FIRST CONSTRUCTION MATERIALS

A very long time ago, people did not build homes. They slept in forests and caves, which were dark and did not have windows.

 People used wood and plants to make shelters - simple places to sleep in. They were at first very simple and perhaps lasted only a few days or months. People cut wood from trees to make the shape of the shelter. Then they used other plants to make the roof and the walls. The very simplest shelters leave no traces, that is why we can say little about very early construction.

 The first houses were made from dry plants like straw. These houses were not very strong.

The Ancient Egyptians built houses with bricks made of mud and straw. They put the mixture into moulds and left them in the sun to dry. Then they built walls with the bricks and put wet mud 0n top. There were holes in the walls for windows and doors. Egyptian houses had flat roofs. People often slept on the roof because N was cool. In the past other people in Asia, Africa, and South and North America built mud houses, too.

 Some people in the past built houses rom stone because it was strong. Poor people lived in small houses with only one room. Important rich people built stone castles to live in, which took many years to build.

The Ancient Greeks built houses with mud bricks n top of stone blocks. The roofs were usually made of tiles. The Incas lived in Peru. They built houses with stone blocks. Each block was carefully cut and polished so the houses looked great when they were finished.

 The Ancient Chinese people built wooden houses. They had long roofs made of bamboo Many Chinese houses were built on platforms to protect the wood from water.

The Ancient Romans built houses with wood, mud, and stone. They also used some materials that we use today, like concrete
