Affordable Incremental Housing

Kimihurura – Kigali, Rwanda

Affordable housing rarely arrives all at once. In Rwanda, families often build as resources become available, adding rooms over time rather than completing a fixed house in a single phase.

Affordable housing rarely arrives all at once. In Rwanda, families often build as resources become available, adding rooms over time rather than completing a fixed house in a single phase. This research project turns that reality into the organizing idea. The proposal begins with a compact, functional core and establishes a clear sequence for expansion toward a home of up to roughly 100 square meters and four bedrooms.

Wet areas, circulation, structure, and future room locations are planned from the beginning, so each phase can work on its own without making the next phase more expensive or wasteful. The result is not one universal house but a disciplined framework that can respond to changing household size and income. Journeyman International used the study to connect affordability with long-term dignity: families can invest gradually while retaining light, ventilation, privacy, and a coherent plan. It remains a prototype, intended to support further local testing and adaptation rather than prescribe a single way of living.
