It's subjective to judge the negatives of A-frame cabins. A-frame buildings, with their pitched rooflines are great in snowy climates because they don't have to be subject to snow accumulation which could pose a threat to roofs. The roof of an A frame cabin extends far into the sides, close to the foundation level, and then creates two walls with a slope inside the cabin. A-frame cabins often have more than one floor and are loft-style due to their high ceilings.
