The folded facade consists of two layers. The outer one is a glazed skin made up of framed glass set in a tubular frame while the inner layer is the building’s windows. There are two major benefits to the design: noise from the busy boulevard is noticeably reduced and solar heat gain is decreased via radiation reduction and a breathable wall system.

In addition to the increased energy efficiency afforded by the double skin, the building holds meetings in a daylit, two story atrium that opens to a roof deck. To promote denser land use, the seven stories below roof contain office space and a subterranean three floor robotic parking lot.
