We are a Nairobi based bureau of architects and researchers charting explorations into architecture and urbanism within nature. Our work addresses the anthropological and geological context of the African city as a means to confront the complexities of our contemporary rural and urban lives. 

The bureau is driven to develop systems and structures that improve the human condition, without negatively impacting the natural environment and social fabric of our communities. We navigate a return to the limitless curiosity of our early ancestors, conducting playful and intensive research studies into caves within and around Nairobi. These studies form part of a broader decoding of pre and post colonial conditions of the city, explored through drawing, storytelling, construction, and the curation of performative events of resistance.

We also work to reconcile the often disjointed linkage between academia and practice by engaging multiple schools of architecture and studios around the world, where we lecture and review student work. Our evolving objective here being to better bridge the uneasy gap between these two standpoints, especially from our African position. 

Our ground-mending history

“The Fabian Colonial Bureau was founded in 1940, and was the first of such groups that provided the British Labour MPs with the research, networking, and publications necessary to influence the nature of British colonial rule throughout the empire. By the early 1950s though, there was a shift in British anticolonial organizations as the opposition began forming movements to more stridently challenge Churchill’s Conservative government. The African Bureau, established in 1952, represented significant departures from the original Fabian Colonial Bureau. It sought to influence the direction of colonial development policies, and to expose the injustices of colonialism and bring the anachronistic form of governance to an end. The Second World War brought vast changes to Kenya, changes that exposed the inequities of British colonial rule, galvanizing indigenous discontent and channeled it into a mass resistance movement that would be called Mau Mau”. [ Caroline Elkins, Britain’s Gulag ].

These movements of resistance not limited to Kenya were always orchestrated from the rural hinterlands of natural systems such as forests, caves, valleys, and mountains, constantly in tension with the disjointed colonial towns and cities. So by definition the post colonial African city cannot be fully understood without the past and present realities of the rural backdrop, a friction of what we call rural-urbanity.

At Cave_bureau we underscore and root this heritage without any political allegiances, and instead from a geological and indigenous alliance, confronting the neoliberalist permutations of colonialism and environmental degradation that persists today. We craft strategies across rural and urban lands, confronting these forces creatively with the communities that inhabit them. It is by design that this dark and yet rich history is not taught in schools, both by former colonised and colonising states, in any great depth or complexity. While within academia and architectural practice this past has only recently been given attention when speaking about the rich future of the African city or what extends beyond it. To this end or indeed beginning, we have embarked on an ongoing journey to investigate and integrate this history within architectural research, pedagogy and practice, to literally mend the ground as well as our imaginations when addressing the conjoined efforts to both decolonise and decarbonise Africa’s rural and urban territories.
