners planning a build; not architectural, structural, legal or financial advice. With your purchase comes a personalised sheet with your construction figure, contingency at three levels and a stage payment plan.
