Top Foundation Designs for Homes in Kenya
1. Strip Foundations
Strip foundations are common in Kenya due to their affordability and suitability for various soil types.

- Cost: Ksh 2,000–4,000 per square meter.

2. Raft Foundations
Raft foundations, also known as mat foundations, distribute the building’s weight over a large area, making them ideal for weak soils.
