Have you ever biked around buildings like this? Architecture and design firm JDS Architects created the stunning Chongming Bicycle Park for a competition proposal. Called an"urban oasis,"it consists of a museum, visitor center and multi-purpose hall. The flagship attraction is a double helix museum that encourages visitors to ride their bikes down the exterior ramp. In addition, the multi-purpose hall is like a"hilly island"with a network of intertwining undulating ramps and terraces that visitors can either walk or ride their bikes down.
