Is the sunshine room of Xincheng Garden in Suzhou Industrial Park an illegal building?

Sunroom in Xincheng Garden is an illegal building.

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. Whether the terrace is privately owned by the owner 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 terrace is privately owned by the owner and there is no relevant regulation prohibiting construction, then if the owner wants to build a "sun room", it should also be built without affecting the lighting and use of others. If you want to repair or rebuild the existing building facilities, you must declare to the property, communicate with the property and developers, go to the relevant departments for approval, and apply to the Planning Bureau for filing.
