German designers Folke Koebberling and Martin Kaltwasser saved a fortune by using waste wood to create the gallery in the Cambridgeshire countryside.
Volunteers helped to build the two-storey octagonal space in just six weeks using old doors, windows, furniture and school desks donated by the local community.
"We're very proud of the gallery. It's the first building we've made totally out of garbage and has cost next to nothing to make," said Folke.
"It looks like a mix between a barn, a cathedral and a monastery."
The gallery, which they have named Amphis, lies just outside Cambridge and will be used to display art projects and show film screenings.
Timber, including 500 pallets, was contributed by locals and more than 40 volunteers helped to turn the rubbish into the building, which comes complete with a greenhouse conservatory.
"All the materials they used were either donated or found and would otherwise have gone into land fill," said Donna Lynas, director of Wysing. "I think people are keen to recycle and see their rubbish put to good use.
"This is an impressive two-storey building which could easily be adapted for someone to live in and shows just what can be built out of rubbish."
The gallery has planning permission for the next two years and the team eventually plan to fit a bathroom. (Ananova.com)
