EBBA have worked on the design of a new gallery space in Central London, transforming and extending a unique building to provide additional exhibition spaces and a cafe that connects to a mews street at ground level. The project is about improving the circulation and connection to the existing gallery while introducing a series of volumes that help to add well-proportioned spaces for the display of art. A lightweight linking structure helps to connect the new and old, while the solid mass of the building responds to the piece-meal qualities at the rear of the mews.
