Like a jig-saw puzzle the square or rectangular pieces can be arranged in a U-shaped pattern with equidistant projections or an L-shaped plan with the outer arm or extension generally housing the kitchen, downwind from the living areas to ensure clean fresh air, with the south west air currents carrying the smoke away. Kitchens and toilets were seldom within the main structure, but situated separately. The verandas and corridors around the house and those running the length and breadth of the house prevented direct sunlight from falling on the main walls. This aspect of the design along with ventilators on the triangulation of the roof ensured cool air inside the rooms, at a time before electricity became widely available.
