First of all, compared with the above-ground courtyard or terrace, the sunken courtyard is very different in landscape design, waterproof and drainage and later use. We can't simply say that the sunken courtyard is not good, but it is difficult for the courtyard that sinks more than 3 meters to play its due role. Of course, owners who buy villas and own courtyards rarely change their purchase decisions because the courtyards are sunken, not on the ground.

Secondly, how to design and build a sunken courtyard.

(1) Drainage

Under normal circumstances, the design and construction of the courtyard lags behind the indoor design and construction, so I would like to remind you that the drainage of the sunken courtyard must be fully considered and the elevation should be fully reserved. Prevent rainwater from being deposited indoors and in the hospital by accumulated water in the later period.

(2) Composition

This is not much different from the ground courtyard, mainly considering the beauty of function, transportation and rhythm. General composition rules apply to sunken courtyards. However, when considering the design, we should pay attention to the height difference between plants and structures, which can not affect indoor lighting. At the same time, in the relatively dark corner of the sunken courtyard, a practical space with hard landscape as the main part is designed, not a plant planting space.

(3) Elevation

This is where the sunken courtyard is different from the general courtyard. The three sides of the sunken courtyard are generally solid walls, which are highly uniform. The walls are not allowed to be hollowed out casually, which lacks the transparent aesthetic feeling of the ground fence. Therefore, the modeling, decoration and composition of the facade should not only be plane composition, but also echo and be symmetrical with the theme of the ground and landscape. Try to reduce the pressure of high walls on the room. It can be solved by three-dimensional greening or three-dimensional decoration.

(4) Materials

The decoration materials are light partition board and light composite wall board, which have the advantages of light weight, thin body, increased use area, short construction period, fire prevention, sound insulation, moisture prevention, environmental protection, earthquake resistance, strong stability, strong hanging force, direct slotting and pipe burying, and convenient installation and decoration. Suitable for all kinds of different buildings.

I hope that future generations can still see the green hills and smell the flowers.
