The A-frame might be America's most iconic ski house, but in 2015 you're more likely to find one being torn down than meticulously restored. No other architecture style so fully encompasses the optimism and funkiness of the 1960s and early 1970s. Take this just-listed gem in Big Bear, California, asking $234,500 for 3 bedrooms, 1 bathroom, and 1,172 square feet. The triangle structure ticks off all the A-frame requirements: part wannabe treehouse, part alpine abode with full-height living area and cozy sleeping loft. There's even the requisite rust-colored outdoor deck built for lounging in the treetops. Throw in the two-toned timber interiors, a marvelous striped carpeting that could also double as an Afghan blanket pattern, and the only bathroom's flower-power wallpaper, and you've got a relic of 1970s clichés. Sure, there's no bright yellow toilet or avocado counter, but we think the fireplace and matching brown-colored appliances will soothe the soul of any 70s diehard. With a bit of elbow grease, this classic A-frame could really shine.
