Nchenje Homestead, a sustainable house built in Maun, was designed to employ passive energy systems. The house was orientated to take a view up the Boro River, and so the orientation was challenging with a north-west aspect in an extremely hot climate. A large verandah to the north and openness to the nast to capture cooling breezes combined with the thermal mass of rammed earth create a comfortable living environment.
The house has a clip lock zinc aluminium-coated roof at a very flat slope so that the building sits as low as possible in the landscape and views over it are possible. On a gently sloping site, the house was raised on an earth platform over the floodplain enhancing the view while securing it from large floods of the Okavango Delta.
