The Willett Building, Chelsea
An important Grade II listed building in the Sloane Square Conservation area. This imposing landmark structure forms almost the entire south side of Sloane Square. The ground and basement floors are currently occupied by the flagship Hugo Boss store with high-end luxury apartment above.
This Portland Stone building was designed as an Anglicised version of the Beaux Arts classical Style by Edwardian architect E.W. Mountford in 1904. The building is named after William Willet and his family firm of builders who constructed the building. ‘Willett Building Services’ created a name for themselves in the luxury house market with designs influenced by the great Victorian architect Norman Shaw. Willett is also famed for creating ‘daylight saving’ and British Summer Time was introduced in 1916. Fascinated with light-making machines, his patented “Willett Petrol-Air-Gas Light Generator” showcased in the basement of the building.
Le Lay Architects were commissioned by the Cadogan estate to convert four apartments, each around 3000 Sq ft and the whole of the top floor into eight new apartments. We negotiated substantial gains in accommodation with the Planning Department as part of a larger strategic regeneration of the building.
