A reflection of values common to both modern and vernacular agricultural buildings, this sheep and hay storage barn in Plantagenet, Ontario is a highly rational and functional structure which uses the least amount of materials possible. The 10,000 s.f. building was constructed in 1979 for $2 per square foot.
Cantilevered, light-frame prefabricated wood trusses span the full width of the barn, sheltering a high central hayloft and low flanking sheep pens. Each 6 x 6 wood post on 4' centres along the central bay carries a single truss, avoiding the need for a spanning member at the primary bearing points. Columns are placed at 8' centres along the exterior walls, the maximum span for the 2" boards backing up the exterior sheathing. The primary load at the tail of the truss is uplift, so two 2 x 8s are sufficient to carry the trusses between posts
The barn is skinned with prefinished metal siding and galvanized metal roofing.
