O/S Architecture is a Nairobi-based architecture practice. We design and deliver thoughtful and considered buildings, interiors and public spaces.
We approach each project with a sense of curiosity, rigour, and enthusiasm.

We are committed to contemporary design and innovation, and believe architecture has the potential to make a significant contribution to culture and the built environment.

We are sensitive to the ambitions of our clients and work collaboratively to develop creative responses that exceed expectations.

We work across a range of scales, budgets, and typologies, carefully balancing pragmatism with potentiality.

We understand buildings as contributions to the environment, informing a complex and discursive design process that negotiates the relationship between buildings (objects) and their contexts (subjects).
