The estimator uses per-square-metre rates from the IQSK Cost Handbook for Construction Works 2025/2026 — the most recent edition — and always shows a range (±12%) rather than a single figure because market rates genuinely vary. Treat the result as a realistic planning envelope, not a quotation — a registered quantity surveyor should price your actual drawings before you commit.
Building rates per square metre in Kenya (July 2026)
Quantity surveyors price construction in Kenya per square metre of floor area, with the rate depending on the building type, the finish level and the region. The table below shows the rates this estimator uses, in KES per m² and VAT-inclusive.

|---|---|---|---|---|
| Bungalow | Nairobi & Mt Kenya | 45,200 | 51,500 | 63,000 |
| Coast | 39,960 | 45,080 | 60,900 | |

Rates are sourced from the IQSK Cost Handbook for Construction Works 2025/2026 (Part C: Building Costs per Square Metre). Market rates vary — always get a quantity surveyor's estimate before you build.
How the estimate is calculated
Estimated cost = floor area (m²) × the regional rate per m² for your house type and finish level. Because real market rates vary by roughly 12% across published sources, the result is always shown as a low / likely / high range rather than a single figure. The likely figure then splits into the standard quantity-surveyor elemental proportions:
- Walling & structure — about 20% of the total
- Labour — about 23% of the total
- Professional fees & contingency — about 20% of the total
- Foundation — about 10% of the total
- Roofing — about 9% of the total
- Finishes (flooring, doors, painting) — about 7% of the total
- Plumbing — about 6% of the total
- Electrical — about 5% of the total
The estimate covers the construction cost only. It excludes the cost of land, boundary walls and gates, external works such as landscaping and boreholes, furniture and loose fittings, and finance costs. Nairobi and Mombasa fall in the highest regional bands; all 47 counties are mapped to three published regional rate bands to avoid false precision.
This is an indicative range, not a quotation — market rates vary with design, site conditions and material prices. Engage a registered quantity surveyor for a detailed estimate before you build.

Building costs in Kenya, explained
How much does it cost to build a 3-bedroom house in Kenya?
A standard 3-bedroom bungalow of about 110 m² costs roughly KES 5.0M – 6.3M to build in Nairobi in 2026, at around KES 51,500 per m²; a 3-bedroom maisonette typically runs KES 6.0M – 7.6M. A small economy build can come in from about KES 2.0M, while premium finishes push costs well above KES 6M. The final figure depends on size, finish level and county — use the estimator above to get a range for your exact combination.
What is the cost of building per square metre in Kenya?
In 2026, building costs in Kenya range from about KES 39,960 per m² for an economy bungalow to about KES 60,050 per m² for a premium maisonette, with standard-finish homes falling between KES 45,080 and 51,500 per m² depending on region. Apartment blocks run from about KES 37,940 per m² (low-rise, Coast) to KES 69,400 per m² (luxury). These figures are based on the IQSK Cost Handbook for Construction Works 2025/2026.
How much does it cost to build a 3-bedroom house in rural Kenya?
Building in rural Kenya is generally cheaper than in Nairobi or Mombasa because labour is less expensive, though transporting materials can offset part of the saving. An economy 3-bedroom bungalow of about 100 m² can cost roughly KES 3.7M – 4.7M in the Western & Nyanza region, and a compact, simply finished build can come in lower. Region matters less than finish level and size — an economy finish saves 10–15% off standard rates.
