On Building in Kigali

Kigali is a city that rewards close reading. Its hills, wetlands, and rapid growth create a design brief that is unlike anywhere else in the region. To build well here, you first have to understand what is already there.

The city's topography is its most distinctive feature. Building on a slope means thinking about orientation, drainage, and access in ways that flat-city planning simply does not require. Roads that fight the terrain cost more to build and more to maintain. Buildings that ignore their orientation are uncomfortable to occupy. These are not aesthetic problems; they are technical ones with aesthetic consequences.

The wetlands are a second layer of complexity. Kigali's valleys hold water in ways that the surrounding hills do not. For decades, these areas were treated as voids to be filled or barriers to be crossed. We think that is wrong. Wetlands regulate temperature, absorb flood water, support biodiversity, and provide some of the most interesting public spaces in the city.

The third factor is speed. Kigali is growing fast. The gap between the housing that exists and the housing that is needed is widening. That gap cannot be closed by building slowly, carefully, and expensively. It requires systems: modular approaches, typologies that can be repeated with variation, construction methods that local contractors can build without specialist equipment.

These three conditions: topography, ecology, and scale of need. They shape every project we take on in Kigali. They are constraints, but they are also the brief.
