As the museum prepares to leave its 70s home, plans to raze the site and build an office-led new complex have sparked a battle with those who want to repurpose what’s already there
The move raises the contentious question of what to do with the buildings on the site, by the elegant postwar modernists Powell and Moya, which include the old museum and a 17-storey office tower called Bastion House. The City of London – the local authority-cum-business enterprise that owns the site – wants to replace them with 780,000 square feet of offices and other uses. Residents of the Barbican and other objectors say this would be a wasteful and environmentally damaging overdevelopment of the site, contrary to the City’s own policies and proclamations about climate.
