Bravo on the out-of-the-box thinking. Nice to see someone make such an opportunity happen, showing others that status quo need not be adhered to.

I once seriously considered buying a defunct health club for the same domestic purpose. Adapting the locker rooms seemed the most daunting aspect, but the 3-lane full-length indoor pool was awful tempting.

Notice how far out the family had to go to make it work: fully insulating walls, wood heat, and a large garden among other factors.
