Inhabitat is my go-to place for gorgeous, innovative, ecologically sound design, at least when I am planning for a future multi-millionaire version of myself, and I was delighted this week to discover, via them, the submersible swimming pool. When you want to swim, it’s a pool; when you need an extra room, you disappear the pool and get an elegant stone floor in its place. What I especially like about it is that it looks quite a lot like something out of Harry Potter (you will have to visit the website to see the full effect). This is top of the list for features in my fantasy home, alongside the cassette lamp and the toilet that you wash your hands in.
Glad All Over 
when I was at school, we had a swimming pool which, in the winter, developed a parquet flooring cover and was our assembly hall. Not an instant transformation – it took most of the Easter hols to accomplish – but a neat idea.There is nothing new etc….
They do it in It’s A Wonderful Life, too, but it doesn’t look so much fun there.
Some really wonderful posts on this website , thankyou for contribution.
