SUSTAINABLE RETROFIT WITH NORDIC COPPER

Adaptive reuse of existing buildings is an essential strategy to reduce embodied carbon , while regenerating our urban environments . An exemplar of this approach – 72 Broadwick Street – is crowned by a profiled roofscape clad in Nordic Brown Light copper from Aurubis .
