According to the floor plan predicted by the subject, there are two families on the third floor, so they are not their own houses.
Give advice directly. The layout of stairs is designed according to the decoration scheme. The decoration plan is in the back.
The main structure of building materials is reinforced concrete. According to my experience, steel bars are seldom used in rural buildings. It is suggested that the main body consider adding more steel bars.
The layout should be considered according to the position of the load-bearing wall or column in the scheme designed by yourself.
I think the design of self-built houses is more free than that of urban commercial houses. It is best to optimize the design according to your own ideas and themes.
The first scheme is simple and practical.
This scheme is very simple, that is, how to use it is convenient.
It is recommended to set the stairs on the side. After all, there are three families. But according to my experience of stairs, many rural buildings are relatively simple, which is not very convenient for families with children. If you want to build a better one, you can refer to the setting of the duplex building.
Another point is that it is too wasteful to leave 300 square meters of space directly on the first floor. It is suggested that the subject make rational use of it.
The second scheme can refer to Beijing Siheyuan.
That is to optimize the flowers, birds, fish and insects in the yard and improve the quality of life.
