If you are planning to build a house in Kenya, one of the first questions you are likely to ask is:
How much does it cost to build per square metre?
The short answer is that there is no single construction rate that applies to every house.
The cost depends on what you are building, where you are building it, the quality of finishes you choose, the characteristics of your site and many other factors.
However, cost per square metre is still a useful starting point for estimating whether a project is within your budget.
According to the latest published industry benchmarks, residential construction costs in Kenya can range from approximately KSh 54,730 per square metre for a standard bungalow to around KSh 97,730 per square metre for a luxury maisonette.
The Architectural Association of Kenya‘s Status of the Built Environment Report 2025 reported the following residential construction benchmarks:
| Type of building | Approximate construction cost per m² |
|---|---|
| Standard bungalow | KSh 54,730 |
| Middle-class maisonette | KSh 59,868 |
| Standard low-rise apartments | KSh 68,837 |
| Luxury apartment block | KSh 90,013 |
| Luxury maisonette | KSh 97,730 |
These figures are useful benchmarks rather than quotations for an individual project.
So how much should you budget per square metre?
For someone doing preliminary planning, the figures above suggest a broad residential construction range of roughly:
KSh 55,000–100,000+ per square metre
But treating that as a universal building rate would be misleading.
A simple bungalow with modest finishes may sit near the lower end of the range, while a large maisonette with imported finishes, complicated structural work, extensive glazing and high-end kitchens and bathrooms can cost substantially more.
Your cost per square metre should therefore be treated as a planning estimate, not a contractor quotation.
Example
Suppose you want to build a 150 m² house.
At KSh 55,000 per square metre:
150 × KSh 55,000 = KSh 8.25 million
At KSh 70,000 per square metre:
150 × KSh 70,000 = KSh 10.5 million
At KSh 90,000 per square metre:
150 × KSh 90,000 = KSh 13.5 million
The same 150 m² house could therefore have a very different construction budget depending on its design, specification and location.
That is why estimating a building purely from the number of bedrooms can also be deceptive. Two four-bedroom houses might have dramatically different floor areas and finishes.
Current construction costs in Kenya
Construction costs have risen considerably over the past several years.
AAK reported that the benchmark cost of constructing a standard bungalow increased from KSh 48,750 per m² in 2024 to KSh 54,730 per m² in 2025, an increase of 12.27%.
Middle-class maisonettes rose from KSh 53,800 to KSh 59,868 per square metre over the same period.
Luxury maisonettes experienced an even larger increase, rising from KSh 84,000 to KSh 97,730 per square metre.
Material prices are one reason construction budgets can change so quickly. AAK reported, for example, that the average price of a bag of cement increased from approximately KSh 550 in 2021 to KSh 850 in 2025.
For anyone planning a project several months or years in advance, this means it is prudent to leave room for cost escalation rather than assuming today’s estimate will remain unchanged.
Construction cost by house type
Standard bungalow
The latest AAK benchmark puts a standard bungalow at approximately:
KSh 54,730 per m²
That would translate approximately to:
| Floor area | Indicative cost |
|---|---|
| 80 m² | KSh 4.38M |
| 100 m² | KSh 5.47M |
| 120 m² | KSh 6.57M |
| 150 m² | KSh 8.21M |
| 200 m² | KSh 10.95M |
These are simple mathematical estimates based on the industry benchmark, not project quotations.
A compact design, simple roof, locally available materials and restrained finishes can help control costs. Conversely, complicated roofs, large windows, extensive external works and premium finishes can push costs higher.
Middle-class maisonette
AAK’s latest published benchmark for a middle-class maisonette is approximately:
KSh 59,868 per m².
Using that rate:
| Floor area | Indicative cost |
|---|---|
| 150 m² | KSh 8.98M |
| 180 m² | KSh 10.78M |
| 200 m² | KSh 11.97M |
| 250 m² | KSh 14.97M |
| 300 m² | KSh 17.96M |
Again, these are preliminary estimates.
Two maisonettes of exactly 200 m² can still end up costing very different amounts.
Does location affect construction cost in Kenya?
Yes.
Labour rates, transport costs, availability of materials, local market conditions and the characteristics of the site can all vary by location.
Research published by Integrum for 2025, for example, showed noticeable differences between Nairobi/Central Kenya, Western/Nyanza and the Coast for several categories of residential development. Their published rates for standard bungalows were approximately KSh 54,730 per m² around Nairobi, KSh 57,080 in Western/Nyanza and KSh 58,590 at the Coast.
This may seem counter-intuitive if you expect Nairobi always to be the most expensive place to build.
But materials sometimes need to travel further to other regions, particular trades may be less readily available, and regional supply conditions can affect prices.
This is why a national average should never completely replace a location-specific estimate.
What affects construction cost per square metre?
Several factors can materially change the cost of your project.
1. Floor area
A larger house usually costs more overall, although the cost per square metre does not necessarily increase at exactly the same rate.
Some costs are relatively fixed, while others increase directly with the size of the building.
2. Quality of finishes
Finishes can have an enormous effect on your final budget.
Consider the difference between:
- locally sourced ceramic tiles and premium imported tiles
- standard aluminium windows and large bespoke glazing systems
- a simple locally fabricated kitchen and a premium fitted kitchen
- standard bathroom fittings and imported designer sanitaryware
The structural shell may be similar, while the finishing budget is radically different.
3. House design
Architectural complexity costs money.
A relatively simple rectangular bungalow is generally easier to construct than a house containing numerous corners, cantilevers, balconies, double-volume spaces and complicated roof geometry.
Good design does not have to mean expensive design.
In fact, designing with the budget in mind from the beginning can prevent expensive changes later.
4. Site conditions
The plot itself matters.
A steep site may require retaining walls and additional excavation.
