Can the garden presented on the first floor be used as a sun room?

Generally speaking, it depends on whether the sun room is built illegally. First of all, it depends on whether the terrace occupied by the owner is owned by the owner. If it is owned by the owner, it is illegal whether the room is built or not. If the balcony is privately owned by the owner, it depends on whether there is a clause prohibiting the construction of "sun room" in the relevant treaty. If there are relevant provisions, then the owner can't build it.

If the balcony is privately owned by the owner and there is no relevant regulation prohibiting the construction, then if the owner wants to build a "sun room", he should also report it to the property, communicate with the property and developers, and go to the relevant departments for approval without affecting the lighting and use of others.
