The Spiral Wine Cellar. Because apparently heaven is reached by going south, from any room in your house! We're really obsessed with this. You thought there was barely enough space to add a washer/dryer, but apparently you can have a sprawling, swirling wine cellar. This might rival your closet as the coolest extension of the home, and will also contribute to not only endless parties, but the jaw-dropping awe and envy of your guests. Every hour would be happy hour.
