Statement of Significance

Description of Historic Place

Building 511 is located within the self-contained community of Pleasantville on the north shore of Quidi Vidi Lake. It is a long, one-storey, flat-roofed, rectangular structure with low, horizontal massing, and white painted exterior. The designation is confined to the footprint of the building.

Heritage Value

Building 511 is a Recognized Federal Heritage Building because of its historical associations, and its architectural and environmental values.

Historical Value
Building 511, as part of the former United States military base of Fort Pepperrell, is closely associated with the Second World War perimeter defence plan. This plan called for strategic continental outposts such as Newfoundland and Jamaica to be armed and fortified to prevent an attack on the United States. The base was vacated by the United States in the 1950s and now owned by the Canadian government.

Architectural Value
Designed for the housing of troops and their families, Building 511 is a very good example of a wartime wood and frame permanent structure that was conceived to be highly functional in design and construction. These four-unit apartment buildings are very similar in design to the other permanent apartment buildings and amongst the largest erected on the base. The simple rectangular shapes and plain aesthetic elements are characteristic of the modern style. Integral to the complex, the structure’s architectural significance lies in its contribution to the overall visual unity of this cohesive group of modernistic buildings.

Environmental Value
Building 511 maintains an unchanged relationship to its location, a flat, open site and reinforces the 1940s character of its military base setting. It is familiar to those who live and work in the area.

Character-Defining Elements

The following character-defining elements of the Building 511 should be respected.

Its modern design and good quality materials and workmanship, for example:
- the aesthetic characteristics which link it to the modern style, including the long, low profile of the building, the absence of applied ornamentation, the flat roof and the regular fenestration;
- the highly functional interior divided into four, four bedroom units;
- the white painted cladding on the exterior.

The manner in which Building 511 maintains an unchanged relationship to its open site, reinforces the military character of Pleasantville, and is familiar to those living and working on the base, as evidenced by:
- its relationship to its flat open unadorned site;
- the modern plain aesthetic of the utilitarian structure, which harmonizes with the cohesive group of buildings, and creates a strong visual unity on the base;
- the function as a family apartment building which makes it a familiar point of reference.
