Built for Nigerian sites
9-inch and 6-inch sandcrete blocks, 50 kg cement bags, 6 m iron rods and tipper loads of sand — the way materials are actually bought here.
Real sites lose blocks to breakage and cement to spillage. Allowances are built in, so you order enough the first time.
Quantities come with current Nigerian prices, adjusted for where you are building — not a bare number you still have to price.
Use a calculator for one job, or send everything through the Building Cost Estimator for a full bill of quantities.
The Building Cost Estimator prices a whole bungalow, duplex or block of flats — or upload your own BoQ and get every line priced. See all options on the Bill of Quantities page.
