80 Grosvenor Street is a new build mixed use development in the heart of Mayfair. Located at an important junction with Bourdon Street, and the widening of Grosvenor Street, the site gives the building its unique offer, uninterrupted views, west along Grosvenor Street towards Grosvenor Square.
The sensitivity of the site required, with the advice of the local authority, significant refinement of the proposals to develop a scholarly approach to the reinstatement, in Suffolk white reclaimed brickwork, and part retention of the Grosvenor Street elevation. This also incorporated a new, but classically detailed, Portland stone portico and bottle balustrade to define the office entrance. The retail entrance, on axis with Avery Row to the west, is marked by a more restrained Portland Stone elevation above.
The retention and reinstatement of the Grosvenor Street elevation determines the constraints for the office floors behind and the design discreetly sculpts a five-storey development out of an aggregation and extension of the three, long lost, townhouses that once occupied the site.
The building sets back to provide a terrace to the 4th floor office and a further terrace at 5th floor allowed us to optimise the amount of area that could be added without being visible in any of the planners identified strategic views.
The eastern and southern elevations are two formal exercises in rigorous brickwork design. Using different bonds and recesses they provide more contemporary, but contextual designs to these locations.
80 Grosvenor Street has always historically extended over Bourdon Street and with the redevelopment of the site we took the opportunity to extend the upper floor plates further to the south, but also to widen this underpass which is an entrance to the art district of Grosvenor Hill. This design move provides a unique viewing experience for a bespoke Albert Oehlen mosaic tile artwork, to be equally enjoyed from inside the office reception and the passing members of the public.
The reception, landlord common areas and amenity spaces are designed in a minimalist and restrained palette of marble, stainless steel, leather, and walnut. The design of these spaces was by GC Office with Orms collaborating on the detailing and delivery of their vision.
