Building Construction
1. Building construction has its own history, which is marked by a number of trends. One of these trends is increasing durability of the materials. The first building materials were perishable such as leaves, branches and animal hides. Later people began to use more durable natural materials such as clay, stone, timber. Finally, synthetic materials such as bricks, concrete, metals, plastics were used in building.
2. Another trend is quest for buildings of greater height and span. It was possible by the development of stronger building materials and by knowledge of how materials behave and how to exploit them to greater advantage. The third trend involves the degree of control exercised over the interior environment of buildings: increasingly precise regulation of air temperature, light and sound levels, humidity, air speed.
