Mayfair Apartment, Upper Grosvenor Street

City of Westminster, London W1

Extensive refurbishment and fitting out work on this two bedroom flat located within a mansion block in Mayfair was completed in 2018.

The work consisted of the complete demolition and stripping out of the internal partitions and fabric and the reconstruction of the interior to a new layout. Our design required carefully working with the constraints of existing services and structural elements within the flat to provide two double bedrooms, an en-suite bathroom, shower room, kitchen and a generously proportioned reception and dining room.

The extensive mechanical, electrical and audio-visual installations are carefully integrated within our design in a discrete and sensitive way, by, for example, incorporating these services within the joinery design. This included existing communal services running through the flat that were discovered during the demolition and strip out phases.

Our design for the fit-out and selection of finishes was in response to our client's desire for a contemporary interpretation of an Art-Deco style that complements the original mansion block building, including the common parts from which the flat is accessed.

The interior design work was carried out by us and included the design of purpose made joinery, kitchen, bathrooms, doors, and the selection of finishes and floor patterns, blinds and fabrics with the clients to ensure a coherent and calm style throughout.

Our services included outline design, application to the Grosvenor Estates for Landlord approvals, detail design, interior design, tender action and administration of the building contract through to completion of the works.
