Benchmark scope: The published rates used here are historical 2025 planning references, not live 2026 quotations. Integrum’s methodology includes professional charges, statutory fees and risk allowances. Confirm inclusions before adding separate costs. A construction-only allowance needs a construction-only estimate; a QS should reconcile the scope for your project.
Building a house in Mombasa can cost slightly more than many homeowners expect.
For preliminary planning, a standard residential house in Mombasa may cost roughly:
KSh 59,000–66,000 per square metre
The final figure depends on your house type, size, finishes, exact location, site conditions and the materials you choose.
For a national overview, see our guide to construction cost per square metre in Kenya.
Current construction cost per square metre in Mombasa
Published 2025 Coast-region benchmarks provide a useful guide:
| Building type | Approximate cost per m² |
|---|---|
| Standard bungalow | KSh 58,590 |
| Middle-class maisonette | KSh 65,180 |
| Luxury bungalow | KSh 72,550 |
| Luxury maisonette | KSh 83,760 |
| Standard low-rise apartments | KSh 58,730 |
These are regional planning benchmarks rather than guaranteed contractor prices.
Nationally, AAK reported 2025 benchmarks of KSh 54,730/m² for a standard bungalow and KSh 59,868/m² for a middle-class maisonette, showing why regional differences matter.
How much would a house in Mombasa cost?
Using roughly KSh 59,000–66,000 per m²:
| House size | Estimated construction cost |
|---|---|
| 90 m² | KSh 5.31M–5.94M |
| 100 m² | KSh 5.9M–6.6M |
| 120 m² | KSh 7.08M–7.92M |
| 150 m² | KSh 8.85M–9.9M |
| 200 m² | KSh 11.8M–13.2M |
A 150 m² house might therefore require a preliminary budget of approximately KSh 8.9M–9.9M.
Premium designs can cost considerably more.
How much does a 3-bedroom house cost in Mombasa?
A compact three-bedroom bungalow might be around 90–120 m².
Using the Coast benchmark of KSh 58,590 per m²:
- 90 m²: about KSh 5.27M
- 100 m²: about KSh 5.86M
- 120 m²: about KSh 7.03M
A useful early estimate is therefore roughly KSh 5.3M–7M for a relatively standard three-bedroom bungalow.
See Cost of Building a 3-Bedroom House in Kenya for a fuller breakdown.
How much does a maisonette cost in Mombasa?
The current Coast benchmark for a middle-class maisonette is approximately KSh 65,180 per m².
At that rate:
- 160 m²: about KSh 10.43M
- 180 m²: about KSh 11.73M
- 200 m²: about KSh 13.04M
- 220 m²: about KSh 14.34M
A typical four-bedroom maisonette could therefore fall around KSh 10M–14.5M before major premium upgrades or unusual site costs.
See our guide to the cost of building a 4-bedroom maisonette in Kenya.
Why can building at the Coast cost more?
1. Material transport
Some materials may need to travel long distances before reaching the site.
Transport costs can therefore affect delivered material prices.
2. Coastal exposure
Salt-laden air and high humidity can accelerate corrosion and weathering.
This can influence choices around:
- metalwork
- roofing
- exterior finishes
- fixings
- windows
- protective coatings
Using materials suited to coastal conditions may cost more initially but can reduce maintenance problems later.
3. Site conditions
Some coastal sites may involve sandy soils, drainage challenges or a high water table.
That can influence foundation design and site preparation.
See foundation costs in Kenya.
4. Finishes
As elsewhere in Kenya, finishes can dramatically change the final cost.
Premium tiles, imported sanitaryware, large aluminium windows and high-end kitchens can push a standard project into a much higher budget bracket.
See house finishing costs in Kenya.
Is a bungalow cheaper than a maisonette in Mombasa?
On current regional benchmarks, yes on a per-square-metre basis.
A standard bungalow is approximately KSh 58,590/m², while a middle-class maisonette is about KSh 65,180/m².
However, total project cost still depends on size and design.
A 180 m² bungalow may cost more overall than a compact 150 m² maisonette.
Compare our guides to:
Can KSh 5 million build a house in Mombasa?
At approximately KSh 58,590 per m²:
KSh 5M ÷ KSh 58,590 ≈ 85 m²
So KSh 5 million could potentially support a compact standard home, depending on the design, site and scope of the budget.

Can KSh 10 million build a house in Mombasa?
At KSh 58,590 per m²:
KSh 10M ÷ KSh 58,590 ≈ 171 m²
At the maisonette rate of KSh 65,180/m²:
KSh 10M ÷ KSh 65,180 ≈ 153 m²
That gives you considerably more scope, although the actual design still needs to fit the full project budget.

Remember the costs outside the house
Your main construction rate may not include:
- architects and engineers
- quantity surveying
- approvals
- boundary walls
- gate and driveway
- drainage
- water storage
- utility connections
- landscaping
- contingency
Coastal conditions may also make drainage and material specification especially important.
Once your drawings are ready, a Bill of Quantities can provide a more detailed estimate.
Estimate your Mombasa project with MyJenga
Regional averages are useful, but your project has its own design, location and specification.
MyJenga lets you estimate using details such as:
- location
- floor area
- house type
- number of storeys
- finish level
Frequently asked questions
How much does it cost to build per square metre in Mombasa?
Current Coast-region benchmarks suggest approximately KSh 58,590/m² for a standard bungalow and KSh 65,180/m² for a middle-class maisonette.
How much does a 100 m² house cost in Mombasa?
Using current standard rates, roughly KSh 5.9M–6.6M is a useful preliminary range.
How much does a 200 m² maisonette cost?
At KSh 65,180/m², approximately KSh 13.04 million.
Does this include land?
No. These figures relate to construction only. Land acquisition should be budgeted separately.
Final takeaway
For preliminary planning in Mombasa, a standard bungalow currently benchmarks at roughly KSh 59,000 per square metre, while a middle-class maisonette is around KSh 65,000 per square metre.
That puts a 100 m² standard house at roughly KSh 5.9M, while a 200 m² maisonette could cost around KSh 13M before project-specific adjustments.
Use those numbers as an affordability benchmark, then refine the estimate around your exact site, design, finishes and contractor quotations.
