What it would cost to rebuild this house from the ground up, structure only, at today’s rates. Change anything to see the cost update.
Estimated from the 4,176 sqft lot × 53% coverage × 2 storeys. Know the real figure? Type it in.
Floor area: 4,176 sqft of land (URA-recorded lot area) × 53% site coverage = 2,213 sqft per floor, × 2 storeys = 4,426 sqft. 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. URA allows 2 or 3 storeys in Landed Housing Areas (2 in Good Class Bungalow Areas) and 3 outside them; an attic or basement would add floor area and is not counted.
Cost rate: S$348–399 psf for this house type (3Q2025 survey). Build spec picks a point in that range.
