circUlar Hall - Green Ring, Mannheim

The existing U-Hall is the heart of the BUGA. A green ring floats above it as a landmark visible from afar.
It is a living sculpture that stands for sustainable recycling management, the willingness to experiment and a spirit of optimism.

This circularly conceived tree hall, brought into the vertical, is not only part of the exhibition, but also a break in the tour and a place for the best views over the entire site. The tree house, built from recycled building materials, provides a habitat for flora and fauna, exhibition opportunities for field research and allows views of the solar power plant on the U-hall. Thus the ring is the central location of the U-Hall. This is where the tours and guided tours start, where people meet and where smaller and larger events take place.
