The balcony was closed during the renovation, and now the property has gone to the Planning Bureau ~ ~ ~

The property has no right to prevent you from sealing the balcony. The house is your property right, and the law protects private property. The property can only negotiate the style and color of the balcony with you for the beauty of the whole community, and you can't force you to dismantle it. Even if the property has regulations, when local regulations conflict with national laws, the national laws shall prevail. I believe that the Planning Bureau will not interfere in such a matter, because it is not within the jurisdiction of the Planning Bureau. A lot of similar things have happened in Beijing, and there are many mature cases for reference.

But as the owner, for the overall beauty of the environment, we should cooperate with the property in the style and color of the balcony. After all, the quality of the environment is related to every owner.
