Part play pavilion, part events hall, this converted garage in Seattle goes all out for the kids and parents. There are monkey bars, ropes and various swings; hammocks provide the perfect place for reading or simply letting the mind wander; and a small bathroom and utility sink are nearby, making cleanup after parties and gatherings a breeze. The room can easily be converted from a gym to a party room, hosting a small dinner party or a family movie night for the kids' besties — and their parents, too.
