Exactly because the new wing was to be an extension of the existing armshouses the museum has occupied for almost a century, we took many of our clues for this design from the existing buildings. The brick structures have a typical timber pitch, and we used London brick. But we chose to fill the space between the old and the new with a diagrid roof that swirled between the brick structures like a cloud. When visiting the museum, visitors pop out from a timeline of room sets only to discover that the rooms of the twentieth century are not organised as a line, but as a loop.
