How to treat the evolution of the house?

The earliest houses were stone houses or earth houses built by hand. The roof of this house is covered with grass and is conical.

Then there is a thatched cottage, a house made of grass.

Later, all kinds of bricks and tiles were widely used to build houses. So after careful carving, various forms of houses were scientifically spliced.

The development of modern science and technology has changed greatly in essence. A large number of artificial materials such as reinforced concrete are used, and more attention is paid to the decoration inside and outside the house. High-rise buildings followed.

With the development of science and technology and the demand of human beings, the fourth generation of houses will appear in the future.
