Maisonette Construction in Kenya: When Two Storeys Are Worth It
from KES 60,000 / m²
The maisonette premium is real, and sometimes worth paying
A maisonette costs KES 60,000 – 120,000 per square metre against a bungalow’s 45,000 – 90,000. Per square metre of finished accommodation you are paying meaningfully more, and it is worth being clear about why before deciding.
The extra cost is structural: a suspended slab between floors, heavier foundations carrying two storeys, a staircase consuming floor area on both levels, and taller scaffolding and services runs.
When it is the right answer
A small or expensive plot. In Kilimani, Kileleshwa or Parklands, where the plot is the dominant cost, going up is far cheaper than buying more ground.
A plot you want to keep open. A maisonette leaves more garden, more parking and more room for a future extension on the same land.
Separation. Bedrooms upstairs and living below is a genuine lifestyle difference that a lot of families want and that a bungalow cannot easily replicate.
What a 4-bedroom maisonette costs
KES 8M to 16M and up, depending overwhelmingly on finish level rather than on size. The spread in that range is finishes, joinery and fittings, not the structure.
The mistakes we are called in to fix
A staircase designed last. It is the hardest element to move once the slab is cast, and a poorly placed one wastes floor area on both levels permanently.
Foundations sized for one storey. On black cotton soil, common across the James Gichuru corridor and much of Lavington, a maisonette needs meaningfully deeper foundations than the same footprint as a bungalow, and that has to be in the design and the BQ from the start rather than discovered at excavation.
A water tank at the wrong height. Two storeys change the gravity feed arithmetic completely. It is a small detail that becomes an expensive retrofit.
