When outdoor space is limited, look up and see what space is available. This collection of 40 rooftop spaces shows what can be done with a flat spot on top and a bit of creativity. Lounging, swimming, entertaining, even growing food, are a few of the possibilities for these elevated outdoor spaces. So put your thinking cap on and start designing, because things are looking up for the great outdoors.
