A steel table and a large cushion wrapped by an arbitrary net of steel cables do not only form a bus terminal but a functional art piece in the urban space. A borderless pattern of bubbles has been printed on the blue upper and the transparent lower ETFE-foil. The world’s largest inflated cushion has been built very airtight and energy efficient.

Integrated building services:
All pipes for roof drainage and air are invisibly integrated, as well as wiring and control and feedback systems into the steel structure. Hence, the roof is clean and at the same time visually complex and readable: Bottommost are the bus lane and the pillars, followed by the cable network and the clear membrane. Behind these are the table structure, the upper blue skin, and finally the upper wire ropes.
