Designed to look like an urban mountain, the Urban Forest Tower concept from MAD Architects brings a little of the wild into the city. Its more than 70 floors are comprised of eclectic and undulating shapes and feature floor-to-ceiling windows. The unusual shapes of the building’s levels allow wrap-around garden patios to thrive in the sunlight. The design is meant to combine the city and the wilderness, and it does bring to mind a wild mountain terrain.
