It began with a dedication to reuse a building of substance and significance to create a project with a fresh and modern design. The original 4-story Pattern and Joiner Shop was built around a long, narrow storage yard used for the construction and storage of full-scale mock-ups of Naval designs. The strength of this original structure was maintained while the contemporary, saw-tooth construction of the new floors celebrates the riverfront and the area’s rich nautical history. The slender courtyard was opened up and made accessible through the addition of 3rd and 4th floor terraces, and on the lower floors, through the generous use of glass. The design integrates the building’s original features by exposing interior brick walls, columns and the original floor. Vertically expanding the windows and exposing the ceiling allowed for contemporary, light- filled loft units. Green roof components and recycled timber materials in the courtyard and on the terraces minimized environmental impact. As the first building erected in the 40-acre redevelopment of the Navy Yard, the design has been a catalyst spurring the revitalization and merging the old and the new.
