Cost guide
What it costs to build a house in Kenya
The question everyone asks first. Here are honest market ranges, what moves them, and where people most often lose money, written by a contractor rather than by someone selling you a plan.
Would you rather just put your own numbers in?
The calculator does everything on this page for your specific size, finish and county, and adds the water, waste, approvals and boundary wall that guides like this one usually leave out.
Cost per square metre
Construction cost per m² in Kenya
The standard way contractors and quantity surveyors talk about price. Multiply by your floor area for a rough shell to finish figure.
Basic finish
KES 33,000 to 48,000 / m²
A sound, simple house. Everything works, nothing is decorative. Machine cut stone walls, plastered and painted. Box profile mabati roof on cypress. Ceramic floor tiles in wet areas, screed elsewhere or basic tiles throughout.
Standard finish
KES 48,000 to 78,000 / m²
What most family homes around Nanyuki are actually built to. Stone walls with a better external finish. Tile profile mabati or stone coated tiles. Porcelain floor tiles, timber ceilings with lighting detail.
High end finish
KES 78,000 to 140,000 / m²
Where the house itself is the point, and the budget reflects that. Feature stone or rendered elevations, larger spans and glazing. Timber or engineered floors, panelled and coffered ceilings. Bespoke joinery throughout, stone or quartz worktops.
A worked example. A 120 m² three bedroom bungalow at a standard finish of KES 62,000 per m² comes to roughly KES 7.4 million for construction. Professional fees, county approval, a soil test, a survey, water storage, a septic system and your contingency all sit on top of that, and together they commonly add another 20 to 35 percent.
Whole-house budgets
What a finished house costs
For people who think in bedrooms rather than square metres.
| House type | Typical size | Indicative total | Notes |
|---|---|---|---|
| 2 bedroom bungalow | about 80 to 100 m² | KES 3.5M to 7M | A first home, or a rental unit on a family plot. |
| 3 bedroom bungalow | about 110 to 140 m² | KES 5.5M to 10M | The most commonly built family house in Kenya. |
| 4 bedroom maisonette | about 180 to 250 m² | KES 9M to 18M | Two storeys, chosen where the plot is small or the view is upstairs. |
| 5 bedroom maisonette | about 250 to 350 m² | KES 14M to 30M and up | Usually a high end finish, often with a DSQ and landscaped grounds. |
| 1 bedroom cottage or Airbnb unit | about 50 to 70 m² | KES 3.5M to 6M | Furnished and ready to let. Common around Nanyuki and Timau. |
| Bedsitter block, per unit | about 18 to 25 m² | KES 550k to 900k | Cost per unit falls as you build more, because the roof and services are shared. |
Where you build
The same house costs different money in different counties
Materials cost what they cost standing on your plot, not in a Nairobi yard. Haulage is the main reason the same drawing is not the same price twice.
| Region | Against Laikipia | Why |
|---|---|---|
| Nanyuki and Laikipia | base | Our base. Stone comes from the Laikipia and Meru quarries, sand mostly from the Ewaso Ng'iro and Timau side. Cement and steel come up from Nairobi or Nakuru, which is the main reason materials here sit a little above Nairobi yard prices. |
| Nyeri and Mount Kenya west | -2% | Good quarry and hardware supply, short haulage. Steep sites and heavy rain are the usual cost drivers rather than materials. |
| Meru and Tharaka Nithi | -1% | Strong local stone supply. Access roads on shamba plots are often the deciding factor on the final price. |
| Isiolo and the northern corridor | +8% | Everything except sand and hardcore travels further. Water on site is often bought and carted, which is a real line item, not an afterthought. |
| Nyandarua and Nyahururu | +2% | Cold and wet for much of the year, which slows concrete and plaster work and lengthens programmes. |
| Samburu and Maralal | +15% | Long haulage on everything. Worth planning deliveries in full loads rather than trips. |
| Nairobi and Kiambu | base | The deepest supplier market in the country, so material prices are keenest here. Labour and land costs pull the finished figure back up. |
| Nakuru and Naivasha | -1% | Well supplied, with a strong second-hand and salvage market for timber and steel. |

What moves the number
What actually decides the price
Understand these and you can control your budget. Ignore them and your budget controls you.
Your soil, before anything else
Black cotton soil swells when it is wet and shrinks when it dries, and it is common across parts of Laikipia as well as the better known areas around Athi River and Kitengela. Building on it needs a deeper or engineered foundation, which can add hundreds of thousands of shillings before a wall goes up. A soil test at the start costs a fraction of a cracked house later.
Finishes, not structure
The shell of a house is surprisingly consistent in price. What separates a 5 million shilling house from a 12 million one on the same footprint is almost entirely the finishes: floors, joinery, kitchen, sanitary ware, ceilings and windows.
Site access and distance
If a lorry cannot reach the plot, every bag of cement and every load of stone is handled twice. Remote or steep sites can add five to fifteen percent to material costs before anything else. Fixing the access road first is usually cheaper than paying for it delivery by delivery.
Water and power on the plot
In town you connect. Outside it you build. Roof harvesting, tanks, a septic system or biodigester, solar or a Kenya Power connection are a package that commonly adds one and a half to four million shillings, and it is the item most often left out of a budget entirely.
How long it takes
A build stretched over three years costs more than the same build in ten months. Materials inflate, supervision runs longer and half built structures deteriorate in the rain. Building in one continuous run is usually cheaper than building in stages, if you can fund it.
The professional fees people forget
Architectural and structural drawings, county approval, a soil test and a survey all come before construction. Together they are commonly eight to fifteen percent of the build cost. Budget for them rather than discovering them.
Contingency
Keep eight to ten percent aside and do not touch it. Something on every site is different from what anyone could see from the surface. A project with no contingency is a project that stops.
Avoid these
The most expensive mistakes we see
Every one of these is common, and every one costs far more than doing it properly would have.
Taking the lowest quote
The lowest bid usually means something was left out, or that the contractor intends to make it back through variations later. Compare quotes line by line for what is actually included before you compare the totals.
Building without approved plans
A stop order halts your site, and an unapproved building is difficult to sell, mortgage or insure. Approval costs a fraction of what ignoring it costs.
Buying all the materials early
Cement has a shelf life, steel rusts and a site full of unsecured materials invites theft. Buy to programme. The exception is steel when the price is clearly moving, and even then only the structural requirement.
Skipping the drying on timber
Undried doors, floors and wardrobes shrink and twist once they are inside a warm finished house. Replacing them costs several times what drying the timber would have.
Designing before testing the ground
A beautiful plan drawn before anyone knew what the soil was doing is a plan that gets redesigned. Test first, draw second.
Forgetting the boundary and the road
A finished house behind an unfenced boundary on an impassable track is not a finished project. Put both in the budget at the start rather than finding them at the end.
Want a figure for your actual plot?
Send us the location, the plot size and the kind of house you have in mind. We will give you an honest budget range for free, and tell you if what you want cannot be built for what you have, rather than finding out halfway up the walls.
We build in Laikipia, Nyeri, Meru, Isiolo, Nyandarua, Samburu, Embu, Kirinyaga.
Building is expensive. Building twice is worse.
Talk to us before you commit to drawings or a contractor. An hour now is cheaper than a variation later.
