Achilles is the unique refurbishment of a terraced house in Hampstead, West London, resulting in a new tactile interior scheme contrasted by a distinct, monolithic extension that appears entirely hewn from marble. Designed to offer a seamless connection between a renewed ground floor plan and the south-east facing garden, the marble side extension introduces volume and light to the previously dark, disconnected living spaces of the Victorian home. The clients' brief called for a full house refurbishment with a functional, serene interior, improved circulation and storage, and flexible, spacious dining and entertaining space for hosting large gatherings. Achilles now features an improved entry sequence fitted with sleek storage, a new guest WC, and an open plan ground floor which steps down into a bright kitchen. A custom-designed island marks a central gathering point. The consistent use of marble throughout demarcates the kitchen as a calming space that appears slotted into place, connecting at highly detailed and considered junctions to the existing architecture.
