About 7 Air Street

Completed in October 2015, 7 Air Street is a major part of the Crown Estate's Quadrant development off Regent Street. The building has achieved a BREEAM ‘Outstanding’ rating and is the first ‘Outstanding’ listed building assessed under BREEAM New Construction 2011 with a score of 94%. The project is the most sustainable historic building in the UK and is in the top 1% of all UK buildings.

The project brief was to redevelop two Grade II listed properties, formerly known as Quadrant House and 7–9 Air Street, whilst retaining their existing facades. The two buildings were unified into a single, upgraded office building with combined floor plates, a new roof extension, a new centralised core and an entrance with street presence.

A significant part of this intricate transformation involved the rationalisation of different floor levels between the two buildings. The result is that in certain spaces, intentionally impressive ceiling heights and dramatic changes in the floor levels have been created. The project also includes the removal of the top two storeys of the buildings and their complete reconstruction, which provides brand new, prime Piccadilly office space. The new 7th floor features inset bronze-clad balconies and a roof top terrace with views across London.

The building's location played a central role in the design process. Situated on the fringes of vibrant Soho and the more traditional Mayfair, 7 Air Street is both unconventional and very high quality. The double-height main entrance is knowingly impressive with a high-quality and ‘cool’ ambience, meanwhile the adjacent seating area is deliberately cosy and calm. A key feature of the entrance is the bronze fins with intricate art detailing, which has been commissioned to artist, Giulia Ricci. Ricci has also designed a sculptural bronze reception desk. Together with a unique hanging light sculpture by UVA the reception interiors blend luxury with a more personal, craftsman-like feel. All materials used are natural, receiving top green guide ratings.

The building will emit 40% less carbon than the equivalent new build. It plugs into the adjacent energy centre in Quadrant 3, which incorporates two CHP’s and the largest and most efficient fuel cell in Europe. The roof hosts 100m2 of high efficiency photovoltaic panels, which are surrounded by 170m2 of intensive green roof with 16 species of native flora forming part of the Wild West End green corridor from Regents to St James’s Park.
