You’ll want to pack your best color-block ski suit before checking into Winter Park’s newest choice for lodging, the A-Frame Club, because although the insides of its 31 triangular little cabins are full of modern amenities, the outsides are decidedly retro.

“The vibe we’re going for is that 1970s, old Colorado ski culture mixed with a little European après flair,” says Adam Larkey, the chief operating officer at Zeppelin Development, the Denver-based firm that built trendy projects like The Source Hotel and Market Hall, Taxi and Zeppelin Station, and is now breaking into the high country hotel sector.

A-frames were a common sight in the 1950s, ’60s an ’70s in Colorado when they filled out ski towns and mountain resorts. Cheap and easy to build, the A shape also allowed snow to slide off the steeply-pitched roofs, said Amir Ameri, a professor at the University of Colorado Denver’s College of Architecture and Planning, adding that they were first used in Switzerland.

“I think the appeal of A-frames, above anything else, is that the imagery is one that’s associated with leisure time,” he added. Cute in their simplicity, they dial up nostalgia to a post-WW II era of prosperity when Americans started buying weekend homes near lakes, mountains and forests.

It’s true: A-Frames are made for charming mountain vacations, with their steep roofs pointing at blue winter skies and large windows letting in the alpenglow. But the buildings also fit squarely (or, rather, triangularly) into a broader travel trend: A-frames have been trending on vacation booking platforms like Airbnb for the last several years as the tiny home trend meets mid-century mania.

Think an A-frame cabin with a lofted bedroom that’s anchored by a colorful Malm fireplace and accented with cedarwood panels and a globe floor lamp. Then, throw in some trail maps and magazines that have a rounded Cooper typeface to hint they’re from a groovier era.
