The architectural and planning firm of Stull and Lee, Inc., established by Donald L. Stull in 1966, has made a profound impact on the physical environment and landscape of Boston. With co-partner David Less and a staff of 40 design professionals - architects, planners, and urban designers - Stull and Lee grew from residential design work to major building projects in educational, health care, correctional facilities, office and manufacturing facilities, transit station design, and a variety of urban design and planning commissions. Among the firm's designs are: Roxbury Community College, The Harriet Tubman Center, the town-square concept for the South Station concourse, and the new Ruggles Street (MBTA) station. The firm's Southwest Corridor Urban Design (a linear park running some 4.7 miles through the city) represents the first time in Boston that an architectural rather than an engineering firm has developed an outdoor landscape aesthetic.
