- Recreational Practicality: The steep roof effortlessly shed snow and rain, making A-frames the go-to choice for mountain ski chalets and lakeside cottages.
Pioneering Architects and Defining Examples
While kit homes democratized the style, architects explored its potential earlier. Rudolph Schindler’s 1934 Bennati House in Lake Arrowhead, California, is a key precursor. Later, architects like Andrew Geller became famous for their playful and influential beach house A-frame designs.
The Inevitable Decline
By the late 1970s/early 1980s, the initial A-frame fever cooled. Factors included:
- Shifting Tastes: A move towards larger, more conventional, and often ostentatious housing styles (the dawn of the McMansion era).
- Perceived Spatial Limitations: The sloped walls, while dramatic, created challenging interior spaces, limiting furniture placement and usable square footage, especially in less thoughtfully designed examples.
- Energy Concerns: Early A-frames, often built with minimal insulation, could be costly to heat, especially during the energy crises of the 70s.
- Market Forces: Mass-produced suburban homes began offering more square footage per dollar for primary residences.
