Statement of Significance

Description of Historic Place

Building 406 is located within the self-contained community of Pleasantville on the north shore of Quidi Vidi Lake. It is a long, two-storey, flat-roofed, rectangular apartment building with low, horizontal massing and a white painted exterior. The designation is confined to the footprint of the building.

Heritage Value

Building 406 is a Recognized Federal Heritage Building because of its historical associations, and its architectural and environmental values.

Historical Value
Building 406, 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 is now owned by the Canadian government.

Architectural Value
Designed for the housing of troops, Building 406 is a very good example of a wartime wood and frame permanent structure that was conceived to be highly functional in design and construction. As a four-unit model, simple rectangular shapes and plain aesthetic elements are characteristic of its 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 406 maintains an unchanged relationship to its site and the surrounding structures. It also reinforces the 1940s character of the military base setting and is familiar to those living and working on the base.

Character-Defining Elements

The following character-defining elements of the Building 406 should be respected.

Its modern design and good quality materials and workmanship, for example:
- the scale and low massing of the long, rectangular structure;
- the flat roofs outlined by simple extended eaves;
- the projecting wings and stairwell blocks and each entrance emphasized by a concrete block canopy;
- the highly functional interior divided into four, four bedroom units;
- the white painted aluminium siding on the exterior walls and the size, form and spacing of the door and window openings.

The manner in which Building 406 maintains an unchanged relationship to its site, reinforces the military character of Pleasantville and is familiar to those working and working on the base, as evidenced by:
- its ongoing relationship to its site, and complex of buildings located within a suburban neighbourhood;
- the modern plain aesthetic of the utilitarian structure, which harmonizes with the cohesive grouping of the buildings, and creates a strong visual unity on the base;
- its role as an apartment building that makes it a familiar point of reference.
