Net-Pool Café makes an intriguing reuse of former industrial infrastructure elements

In December 2010, the Yangshupu Power Plant in Shanghai, China officially closed and was transformed into public space. The space’s latest addition, the Net-Pool Café, makes intriguing reuse of net pools, which were part of a former industrial wastewater treatment system and leftover on the site. A new split-cone arch roof above makes reference to the circular form beneath and provides a spectacular shelter element.

Upon investigating the site, TJAD Original Design Studio found 24 pillar foundations, which are carried on two large circular bases with a diameter of 20-meters. These circular foundations now serve as a new floor for the sunken space.

The 18-lobed split-cone shells above are continuously connected to form a radial reinforced concrete split-cone arch shell structure in which horizontal thrusts between adjacent units are balanced.

A concrete ring beam with a diameter of 6m is added on top of the roof as well as a ring beam to the ground to balance the axial thrust of the whole shell. The result is a spectacularly light, column-free roof system.

The functional space beneath the new roof includes light meal preparation rooms, dining areas, and toilets. These functional spaces are divided into two types, one a transparent area enclosed by a glass curtain wall, and the other an area enclosed by aluminium partitions. The architects say the ultimate aim is to create a discrete, inspiring space for people to walk, wander, stop, and rest.
