An "A-frame" is a type of architectural structure characterized by its triangular shape, resembling the letter "A." This design typically features two sloping sides that meet at the top, creating a peak. A-frames are often used in residential homes, cabins, and vacation properties, as they provide excellent stability and can efficiently shed snow and rain. The A-frame design allows for open interior spaces, maximizing natural light and ventilation. This style is popular in mountainous or wooded areas, where it blends well with the surrounding environment. A-frames can be constructed from various materials, including wood and metal, making them versatile for different climates and aesthetics.
