Why it's listed

Built in 1940-41 at 135 "A" Street in South Boston, this two-story garage served the U.S. Post Office as a vehicle maintenance and operations facility. Its trapezoidal concrete form has scored walls suggesting panels, streamlined curved corners, and large steel-sash windows with wire glass. The vehicle entrance is marked by sweeping curves and gilded aluminum lettering, the only applied ornament. A two-car ramp and a vehicle elevator with a tall penthouse are left visible as design elements. Gilbert Stanley Underwood, a West Coast modernist who consulted on federal projects, was the architect, and Grande & Volpe, Inc. was the contractor. The building was listed as a rare Boston-area example of the International style, reflecting a federal shift away from classical design toward a modern, functional approach. Alterations include a 1983 coat of yellow paint, some sealed skylights, added doors and fire stairs, and removal of a central column and island near 1960. It remains in postal use.

Significance in brief: The nomination argues it is a rare Boston-area example of the International style, even though it was less than fifty years old when nominated. Its functional planning, scored concrete panels, steel sash windows and exposed ramp and elevator reflect the federal government's move from classical tradition toward modernism. It is also a landmark in an industrial district of older brick buildings.

What listing means for this property

For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
