South Crescent

The four-storey building on the corner of Central London's Tottenham Court Road and Store Street had been standing since 1905. A long-term relationship with Costain led to WGI undertaking a 'due diligence' study on the City of London's Stage D tender proposals for the property's redevelopment - and then to be part of the Costain's competitive tendering team.
The requirement was for a five-storey scheme of offices, residential and retail use. A major challenge was the retention of the existing façade and original features - with the design team deciding on a completely new structure, to enable larger, flexible floor plates. This ensured meeting contemporary standards, achieving acoustic separation, supporting the new two-storey glass-clad mansard structure, providing high thermal mass and reducing construction time.
The distinctive 4,800m2 West End headquarters building incorporates a new laminated and timber curved glass roof providing panoramic views of London. It optimises floor area and provides flexible space. WGI successfully collaborated with the City of London's architect in developing the design proposals for the £21 million project.
