Existing architectural elements of this historic Boston brownstone are incorporated into a new scheme that modernizes the space. Bathrooms are treated as independent volumes repeated on each of the four stories. The legibility of these volumes relies on rendering a corner of the bathroom as a glazed, partially eroded surface. This translucent corner acts as a "beacon" and allows natural light to pass through the space and into adjacent areas. Placement and design of beacons on each bathroom volume is slightly varied between stories; however, they are collectively illuminated through a single switch, which unifies the many floors into a single chamber of light. An oversized kitchen island consolidates perimeter surfaces and functions as a piece of storage furniture. The square-shaped island is composed of smaller rectangular volumes and is completed with a single slab of Green Danby marble. Considerate of the prevailing historic architectural details, the new baseboards coordinate existing floor heights with bathroom walls and existing trim.
