Aldwych House roof top extension wins planning permission
25th September 2014
Sheppard Robson has been granted planning permission for a dramatic rooftop extension to Aldwych House, London, by Westminster City Council. The £15m project – situated within the Westminster Conservation Area – creates a bold design addition that rationalises the rooftop of this prominent London building with a dramatic pavilion-like structure, made up of a series of geometrical-folded forms.
The planning has been secured for London real estate company Rowan. The scheme – which was described as exemplary in the planning committee meeting – will add around 8,500 sq ftof high-quality office and reception space to the landmark 168,000 sq ft Midtown office building. The structure will be clad in zinc with carefully positioned glazing to frame views towards Southbank and the City, whilst also controlling solar gain.
The extension rests on building’s mansard roof, with the design improving the proportion of Aldwych House and making it consistent with neighbouring rooflines. Sheppard Robson’s design has been carefully considered so the new roof form responds to the classical composition of the building’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.
