Aldwych House, WC2 London, UK

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 scheme adds around 8,500ft² of high-quality office and reception space to the landmark 168,000ft² Midtown office building. The structure is clad in zinc with carefully positioned glazing to frame views towards Southbank and the City, whilst also controlling solar gain.
