This week we revealed a stone high-rise in London

This week on Dezeen, we published Petra Heights, an innovative high-rise building in London with a stone exoskeleton, designed by Groupwork and Webb Yates.

The highly distinctive 10-storey building on Finchley Road in London is held up by a stone exoskeleton, which the team behind it called a world first.

Also in London, another building that experimented with construction technology, Richard and Su Roger's seminal 22 Parkside house, was "gifted to the nation".
