The living room is a place for all kinds of daily gatherings and the activity center of the family, so it should not be too exposed. In the current apartment design, many people can see the inside clearly when standing outside the door, which lacks secrecy. So the existence of the porch is very necessary. That is to say, there should be a buffer space after entering the door, and there should be a screen similar to the shadow wall, so that the line of sight outside the door can't be seen, and the gas at home will not leak out.
The entrance is a buffer zone between the gate and the living room, which plays a basic role in shielding. In the living room, you will feel much safer and not afraid of privacy exposure. If the gate faces northwest or due north, and it is often attacked by cold wind in winter, it is even more necessary to use the porch to cover it. Houses close to the ground are often easily penetrated by strong winds and dust outside. Setting the porch can prevent wind and dust and keep the room warm and clean.
