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.
Kiambu is one of Kenya’s most active residential construction markets.
Areas such as Ruiru, Juja, Kiambu Town, Kikuyu, Limuru and Thika continue to attract homeowners building family homes, maisonettes and rental properties.
But how much does it cost to build a house in Kiambu?
For preliminary planning, a standard residential house in Kiambu may cost roughly:
KSh 55,000–65,000 per square metre
The final cost depends on your house type, floor area, finishes, location within the county, site conditions and contractor pricing.
For the wider national picture, see our guide to construction cost per square metre in Kenya.
Current construction cost per square metre in Kiambu
Published 2025 construction rates for the Nairobi and Mt. Kenya region provide a useful benchmark for Kiambu:
| Building type | Approximate cost per m² |
|---|---|
| Standard bungalow | KSh 54,730 |
| Middle-class maisonette | KSh 61,070 |
| Luxury bungalow | KSh 71,700 |
| Luxury maisonette | KSh 94,270 |
These figures should be treated as planning benchmarks rather than fixed contractor prices.
AAK’s national benchmark similarly placed standard bungalow construction at KSh 54,730/m² and middle-class maisonettes at KSh 59,868/m² in 2025.
How much would a house in Kiambu cost?
Using KSh 55,000–65,000 per m² as a preliminary range:
| House size | Estimated construction cost |
|---|---|
| 90 m² | KSh 4.95M–5.85M |
| 100 m² | KSh 5.5M–6.5M |
| 120 m² | KSh 6.6M–7.8M |
| 150 m² | KSh 8.25M–9.75M |
| 200 m² | KSh 11M–13M |
| 220 m² | KSh 12.1M–14.3M |
A 200 m² house, for example, could therefore require a preliminary construction budget of approximately KSh 11M–13M.
Premium specifications can push the cost significantly higher.
How much does a 3-bedroom house cost in Kiambu?
A compact three-bedroom bungalow might be around 90–120 m².
Using current benchmark rates, that suggests approximately:
KSh 5M–7.8M
depending on size and specification.
For a fuller breakdown, see Cost of Building a 3-Bedroom House in Kenya.
How much does a 4-bedroom maisonette cost in Kiambu?
A four-bedroom maisonette may fall around 160–220 m².
Using approximately KSh 61,000 per m²:
- 160 m²: about KSh 9.8M
- 180 m²: about KSh 11M
- 200 m²: about KSh 12.2M
- 220 m²: about KSh 13.4M
That makes a typical middle-class four-bedroom maisonette in Kiambu roughly a KSh 10M–14M project before major premium upgrades or unusual site costs.
See our detailed guide to the cost of building a 4-bedroom maisonette in Kenya.
Does the area within Kiambu affect the cost?
Yes.
Kiambu County covers a large and varied area.
Building in Ruiru or Juja may involve different conditions from building in Limuru, Kikuyu or a more rural part of the county.
Factors that can affect your cost include:
- distance from major material suppliers
- road access
- slope
- soil conditions
- availability of labour
- security and site logistics
- water and electricity availability
The construction rate for the house itself is therefore only part of the picture.
Why site conditions matter in Kiambu
Some plots require substantially more groundwork than others.
A flat site with good soil and convenient access may be relatively straightforward.
A sloping site may require:
- excavation
- retaining walls
- additional drainage
- more substantial foundation work
These costs can quickly alter the economics of the project.
See our guide to foundation costs in Kenya for more detail.
Bungalow or maisonette?
A bungalow may be attractive if you have sufficient land and want a relatively simple single-storey home.
The current regional benchmark for a standard bungalow is about KSh 54,730 per m².
A maisonette costs more per square metre but uses land more efficiently because part of the floor area is stacked vertically.
If your plot is relatively small, that can be valuable.
Compare:
Can KSh 10 million build a house in Kiambu?
Yes, depending on the design.
At KSh 55,000 per m²:
KSh 10M ÷ KSh 55,000 ≈ 182 m²
At KSh 61,000 per m²:
KSh 10M ÷ KSh 61,000 ≈ 164 m²
That means a KSh 10 million budget could potentially support a reasonably substantial standard home if the design and finishes are controlled carefully.

Don’t forget other project costs
The main house is not necessarily your entire project budget.
You may also need to pay for:
- architectural and engineering services
- quantity surveying
- approvals
- boundary walls
- gate
- driveway
- drainage
- water storage
- septic system where required
- landscaping
- utility connections
- contingency
These costs can be especially important on undeveloped plots.
Once you have detailed drawings, a Bill of Quantities can help you understand the full project more clearly.
How to get a more accurate estimate
Start with:
- exact town or area
- house type
- floor area
- number of storeys
- finish level
- site conditions
Then move from broad benchmark rates toward detailed drawings, costing and actual contractor quotations.
When you begin requesting bids, make sure you understand how to compare construction quotes in Kenya rather than choosing solely on the lowest price.

Frequently asked questions
How much does it cost to build per square metre in Kiambu?
For preliminary planning, roughly KSh 55,000–65,000 per m² is a useful range for standard residential construction, depending on the house type and specification.
How much does a 100 m² house cost in Kiambu?
At KSh 55,000–65,000 per m², approximately KSh 5.5M–6.5M.
How much does a 200 m² house cost?
A preliminary estimate would be approximately KSh 11M–13M for standard construction.
Does the cost include land?
No.
These figures refer to construction costs. The cost of acquiring the plot should be budgeted separately.
Final takeaway
For early planning, residential construction in Kiambu can reasonably be estimated at around KSh 55,000–65,000 per square metre for standard homes.
A compact 100 m² house might therefore cost roughly KSh 5.5M–6.5M, while a 200 m² project might fall around KSh 11M–13M before site-specific and external costs.
Use those figures as an affordability check rather than a quotation.
Then refine the estimate around your exact location, house size, specification and site.
