Building a swimming pool on top of the basement

[Mickcy]

I would like to thank you in advance for reading my post.

I would like to kindly request your advice on whether it would be possible to build a swimming pool on top of a basement. My basement is about 3m tall and I use it as a parking space; however it is enormous (80 square meters). On top of the basement is my garden connected to the back of the house. So what I am actually talking about in making a whole on the back of the garden (i.e. of the concrete) and insert the fiberglass swimming pool consequently scarifying (if required) some of the parking space. Is this possible? Dangers? Does it need support from below? Actually I can imagine that this kind of construction is something similar with building a pool on a block of apartments.
