Most children have some kind of playhouse, whether it be a pink plastic eyesore or a magnificent three-level tree house (maybe that was just me), and even though we grow older there's still a small part of us that wants to maintain that playful feeling in our own home. The Residences at W Hollywood in Los Angeles must know that feeling well, because they chose interior designer Christopher Grubb to give one of their luxury urban penthouses a "playhouse" liveliness fit for a CEO's inner child. If you're thinking this would be a good place to tuck in for the night, think again because instead of a bed, the master suite has a custom gaming table!
