69 Grosvenor Street 

Location: 69 Grosvenor Street, London


Client: Grosvenor


Status: Completed 


Size: 2,260 sq m

ESA architects have completed 69 Grosvenor Street, a six storey period ‘townhouse’ in Mayfair.

As well as the stuccoed frontage to Grosvenor Street, the building also has a composed frontage to the rear of Grosvenor Hill. The building is unlisted and sits within the Mayfair Conservation Area.


The proposals were mainly for the interior of the buildings, the inner courtyard buildings and the

courtyard itself. The works kept within the existing massing with the exception of a small extension to the inner courtyard buildings, to help rationalise the internal environment.


The inner courtyard was in a poor, incoherent state, thus it has been demolished and infilled

with a new glass ‘link’ building with a new glass roof light to bring light into the refurbished

basement areas.


The project aims to introduce a new concept of ‘boutique’ offices fit for such a prestigious location.
