“This third level is all about having fun, socializing and just enjoying life,” explains Kirman. “It’s essentially a daylight basement with walls of glass and this incredible pool with just amazing views.

The home itself is surrounded on three sides by moat-style infinity-edge pools with massive decks for entertaining.
