Additions and Alterations
The Social Security Commission had purchased an existing three-storey office block on a prominent corner in the CBD of Keetmanshoop and requested assistance with the upgrading of the building. The original building had been constructed in the mid 1960’s and very little has been done to it since. It is an old modernist building forming a self-contained island with no relation to exterior landscaping or street space, and thermally extremely inefficient. The new design proposes the demolition of a derelict ground floor portion and addition of a double story rentable office space that encloses a new courtyard space with planting and relaxation space for shelter from the harsh desert sun. The existing offices are re-designed to maximise interrelationships with the new courtyard and views to the park across the road. Extensive sunscreens provide privacy, reduce solar heat gain and glare inside the offices, and allow for the installation of large windows behind that maximise the ingress of natural light. Heat reflective roofs with clerestory lighting into the central spaces, with the installation of photo-voltaic panels over a large portion of the roofing, will ensure a significant reduction in electricity consumption. Air-conditioning, lighting and other services will be designed to be energy efficient. Indigenous planting and benches on the street enhances the interaction of the building with pedestrians.
