How we got the floor area: 3,589 sqft of land x 53% site coverage = 1,902 sqft per floor, x 2 storeys = 3,804 sqft of floor area. Site coverage: URA sets no site coverage limit for semi-detached houses (only setbacks from the road and the side and rear boundaries), so this uses the typical semi-detached house, which covers 53% of its lot. Storeys: we don't hold this plot's URA storey control. URA allows 2 or 3 storeys in Landed Housing Areas (2 in Good Class Bungalow Areas) and 3 outside them, so this assumes 2. URA also allows an attic and a basement, which would add floor area and are not counted.
