Single-storey or two-storey (G+1) house in Cameroon?
At comparable living area, the single-storey costs around 281 000 FCFA/m² and the two-storey (G+1) around 284 000 FCFA/m²: going up costs more per m² (stairs, slab, ring beams) but halves the footprint — decisive on a narrow or expensive plot.
In short
On a large, cheap plot the single-storey is simpler and cheaper per m². On a narrow or expensive urban plot, the two-storey makes the land pay and frees outdoor space, despite a structural premium.
Point-by-point comparison
| Criterion | Single-storey (villa) | Two-storey / G+1 (duplex) |
|---|---|---|
| Cost per m² | Lower | Higher (stairs, slab) |
| Footprint (land use) | Large | Small — ideal for tight plots |
| Structural simplicity | Simple | Slab + upper ring beams |
| Foundations / roof per m² | Costly (all at ground) | Shared over 2 levels |
| Privacy (bedrooms upstairs) | All on one level | Bedrooms away from living area |
| Step-free access | Single level, accessible | Stairs required |
| View and ventilation | At ground level | Better upstairs |
Frequently asked questions
- Single or two-storey: which is cheaper in Cameroon?
- At equal area, the single-storey is generally cheaper per m² (≈ 281 000 FCFA/m² for our reference villa) than the two-storey (≈ 284 000 FCFA/m² for the duplex), because the upper floor adds stairs, an intermediate slab and ring beams. The two-storey, though, saves land.
- Why build up if it costs more per m²?
- Because a second floor cuts the footprint: on a narrow or expensive urban plot, it yields more living area while keeping a garden or parking. Foundations and roof are also shared across two levels.
- Is a two-storey stronger than a single-storey?
- Both are sound when well designed. The two-storey simply needs a more elaborate structure (sized slab, columns and ring beams), so careful study and execution.
