Aframes

Aframes, or A-frame houses, are a type of residential architecture defined by a steeply pitched roof that forms an A-shaped silhouette from the foundation to the apex. The triangular roofline is typically symmetric and extends to or near the ground, creating a continuous frame that supports all loads. Interiors are often open with a high central space and a loft or mezzanine above.

A-frames commonly feature large end-wall windows to maximize daylight and views, and interiors tend to place living areas on the ground floor with sleeping or storage lofts above. The design is well suited to snowy climates because the steep roof sheds snow efficiently and reduces wind and load on the structure. Construction typically uses timber framing with wood siding or other claddings, though variants may employ steel or masonry for bases. The form lends itself to compact, cost-effective building and can be adapted to vacation cottages, retreats, or resort architecture.

Variants include the classic A-frame and Modified A-frame, which adds vertical walls at the base to recover usable floor space and to improve interior layout and window placement. Insulation, ventilation, and moisture management are important, as the triangular envelope can create thermal and condensation challenges. Roof maintenance is also a consideration due to the steep slopes.

Historical note: A-frames rose to prominence in mid-20th-century North America as vacation homes and ski lodges, valued for simple construction and distinctive aesthetic. They remain in use today in rural or alpine settings and have inspired contemporary reinterpretations in modular and prefab building.
