Hi Jane,

I've moved your post into a different part of the forum where hopefully it will get views and responses from the few people here who can answer your questions. I just wanted you to know that you aren't being ignored!!

Jane, are there no pool builders in Italy around where you live? They would probably be the best in knowing what the parameters are for building a pool there. They should also build it to your requests too, such as the floor returns.
Here's ONE site that may give you a start. http://www.inyopools.com/build_your_own_pool.aspx
