About this calculator
A standard machine-cut stone wall around a 50 by 100 plot near Nairobi costs roughly KES 480,000 to 560,000; a plainer upcountry wall, about KES 180,000 to 230,000.
What the calculator includes
- Foundation: trench, concrete footing and the stones below ground.
- Walling: machine-cut stones, mortar and, for the standard wall, reinforced concrete columns.
- Top finish: a concrete coping for the standard wall.
- Labour: fundis and casual workers for the days the job takes.
- Delivery and sundries: stone delivery, water, formwork timber and tools.
It doesn't include the gate, razor or electric wire on top, plastering or painting. Our perimeter wall cost guide prices those separately and explains every line.
How to use the result with a fundi
- Compare quantities, not just the total. Ask the fundi how many stones, bags of cement and lorries of sand and ballast they've priced. Big gaps usually mean a different wall.
- Check the specification. Columns every three metres, a proper footing and a coping cost more but last. A cheaper quote often leaves one of them out.
- Agree how labour is paid. Daily rates, per-metre rates and a fixed price for the job each shift risk differently.
- Buy materials yourself if you can. It keeps the quantities honest and you can check delivery.
Before you build
- Confirm your beacons. Have a surveyor point out the boundary beacons so the wall goes on your land, not your neighbour's.
- Check county rules. Some counties need approval for boundary walls and set height limits; the guide covers this.
- Plan drainage. Leave weep holes or gaps so rainwater doesn't build up behind the wall.
Frequently asked questions
How much does a perimeter wall cost per metre in Kenya?
About KES 5,400 to 6,600 per metre for a standard machine-cut stone wall near Nairobi, and about KES 2,100 to 2,600 per metre for a plainer upcountry wall, as of September 2026.
Why do fundis' quotes differ so much?
They're usually pricing different walls: with or without columns, steel, a proper footing or a coping. Compare the quantities in each quote against this calculator's bill of quantities.
Does the price include the gate?
No. The gate, wire or electric fencing on top, plaster and paint are extra. The perimeter wall guide lists typical prices for each.
Building the house too?
Our house construction cost calculator does for a whole bungalow what this calculator does for a wall: it measures the foundation, walls and roof from your plan (or a photo of it) and prices every phase, from the trenches to the paint.
