What are the advantages and disadvantages of Hefei duplex building?

Advantages: the vacant living room highlights the dignity: the general duplex building is a flat superposition of two floors, and the upper and lower floors are only connected by stairs. But now there are many vacant living rooms in the market, which makes the upstairs and downstairs effectively integrated, which is more conducive to the communication between family members, and also makes the room have a certain height difference, forming a rare three-dimensional space, showing a noble and atmospheric. Generally, the vacant part of the duplex room accounts for half of the living room area at most, which is also conducive to the lighting and ventilation effect on the first floor, and the rest can be used as a rest area. This design is more humanized and life-oriented.

Disadvantages: 1, poor natural ventilation and lighting.

Duplex residence has a wide area and a small depth. If the corridor-style plane combination is adopted, it will inevitably lead to poor orientation of some units.

2. Height restrictions

Duplex residence is not really a "second floor". So dividing the space into upper and lower floors will inevitably affect the height of these two floors. Although the static and dynamic are separated, the storage space is also large, but these are at the expense of floor height.

3. Staircase takes up space, which will be a little wasteful.

The stairwell may occupy 10- 15 square meters. Of course, there is another problem. If the flat floor is not well designed, the corridor will take up space. Relatively speaking, duplication wastes more.
