A four-bedroom maisonette is a popular choice for Kenyan families looking for more space without requiring the large ground footprint of a four-bedroom bungalow.
But how much does one actually cost to build?
As a preliminary estimate, a standard or middle-class 4-bedroom maisonette in Kenya could cost roughly KSh 10 million to KSh 14 million to construct, depending on its size, location, design and finishes.
A larger or more luxurious maisonette can easily cost KSh 16 million to KSh 20 million or more.
The most important variable is not simply the number of bedrooms. It is the total floor area and specification of the house.
For the broader picture, see our guide to construction cost per square metre in Kenya.
How much does a 4-bedroom maisonette cost in Kenya?
The latest published industry benchmark places a middle-class maisonette at approximately:
KSh 59,868 per square metre
A luxury maisonette benchmark is considerably higher, at approximately:
KSh 97,730 per square metre
That means the size of your proposed house quickly becomes important.
For example:
| Floor area | At KSh 59,868/m² | At KSh 97,730/m² |
|---|---|---|
| 160 m² | KSh 9.58M | KSh 15.64M |
| 180 m² | KSh 10.78M | KSh 17.59M |
| 200 m² | KSh 11.97M | KSh 19.55M |
| 220 m² | KSh 13.17M | KSh 21.50M |
These are planning estimates, not contractor quotations.
A 200 m² middle-class maisonette, for example, works out at roughly:
200 × KSh 59,868 = KSh 11.97 million
That gives you a useful starting point before architectural drawings, detailed costing and actual contractor quotations are available.
What size is a typical 4-bedroom maisonette?
There is no fixed size.
A relatively efficient four-bedroom maisonette might fall around 160–200 m², while a more generous design could exceed 220 m².
The house might include:
- four bedrooms
- several ensuite bathrooms
- living room
- dining area
- kitchen
- pantry
- utility area
- guest WC
- staircase and circulation space
- balconies or terraces
Every additional square metre adds cost.
This is why two four-bedroom maisonettes can differ by several million shillings even when the number of bedrooms is identical.

Can KSh 10 million build a 4-bedroom maisonette?
Potentially — but the house would need to be carefully designed.
At the current middle-class benchmark of approximately KSh 59,868 per m²:
KSh 10M ÷ KSh 59,868 ≈ 167 m²
That suggests a KSh 10 million construction budget could theoretically support a maisonette of roughly 165–170 m² at that benchmark.
But the actual feasibility depends on:
- location
- site conditions
- structural design
- roof design
- number of bathrooms
- windows and glazing
- kitchen specification
- finishes
- external works
- what is included in the contractor’s scope
If KSh 10 million is your fixed budget, our guide to what you can build with KSh 10 million in Kenya will be useful.
Why does a maisonette cost more than a bungalow?
A maisonette usually has greater structural complexity.
Unlike a single-storey bungalow, it requires elements such as:
- a suspended upper floor
- staircase
- additional structural reinforcement
- vertical plumbing and electrical distribution
- more complicated access during construction
Current benchmarks reflect that difference. Standard bungalow construction is priced below middle-class maisonette construction on a per-square-metre basis.
That does not mean a maisonette is always the wrong financial choice.
On smaller plots, building vertically can make much better use of the available land.
You can compare the two approaches in our guide to the cost of building a bungalow in Kenya.
What makes a 4-bedroom maisonette expensive?
1. Floor area
This is one of the biggest cost drivers.
Reducing a proposed house from 220 m² to 190 m² removes 30 m².
At approximately KSh 60,000 per m², that represents roughly:
KSh 1.8 million
A more efficient design can therefore make a substantial difference.
2. Bathrooms
Four-bedroom maisonettes often contain several bathrooms.
Making every bedroom ensuite increases plumbing, sanitaryware, tiling and waterproofing costs.
See our guide to plumbing costs in Kenya for more detail.
3. Roof design
A simple roof is generally more economical than a highly articulated roof with numerous valleys, ridges and intersections.
4. Finishes
Floor tiles, sanitaryware, cabinetry, countertops, lighting, doors and other finishes can move a project from relatively standard to very expensive.
See our guide to house finishing costs in Kenya.
5. Site conditions
A sloping plot or difficult soil may require additional excavation, retaining walls or foundation work.
Our guide to foundation costs in Kenya explains this stage in more detail.
6. Location
Building costs vary across Kenya because labour, transport and material availability differ by region.
If you already know where you intend to build, see:
- Cost of Building a House in Nairobi
- Cost of Building a House in Kiambu
- Cost of Building a House in Kisumu
- Cost of Building a House in Mombasa
What costs might not be included?
A headline construction estimate does not necessarily include every expense required to complete your project.
Depending on the estimate, you may also need to allow for:
- architectural services
- structural engineering
- quantity surveying
- approvals and statutory fees
- soil investigations
- boundary walls
- gate and driveway
- landscaping
- utility connections
- water storage
- external drainage
- contingency
- furniture and appliances
Always ask exactly what a contractor quotation includes.
Once your design is sufficiently developed, a Bill of Quantities can provide a much clearer picture of the project’s expected costs.
How should you compare contractor quotations?
Suppose three contractors quote:
- KSh 11.8M
- KSh 12.6M
- KSh 14.1M
The lowest quotation is not automatically the best.
Check:
- materials and specifications
- exclusions
- payment terms
- construction period
- warranties
- provisional sums
- whether all work has been included
Our guide to comparing construction quotes in Kenya explains what to look for.
You can also read what should be included in a building contractor quote.
Estimate your own 4-bedroom maisonette
Generic averages are useful for early research.
But the better question is:
How much might the maisonette I actually want to build cost?
MyJenga lets you enter details such as:
- location
- approximate floor area
- house type
- number of storeys
- finish level
and receive an indicative construction-cost range.
Frequently asked questions
How much does a 4-bedroom maisonette cost to build in Kenya?
A reasonable preliminary range for a middle-class four-bedroom maisonette is approximately KSh 10M–14M, depending heavily on size and specification.
Larger or premium maisonettes can exceed KSh 20 million.
Can KSh 10 million build a 4-bedroom maisonette?
Potentially.
At approximately KSh 59,868 per m², KSh 10 million equates to roughly 167 m² of construction.
The actual project must still account for design, location, site conditions, finishes and the precise scope of the estimate.
Is a maisonette more expensive than a bungalow?
On a per-square-metre basis, current published benchmarks place middle-class maisonettes above standard bungalows.
However, maisonettes can use smaller plots more efficiently because the house is distributed over multiple floors.
Does this estimate include the cost of land?
No.
The figures discussed here refer to construction. Land acquisition should be budgeted separately.
Final takeaway
For early planning, a four-bedroom maisonette in Kenya may require roughly KSh 10 million to KSh 14 million for a relatively standard or middle-class build.
But size matters enormously.
A 160 m² maisonette and a 220 m² maisonette are very different projects even if both have four bedrooms.
Start with a realistic construction cost per square metre, design around your actual budget, and then replace broad estimates with detailed costing and contractor quotations as your project develops.
