Chicago's Garden in a City was held last week. We went on Friday and saw some inspiring landscaping ideas (more posts to come). This entry, from Chicago Speciality Gardens, was the official first place prizewinner. Entitled "The Living Rooftop Movement", it was inspired by the creative use of the city's rooftops for environmental and recreational purposes. The natural materials and simple spacial levels made it modern and luxurious.
