Cave_bureau is a Nairobi-based bureau of architects and researchers charting explorations into architecture and urbanism within nature. Our work addresses and works to decode both anthropological and geological contexts of the postcolonial African city, explored through drawing, storytelling, construction, and the curation of performative events of resistance. The bureau is driven to develop systems and structures that improve the human condition, without negatively impacting the natural environment and social fabric of communities. By conducting playful and intensive research studies into caves within and around Nairobi, we aim to navigate a return to the limitless curiosity of our early ancestors while confronting the challenges of contemporary rural and urban living.
