1 â 10 are usually best written as full words (one, two , three etc). 11+ would be written as numbers. Thereâs no strict rule on this: 11-20 may often also be written as words, but 21+ would almost always be put down as numbers. Make sure youâre consistent over this: donât sometimes write twenty but in other places 20.
Lot area is the area of a parcel of land. Floor area is the sum of a buildingâs usable floor area that is constructed. Their relationship is defined by local Zoning Codes, which usually limit the % of lot coverage (also known as building coverage), the Floor to Area Ratio (F.A.R.), the maximum building height, mandatory setbacks from each side of the parcel etc.
The ratio of the Building area divided by the land (site) area. Building area means the floor space of a building when looking down at it from the sky. Depending on the Land Use Zone category it is regulated within 30% - 80%, and a building has to be constructed within the specified maximum BCR ratio in the zone.
