How do you make buildings?

Thank you for your questions and I hope you've been patiently waiting for and answer. IO has been giving us a lot of questions and we are finally starting to catch up. For you answer we asked Pierre Kerr, ac210@freenet.carleton.ca to do some research.

Claude, there are many different kinds of buildings and each one is made in a different way. If you look at the tall buildings in downtown Ottawa, these are made from poured concrete. Concrete is a mixture of small stones, water and a mixture of chemicals called cement. This mixture is stirred in a large truck and poured into forms that are made of plywood. After a day or so, the concrete becomes as hard as rock.

Most houses are made by first building a frame out of wood and then covering it with a variety of materials such as brick or aluminum. This diagram is from Compton's encyclopedia and shows the parts that make up a typical house.
