Construction calculator for estimation of lot and building envelope square footage
This online calculator measures the square footage of a lot where the side property lines remain parallel with one another. Besides, it can work out the building envelope on the basis of building setbacks.
To make a perfect estimation, the lengths a, b and c should be matched with their location.
Lot area: The total square footage concerning a property.
Floor area: It includes the total square footage of a dwelling. It is calculated to the exterior face of the building envelope, along with 2nd storey covered balconies and trellises that expand in excess of 1.2 metres (m) from the exterior face of the building (covered section only).
Floor Area Ratio (F.A.R.): Floor area ratio is obtained when the total anticipated floor area of all stories and attics of the main building and all accessory buildings is divided with the site area.
Lot coverage: It is the ratio of the total footprint area concerning all structures on a lot to the net lot area, generally stated as a percentage. The footprints of all main and accessory structures, along with garages, carports, covered patios, and roofed porches, should be added up for the purpose of measuring the lot coverage.
