ESA Architects has been awarded planning consent for its revamp of the listed 1960s Birdseye headquarters in Walton-on-Thames
ESA will replace the external cladding and refurbish the existing 17,000m² building. The firm will also replace a 1963 annex with a 10,000m² three-storey structure, forming a public court between the two buildings.
The proposals have received the backing of English Heritage.
ESA’s creative director Nic Sampson said: ‘The existing building remains a wonderful and inspiring example of post-war corporate architecture and represents an enormous challenge. Our new proposed addition is a sizeable building in its own right and had the difficult task of responding to and enhancing the existing strident architecture, but at the same time establishing a confident aesthetic of its own.’
