A water collecting marketplace.
The Kariakoo market in Dar es Salaam, Tanzania, is such an example. Built in 1974 by the architect B.J. Amuli, the building offers three layers of market area and forms the centre of the Kariakoo market which is spread out in the neighborhood. The building is perfectly adapted to its function, but also to its environment. It provides for the necessary air circulation and the roof exists of a series of gigantic funnels to harvest the rain, to be stored in underground collection tanks.
