It is the project of Graham Hill, entrepreneur and treehugger.com founder, to come up with an ideal New York apartment—one with a small footprint, both physically and environmentally, and one that offers just as much beauty and functionality as a pad multiple times its size….. When you walk in, you encounter what is, at first glance, a small studio apartment. Within that cube are actually 8 functional spaces. The living room and office become the bedroom with a tug of a bookshelf. Open one of the closets and you’ll find 10 stackable chairs that go around a telescopic dining table for large dinner parties. An entire guest room with bunk-beds and a closet is revealed behind a wall that slides out on tracks. And of course, a well-equipped kitchen and bathroom await.
