1 Berkeley Street – Reuse Projects – Allford Hall Monaghan Morris

Berkeley Street creates a vibrant 210,000 square feet mixed-use development containing offices, retail and the first 1 Hotel outside north America. Located opposite The Ritz Hotel on Piccadilly, this project involves the re-use of two 1970s buildings, retaining 90% of the existing frame, and façade elements along the two main elevations and expanding with three new extensions: a two-storey rooftop extension, new pavilion at the corner of Dover Street, and a small annex building within Dover Yard.

The extension at the corner of Piccadilly and Dover Street reinstates the historic building line and provides an updated identity to this prominent corner, with contemporary Portland Stone elevations engaged with those of the adjacent existing façade. Coupled with a refined two-storey extension to the upper levels, these extensions rejuvenate the somewhat dour existing facades whilst building upon the existing grain of the site, providing much-needed enhancement to both the performance and aesthetics of the current buildings.

Dover Yard, a new publicly accessible garden courtyard for building users and incidental commuters alike has been created within the site. Transforming what was an at-grade carpark and delivery yard, this new space maintains an existing public route and is enlivened by hotel and retail spaces at its fringe. A new annex building forms a fourth side to the courtyard, and provides offices for our client, Crosstree.
