The long-running redevelopment battle that has come up against widespread opposition will now see the retailer table plans to appease its detractors. M&S has pledged that 95% of the materials in its existing building will be recovered, recycled or reused to ‘promote circular economy principles’.  Opponents say the scheme, designed by the architecture firm Pilbrow & Partners, would release almost 40,000 tonnes of carbon into the atmosphere. Campaigners from Save Britain’s Heritage also plan to argue that the building can be retro-fitted rather than completely razed. But M&S says the store has ‘asbestos throughout,’ and wants to create a new 10-storey building, with office spaces. M&S, also said the new building would use less than a quarter of the energy of the current structure on completion.
