Is it reasonable to build a gazebo in my balcony less than 2 meters after the renovation of the second floor community?

It is unreasonable to build a gazebo on my balcony less than 2 meters after the renovation of the second floor community. The terrace on the second floor of the community cannot be used as a terrace. Because the terrace of the community belongs to a public place, its ownership belongs to the property, and the owner cannot occupy it privately. If you build it at will in the community, it will also destroy the environment of the community.
