AJ100 practice Sheppard Robson has won planning approval for this £15million, zinc-clad rooftop pavilion on Aldwych House, London
Backed by developer Rowan, the scheme will add 790m² of office space to the existing 1926 building which sits within the Westminster Conservation Area .
According to the practice, the extension will rest on the building’s mansard roof and has been designed responds to the classical composition of the block’s main elevation.
Dan Burr, partner at Sheppard Robson, said: ‘This is an area of London where rooftop extensions are not commonplace and we’re delighted that our design convinced the committee that bold transformations of rooflines, which are designed with sensitivity and conviction, are a viable option.
‘Midtown is an exciting place to be working at the moment, with numerous schemes by world class-architects and major institutions like the LSE on the drawing board or beginning to take shape (see AJ 18.11.13).’
Since buying the building in December 2011, Rowan and GI Partners have already overseen a MoreySmith-designed overhaul of the reception area and atrium of the ten storey building.
The latest planning consent for the extra top floor and ‘wholesale refurbishment of the existing office space’ forms the second part of the redevelopment programme.
Once complete the total value of the building is expected to be in excess of £200million.
