The theme of this master thesis is the fictitious expansion of Tanaf, a nearly 3000 inhabited village in Casamance, Senegal. The basic idea is the further development of the village under the influence of the Baobab principle / water reservoir, with the objective of creating a new center at the extended backbone of the village. In doing so, attention is paid to preserving the trees, creating a new training center, an event area, an orphanage with an integrated emergency shelter for children from surrounding villages and a new market. The center of the site marks the new meeting point with integrated water storage. At the end of the main axis is a resting place on the secluded river. The basis of the structure is based on idealized cell forms of the Baobab, which are scaled to existing building sizes in order to carry on the graininess of the village.
