From the History of Building
Man has always been a builder. The first houses in different countries of the
world were made of wood. In other regions the most convenient building material
was stone.
The ancient Egyptians erected temples, palaces. Having dried the bricks in the
sun, they put up four walls, and above these they placed a flat roof. The roof was
flat because there was very little rain in Egypt. Egyptian builders gave the world
the column which has played an important part in the history of building. Most of
the buildings of old times were based upon the column and beam method of
construction.
The Greeks built a slanting roof because there was much rain in their country.
The Romans added the arch, thus increasing strength and beauty to their buildings.
Since the middle Ages, brickwork has been in constant use everywhere.
In our country architecture flourished for the first time in Kiev Russ. The
churches of the time were strong buildings with thick walls and small windows.
During the last hundred years many new methods of building have been
discovered. The use of precast concrete is a very advanced construction technique.
Nowadays houses are often built of complete concrete structural units which are
factory-made and assembled on the spot.
