That's a good idea, but you should consult the relevant management department first. If your children's playground has large electric equipment, it probably won't work. Because of the safety and noise, it is estimated that it will not pass. If you are on the open-air rooftop, you should consider the problem of wind and rain protection. If it is the roof of the community, it is even more impossible for you to run. That's a completely illegal building. .

Children's paradise is best to consider the storefront on the second floor. Mainly fire prevention, safety and noise reduction.

Please forgive me for speaking badly. I hope it will help the landlord. Thank you~
