duplex construction quote — 189 m², Cameroon

The quote, trade by trade

This is the engine's own breakdown for the duplex model, not a rule of thumb. Each trade is priced from measured quantities — the takeoff deducts openings from the masonry, counts the roof by its real covered area, and bills labour per trade.

Materials, labour and VAT

Of the 70 000 000 FCFA, materials account for 44 400 000 FCFA (63.4%), labour for 14 300 000 FCFA (20.5%) and VAT at 19.25% for 11 300 000 FCFA. If you buy the materials yourself and hire trades directly, the labour line is the part you negotiate; the materials line moves with the market, and you can check it against the published material prices.

What about a different size?

This quote is for 189 m². For a different floor area, do not simply scale it: across the 40 buildings the engine has costed, the rate per m² drops sharply from 552 000 FCFA/m² at 34 m² to about 289 000 FCFA/m² once you pass 150 m² — and then stops falling. Beyond that point the rate is set by what you build, not how big it is: a pool, solar, a third storey or a higher standard of finish each move it more than another 100 m² of floor does.

So a 500 m² villa is neither a 100 m² house times five, nor the same price per m². The honest answer for your own surface is to compute it: the free construction cost calculator takes your floor area, storeys and finish level and returns the same engine's figure in a few seconds — no signup.

The same quote, city by city

City figures apply the regional factors published in the 2026 SangoImmo price index to the same quote — haulage from the port, local labour rates and aggregate supply.

What this quote covers — and what it does not

Covered: the 16 trades in the table above — from earthworks and foundations through to finishes, fittings and fees. Not covered: the land itself, the building permit and survey, connection deposits to the utilities, and anything you add outside the model (a bigger wall, a pool, a borehole). A quote from a contractor should list its exclusions the same way — how to read a construction quote walks through the lines that are usually missing.

Frequently asked questions

How much does it cost to build a duplex of 189 m² in Cameroon?

About 70 000 000 FCFA including tax at a standard finish — 370 000 FCFA/m² of floor area, excluding land. Materials are 44 400 000 FCFA, labour 14 300 000 FCFA and VAT 11 300 000 FCFA.

Can I scale this quote to a different floor area?

Not proportionally. Across the 40 buildings costed by the engine, the rate per m² falls from 552 000 FCFA/m² at 34 m² to about 289 000 FCFA/m² past 150 m², then stops falling — beyond that it is programme (pool, solar, a third storey, finish level) that sets the rate, not size. Use the free calculator to cost your own surface.

Does this quote change from one city to another?

Yes. The same duplex runs about 70 000 000 FCFA in Douala and 72 100 000 FCFA in Ebolowa, mostly through haulage and local labour rates. The city table above lists all 10.

What is NOT in this quote?

Land, the building permit and survey, utility connection deposits, and anything outside the model — a longer boundary wall, a pool, a borehole. Everything else is in the 16 trades listed above.

Can I get this as a real quote document?

Yes. Open the model in the free SangoImmo app, adjust it to your project, and export the quote as a PDF on your own letterhead or the takeoff as a spreadsheet. There is also a free blank quote template if you would rather fill it in yourself.
