The amaNgwane people, who live in the foothills of the Drakensberg Mountains, designed and built a very successful, but simple dwelling. This was in response to the need to build housing, using local materials. Flexible poles were set in a circle and then bent over and fastened towards the center. These formed the upright framework. Other thin poles were woven in-between to complete and strengthen the frame. This was an ideal shape, as a domed shape is very strong with the compressive forces being distributed over the whole frame. In this way they could withstand the strong winds that blow in this area. By using natural materials they were very environmentally friendly. The frame was then covered with bundles of grass. This provided a good insulating layer so the dwellings were warm in winter and cool in summer. 2.2.1 What type of structure is described? (1) 2.2.2 Give ONE natural material that was used by the amaNgwane people for building these dwellings. (1) 2.2.3 What was the ADVANTAGE of using natural materials? (1) 2.2.4 How was the structure strengthened against the forces that could act upon it? (2) 2.2.5 Give the MAIN purpose of using grass to cover the framework.
