Five active kids, five bedrooms, almost 5,000 square feet, and unlimited creativity (and we're guessing an equally large budget). That was the starting point for this amazing New York City loft and Incorporated Architecture and Design, the company charged with turning the cavernous space into a kid-friendly, colorful, fun space. Mom in residence Kelly grew up in Santa Cruz, CA, and while she loves raising her kids in Battery Park, she wanted to re-create the front and backyard of her childhood — indoors. An urban treehouse, which cleverly incorporates Cole & Son's Woods wallpaper, a life-sized cartoon tree in a girls' room, and areas dedicated to climbing, playing, dancing, homework, piano, and more accomplish her dream in outrageous style.
