Watertown Supply Co., Watertown, MA. The company consolidated its corporate office, wholesale sales, and warehouse into a new facility on Grove Street, Watertown. Located on a 1.1 acre triangular site adjacent to the Boston and Main Railroad, the parcel is within 200 feet of a two-family residential district. The client, Mr. William Tragakis, had taken over the plumbing and heating supply business from his father and expanded it from a small storefront location with satellite storage to the present centralized facility. The initial design challenge was to relate to Watertown’s rich industrial heritage, i.e., the nearby Watertown Arsenal with its vast shed structures, yet also blend in with the adjacent residential neighborhood of pitched roof two- family houses. The design utilizes a 112′ long x 25′ wide insulated shed-roof skylight system over the wholesale sales area for a bright space that showcases their quality products, and knits together the varying building elements. The skylight also provides natural illumination into the warehouse and upper level offices. Studies have shown that reduced electrical lighting offsets heat loss through the non-traditional roof.
