Cost to build a 200 sqm house in Mombasa in 2026

Updated 2026 · Kenya · Reference estimate

In short: for a 200 sqm house in Mombasa, expect roughly 7,840,000 KSh for an economy finish, up to 19,600,000 KSh for high-end. Plan for about 401 bags of cement, 3,198 blocks, 3,177 kg of steel and 39.7 m³ of concrete. These are the items a contractor can inflate, so these are the numbers to have proven.

For a two-storey house, the structure (concrete, steel, cement) roughly doubles, while the ground footprint is divided by the number of floors.

How to avoid an inflated quote in Mombasa

On a site managed from abroad, overcharging almost always hits three areas: structural materials (cement, steel), inflated quantities, and overbilled labour. Three simple reflexes:

Always compare the quote you receive to an independent reference estimate like the one above. A 10 to 15 percent gap is normal; beyond that, ask for explanations.
Pay by stages, never more than 20 to 25 percent upfront, and demand proof before each stage (a photo of the rebar before pouring, cement bags counted at delivery).
Where possible, buy the major materials yourself and have them delivered to site, rather than advancing cash to the contractor.

The figures above are orders of magnitude for Mombasa. For your exact project, describe your house on nokah or import an existing plan: you get the 3D plan, the detailed bill of quantities and a stage budget in Kenya's currency. You then face your builder with numbers they cannot argue with.
