The project describes a strategy which revitalizes the city through building in existing urban fabric. By finding the underutilized volumes in the dense city, and building in unused development rights, a building can exist in harmony with its surroundings without disruption. The proposal becomes a new kind of building, one that exists adjacent to and hovering over existing buildings, like a tight-fitting, three-dimensional puzzle. The aesthetics of the building represent this change in relation to context. It is a symbol of the virtual man-made lines of the city, plot lines and building height restrictions.
