Cost of building a house in Kenya (2026)
25 September 2026 · 6 min read
Kenyan builds are quoted in shillings per square metre, and those quotes vary more than they should: some include professional fees and county approvals, most don't. Here is what a family house costs to build in 2026 with a contractor, what the figure covers, and what to add on top of it.
A three-bedroom, two-bathroom house of about 125 m², standard finishes, built by a contractor in Nairobi with a boundary wall, costs about KSh 9.9 million all in — between KSh 8.5 million and KSh 11 million. Land is extra. The house alone is KSh 50,000–62,000 per m². Rates checked September 2026.
The price per square metre
The rate per square metre is for the house alone. A house built by a contractor, from foundations to finishes. It excludes land, professional fees, approvals and anything outside the walls. The totals here add what a real build also pays for — site preparation, drains and connections, a boundary wall and gate, plans and approvals, a 15% contingency and prices rising over a year-long build.
| Finishes | House, per m² | 3-bed, all in |
|---|---|---|
| Basicabout 85 m² | KSh 38,000–48,000 | KSh 5,420,000 |
| Standardabout 125 m² | KSh 50,000–62,000 | KSh 9,930,000 |
| High-endabout 175 m² | KSh 70,000–95,000 | KSh 19,900,000 |
A higher finish costs more per square metre and the rooms get bigger too, which is why the high-end house comes to more than twice the basic one.
By the size of the house
The same standard finishes, built by a contractor in Nairobi, for a smaller or a bigger house:
| House | Floor area | All in |
|---|---|---|
| 2-bedroom house | 100 m² | KSh 8,020,000 |
| 3-bedroom house | 125 m² | KSh 9,930,000 |
| 4-bedroom house | 145 m² | KSh 11,400,000 |
| 5-bedroom house | 170 m² | KSh 13,300,000 |
Where the money goes, phase by phase
The standard house above, split the way it is built. Each phase carries its share of the contingency and of prices rising while it waits its turn. The split follows Lesel Buildworks' stage percentages for Kenyan houses, July 2026.
| Phase | Likely | Share |
|---|---|---|
| Plans, approvals and fees | KSh 411,000 | 4% |
| Site preparation | KSh 229,000 | 2% |
| Foundation | KSh 1,210,000 | 12% |
| Walls up to the roof | KSh 1,910,000 | 19% |
| Roofing | KSh 1,240,000 | 12% |
| Windows and doors | KSh 796,000 | 8% |
| Electrical and plumbing | KSh 1,400,000 | 14% |
| Plastering and finishes | KSh 1,760,000 | 18% |
| Boundary wall, drains and paths | KSh 964,000 | 10% |
| Total | KSh 9,930,000 | 100% |
Budgeting by phase is what catches an overspend while there is still a choice to make: if the foundation has used its budget and the walls haven't started, you know now, not at the roof. More on that in construction costs by phase.
What moves the price
Where you build
Nairobi and surrounds sets the price. Against it:
- Mombasa and the coast: about 7% more
- Kisumu and the west: about 4% more
- Another town: about 5% less
- Rural home: about 12% less
The coast and the west are Integrum's figures for a standard bungalow; other towns and rural homes are allowances.
Who builds it
Hiring your own builders and buying the materials yourself comes to about 11% less than a contractor. The contractor's margin goes, but more is lost to waste, theft and delays, and someone has to supervise every day — so it only saves money when someone you trust is on site.
The ground
- Clay or black cotton soil, dug out to firm ground and backfilled: about 4% more overall.
- Rock near the surface, broken out for the foundations: about 3% more.
- A sloping site, with stepped foundations and some retaining: about 4% more.
- Wet ground or near a wetland, usually a raft foundation, drains and a raised floor: about 16% more. It also needs approval from NEMA, which licenses building near wetlands and riparian land before work starts, and some wetlands can't be built on at all.
Going up instead of out
The same 125 m² over two storeys comes to about 5% more. The footprint halves, so there is less foundation and roof, but the upper floor needs a concrete slab, a stair and a heavier frame.
Prices rising while you build
Materials in Kenya are rising about 6% a year, so work done late in a build costs more than the same work done at the start. The totals here allow for a 12-month build starting now.
Extras most houses here need
| Item | Typical cost |
|---|---|
| Boundary wall, per metre | KSh 3,000–6,000 |
| Gate (allowance) | KSh 40,000–120,000 |
| Borehole, installed | KSh 600,000–1,500,000 |
| Septic tank | KSh 120,000–300,000 |
| Solar power for a family house | KSh 250,000–600,000 |
Worth knowing about building in Kenya
- Black cotton soil, common around Nairobi and Kitengela, has to be dug out deeper and built on a stronger foundation. The foundation is where it shows.
- Building near a wetland or on riparian land needs a licence from NEMA.
- A borehole is a big-ticket item: drilling alone averages KSh 250,000 to 1.2 million, and a pump, tank and pipework add KSh 100,000–300,000.
- Architects' and quantity surveyors' fees, and county approvals, sit on top of the rate per square metre.
Where these figures come from
Every rate is quoted from a named, dated source, checked in September 2026. Where nothing published could be found, the figure is a quantity surveyor's allowance and marked as one.

An estimate from published rates is for budgeting, not a quote. Before you sign with a builder, get a bill of quantities priced for your plans and your plot.
Price your own house
The building cost calculator for Kenya works from these same rates. Tell it the bedrooms, bathrooms, floors, ground and finish, and it prices your house phase by phase. In Trace My Build, one tap turns the estimate into phase budgets, and every payment after that is tracked against them.
Building somewhere else? Zimbabwe, Nigeria, South Africa or Ghana.
