What is the biggest feature of Jiangnan folk houses?

1. The overall layout of the houses in the south of the Yangtze River is roughly the same as that of the quadrangles in the north, but the layout is generally compact, and the courtyard occupies a small area to adapt to the characteristics of high local population density and less cultivated land.

2. Houses in the south of the Yangtze River have steep slopes to facilitate rainwater drainage; The walls of the house are very high, which is convenient for ventilation and heat dissipation. The roof slope of northern residential houses is small, even flat; Sitting facing south is convenient for lighting; The walls of the house are very thick, which can prevent wind and heat;

3. The courtyard wall connected with the basic buildings in the south of the Yangtze River forms a closed courtyard in order to adapt to the terrain, make full use of the spatial layout, be flexible and beautiful, and use materials reasonably;

4. Only a few painted houses such as chestnut, brown and gray are used in the free partition beam frame of Jiangnan residential buildings.
