The walls and foundations of the buildings are made of large earth blocks similar to general local wall building practice. The roofs are domed or vaulted rather than flat and are built using small earth bricks rather than large timbers. No formwork is needed during construction. Hand-moulded, sun-dried earth bricks and mortars are used. No cement is added and very little special equipment is needed. The use of earth bricks suits the local climate, where it rains only infrequently but in short, intense showers. Smooth angled curves and large gutters help to ensure a good flow of water off the roof so that there is no water damage, even in periods of very heavy rainfall. The buildings are strong and have a predicted life of many years, providing that they are adequately maintained. http://www.bshf.org/en/about/whawards/projects.php?pID=00011
Explanation: Each of the Three Little Pigs built a house:
- one of straw,
- one of sticks, and
- one of stone.
Had it not been for the Big Bad Wolf, they might all be standing today. After all, thatched roofs and timber houses can be pretty permanent. But as the 3 Little Pigs found out, and as the pigs of Animal Farm might have told them, some permanent construction techniques are more permanent than others.
