1. The swimming pool belongs to special equipment and needs to be put on record. Is it illegal to build this on the terrace? Otherwise, it is not worthwhile to be demolished!

2. If there is no problem above, you can build it, but you need to know the bearing capacity of the balcony of this office building. This is the most critical, and this is the security issue. If the load is not enough, it needs reinforcement.

It is better to make an assembled swimming pool, which is convenient and safe.