Poor soil conditions may require a more substantial foundation.
A difficult-to-access property can increase transportation and logistics costs.
Consequently, two people building the same house design on different plots may not spend the same amount.
5. Location
Material delivery, labour availability and regional pricing influence the overall cost.
A site far from major suppliers can incur higher transport expenses, while specialist labour may need to travel to the project.
6. Roof design
Roofing can become a surprisingly large component of a building budget.
The type of roofing material matters, but so does the shape of the roof.
A straightforward roof structure will usually be less expensive than one with numerous valleys, ridges and complicated intersections.
7. Kitchens and bathrooms
These are among the most specification-sensitive parts of a house.
Cabinetry, countertops, sanitaryware, taps, shower fittings and appliances can move the budget considerably.
8. External works
A common budgeting mistake is concentrating only on the house itself.
You may also need to pay for items such as:
- boundary walls
- gates
- driveway and paving
- drainage
- landscaping
- water storage
- septic systems where necessary
- utility connections
- external lighting
These costs can be substantial.
Does the per-square-metre estimate include everything?
Not necessarily.
This is one of the most important questions to ask whenever somebody gives you a construction rate.
Different estimates may treat professional fees, statutory approvals, external works, contingencies, furniture, landscaping and other expenses differently.
Before comparing two numbers, make sure they are measuring the same thing.
A contractor saying, for example, “I can build for KSh 45,000 per square metre” may be quoting a different scope from another contractor quoting KSh 60,000.
The cheaper number is not automatically the cheaper project.
Ask exactly what is included and excluded.
For a serious project, a detailed estimate or Bill of Quantities prepared for your actual plans is considerably more informative than relying solely on a generic square-metre rate.
The Institute of Quantity Surveyors of Kenya describes its Building and Construction Costs Handbook as a pricing resource intended to help quantity surveyors and other construction professionals arrive at realistic project estimates.
Why contractor quotes can differ so much
Suppose three contractors quote for exactly the same project.
One quotes KSh 9.8 million.
Another quotes KSh 11.2 million.
The third quotes KSh 13 million.
That does not necessarily mean the KSh 9.8 million contractor is offering the best deal.
You need to understand:
- what each contractor has included
- the materials and specifications assumed
- provisional sums
- exclusions
- payment structure
- proposed construction period
- warranties
- whether key works have been omitted
Comparing only the headline price can create a false economy.
A structured comparison of quotations is much more useful.
How accurate is a cost-per-square-metre estimate?
It is useful for early-stage feasibility.
It can help answer questions such as:
- Can I realistically afford this project?
- Should I build 150 m² or 220 m²?
- Is my KSh 8 million budget remotely compatible with my proposed house?
- Should I simplify the design before paying for detailed plans?
But it becomes less useful as you move closer to construction.
A useful way to think about the process is:
Early idea → cost-per-m² estimate → architectural design → detailed cost estimate/BOQ → contractor quotations → construction
Each stage should give you greater cost certainty.
How can I estimate my own construction cost?
The simplest preliminary calculation is:
Estimated construction cost = floor area × estimated cost per square metre
For example:
You are considering a 180 m² maisonette.
Assume a preliminary rate of KSh 60,000 per m².
180 × 60,000 = KSh 10.8 million
You therefore have an initial construction estimate of roughly KSh 10.8 million.
You should then adjust your thinking based on:
- location
- finish level
- site conditions
- design complexity
- external works
- professional and statutory costs
- contingency
This is where a generic online calculation becomes more useful when it takes your actual project characteristics into account.
Calculate the estimated cost of your own project
Rather than applying one generic rate to every house in Kenya, MyJenga lets you estimate your project based on what you actually want to build.
Enter details such as:
- where you intend to build
- type of house
- approximate floor area
- number of storeys
- intended finish level
MyJenga can then give you an indicative construction-cost range for your project.

As your project becomes more concrete, you will also be able to use MyJenga to request and compare quotations from construction companies interested in building your project.
Frequently asked questions
How much does it cost to build one square metre in Kenya?
Current published residential benchmarks suggest roughly KSh 55,000 to KSh 100,000+ per square metre, depending on the building type and specification. AAK’s 2025 report puts a standard bungalow at about KSh 54,730 per m² and a luxury maisonette at about KSh 97,730 per m².
How much would a 100 m² house cost in Kenya?
At KSh 55,000 per square metre, a 100 m² house would have an indicative construction cost of approximately KSh 5.5 million.
At KSh 70,000 per square metre, it would be approximately KSh 7 million.
The actual cost depends on design, location, specification and site conditions.
How much would a 150 m² house cost?
Using a broad preliminary range of KSh 55,000–70,000 per m², a 150 m² house might have an initial construction estimate of approximately KSh 8.25 million–10.5 million.
Premium specifications can push the cost considerably higher.
Is KSh 50,000 per square metre enough to build in Kenya?
It may be possible for some projects, particularly where the design and finishes are carefully controlled. However, the latest AAK benchmark for a standard bungalow is already approximately KSh 54,730 per square metre, so KSh 50,000 should not automatically be assumed to be a safe national building rate.
Is cost per square metre the best way to budget for construction?
It is useful during early planning.
Once you have architectural drawings and clearer specifications, a project-specific cost estimate or BOQ will provide much greater precision.
Final takeaway
There is no single correct construction cost per square metre for every house in Kenya.
The latest published benchmarks indicate that residential construction can range from approximately KSh 55,000 per m² for standard housing to nearly KSh 100,000 per m² for luxury residential construction, before considering how the exact scope of a particular estimate is defined.
Use those figures to determine whether your idea is broadly financially feasible.
Then refine the estimate based on your actual house, location, floor area, finish level and site.
And when you are ready to move beyond estimates, compare quotations based on their complete scope — not simply the lowest headline number.
