Can I put the wooden house in the stacked yard?

You can put a simple pavilion instead of a wooden house.

Building wooden houses in the courtyard of stacked villas may infringe upon the rights and interests of other owners, and some buildings need urban construction approval, so it is suggested that pavilions can be built, but wooden houses cannot be built. You can also ask the owners for their opinions from top to bottom, and they all agree and sign and seal, or you can build it, and no one reports it.
