*Based on a standard 3-bedroom bungalow (~100sqm) in Nairobi metro, 2026 prices. Costs vary by location and contractor.
What Affects the Cost of Building?
Before looking at specific numbers, understand the key factors that determine your total cost:
- Location: Building in Nairobi is more expensive than rural areas. Transport costs for materials vary by distance from suppliers.
- House design: A simple rectangular bungalow is cheaper than an L-shaped or multi-story design. Complex rooflines add cost.
- Finish level: The difference between basic and high-end finishes can double the total cost.
- Contractor: Rates vary significantly. Always get at least 3 quotes and check references.
- Soil conditions: Rocky or swampy ground requires more expensive foundation work.

Tips to Save Money Without Cutting Corners
- Buy materials in bulk: Cement, steel, and aggregates are cheaper when bought in larger quantities. Use JengaHub to compare cement suppliers and get the best prices.
- Get a proper BOQ: A Bill of Quantities from your architect prevents over-buying and helps you budget accurately.
- Build in phases: Many Kenyans build in stages as money becomes available. Start with foundation and walling, then roof, then finishing.
- Source locally: Buying aggregates (sand, ballast) from nearby quarries saves on transport costs.
- Don't skimp on the foundation: This is not where you save money. A weak foundation causes cracks and structural problems that are expensive to fix.
- Get multiple quotes: Compare contractors on JengaHub and always get at least 3 quotes before committing.
Cost Per Square Metre in Kenya (2026)
A common way to estimate costs is by price per square metre of floor area:
| Finish Level | Cost/sqm (KES) | 100sqm House |
|---|---|---|
| Simple (basic finishes) | 25,000 – 35,000 | 2.5M – 3.5M |
| Medium (good quality) | 35,000 – 55,000 | 3.5M – 5.5M |
| High-end (premium finishes) | 55,000 – 80,000+ | 5.5M – 8M+ |
Hidden Costs to Watch Out For
- County building permits: KES 20,000 – 50,000 depending on area
- NEMA environmental assessment: Required for some areas
- Water & electricity connection: KPLC and county water fees
- Fencing and gate: Often forgotten in the initial budget
- Transport of materials: Can add 5–15% depending on distance
- Price increases: Material prices fluctuate — buy cement and steel early when prices are good
