The Cape Town city grid is orientated at 45° off the north/south axis which complicates sun control in buildings. For the Breebloem tower, proposed for construction on a property neighbouring Gawie’s 18th century office building, his solution was to twist the building to the preferred axis to allow the four elevations to be sun screened effectively according to their aligned orientations.

The small site allows for a central structural services shaft from which the floor plates are cantilevered. The circular plan of the shaft aids the erection of the spiralling plates and also allows for a unique parking solution below ground with four levels of discs onto which cars are mechanically placed and which rotate to accept the next vehicle.
