This free construction cost calculator helps you estimate the cost of building a house in Kenya before you speak to a contractor. It is built by Jowach Construction, a general construction company serving clients across Kenya, and it uses current planning rates for materials, transport and statutory fees.
These are the planning rates behind the calculator, as at 2 November 2026. They include materials at Nairobi depot prices, labour, finishes and fittings. They do not include transport, ground conditions, statutory fees or VAT.
| Finish level | Typical use | Planning rate per SQM |
|---|---|---|
| Economy | Standard rental units | KES 26,000 |
| Enhanced | Suburban maisonette | KES 38,000 |
| Premium | Luxury villa | KES 52,000 |
The calculator lets you choose the cement you plan to use, because a 50 kg bag can cost much more for structural grades than for general masonry cement.

|---|---|---|
| Rhino | General masonry and plastering | KES 705 |
| Simba | General construction | KES 730 |
| Mombasa / Nyumba | Structural and general use | KES 740 |

| Bamburi Duracem | Specialty, 42.5 grade | KES 1,130 |
| Bamburi Powerplus | Heavy structural, 42.5 grade | KES 1,290 |
The calculator covers all 47 counties. Each county belongs to a pricing zone with a material price index and an average cost per truck trip. Transport costs vary with distance, road condition, season and truck availability, so these figures are averages and you can enter your own supplier quote.

Using Jowach Construction planning rates as at 2 November 2026, building a house costs about KES 26,000 per square metre for an economy finish, about KES 38,000 for an enhanced suburban maisonette finish and about KES 52,000 for a premium luxury villa finish. These rates exclude transport, ground conditions, statutory fees and VAT, so your total will be higher. Use the construction cost calculator above for a full estimate.
You enter your room schedule or gross plinth area and choose a finish level, cement grade, region and ground conditions. The calculator multiplies the area by planning quantities for cement, sand, ballast, stones and steel, prices them for your region, then adds transport trips, labour and finishes, allowances for black cotton soil and water, statutory fees and VAT. The total is split into four construction stages.
It gives a planning estimate only, not a quotation. Real costs depend on your drawings, specifications, site and the market prices on the day you buy. For an accurate quotation, contact Jowach Construction on +254 704 264 302 or by WhatsApp.
In the calculator price list as at 2 November 2026, a 50 kg bag costs from about KES 705 (Rhino) to about KES 1,290 (Bamburi Powerplus), depending on brand and grade. Prices also vary by location and by how much you buy.
The headline figure is before VAT. VAT at 16% is shown separately and applied to materials, transport, labour and site services, but not to statutory fees or levies.
The calculator allows KES 45,000 plus KES 250 per square metre of gross plinth area as a planning figure for National Construction Authority project registration and county construction permits. Actual fees are set by NCA and the county government, so confirm them before you budget.
Black cotton soil is expansive clay that needs a stronger, deeper foundation. The calculator adds 25% more cement, 20% more sand and 30% more stone and ballast, plus KES 6,500 per square metre for foundation excavation.
The calculator converts quantities into weight and assumes a 10 tonne tipper truck. A 9 x 9 x 18 inch machine-cut stone is taken as 30 kg. It rounds up to whole trips and prices each trip by region.
Yes. Choose your county and the calculator applies the material price index and the average transport cost for its pricing zone. Zones far from Nairobi use provisional planning figures, so always confirm prices with local suppliers.
Transport cost depends on the distance from the supplier or quarry, road condition, the season, truck size and availability, and site access. The calculator uses an average cost per truck trip for each pricing zone and lets you enter your own supplier quote.
