After more than a decade of planning, an overlooked side of the ski haven of Aspen, Colorado, will soon be revamped into a new base village.
Named Chalet Alpina and covering two-and-a-half city blocks, the development will build a new modern ski lift that is closer to the city’s downtown and flank it with a luxury hotel and residences, a restaurant and ski museum inside relocated historic chalet buildings, and a broad new public plaza.
The project, which broke ground last fall, is situated at the loading point of the 1937 tow line that was the city’s first mechanized route up the mountain. Remnants of the steel lift that replaced it a decade later will be preserved as part of the project. With cost estimates totaling nearly $350 million and an expected completion in 2029, the 200,000-square-foot project will “fundamentally change” Aspen Mountain, according to a local official.
Jason Grosfeld, CEO of Irongate Group, the project’s lead developer, says the change is much needed and will provide skiers a more accessible alternative to Aspen’s existing ski base village, known as the Little Nell site. “That’s been built out for years. It’s wonderful, it’s great. People love it,” he says. The side of the mountain where he’s developing Chalet Alpina, however, “has been a little bit forgotten,” he notes.
As the site of the city’s first ski lift, this area certainly had a heyday, but Grosfeld says a decision in the 1970s to build a replacement lift that required skiers to walk a bit higher up the mountain to get on board pushed more activity to the Little Nell side. “That was sort of the beginning of the end of this area. In fact, in the ’50s and ’60s and even a little later than that, this area was actually pretty vibrant,” Grosfeld says.
He sees the Chalet Alpina project as a chance to breathe life into this side of the mountain. “I’ve been skiing in in Aspen since I was about seven or eight years old,” he says. “I am incredibly nostalgic about what skiing did for my childhood and my kids’ childhood, and what it still does for me. And so I really did want to bring that back.”
A close vote and a decade of development
Set in one of the most prestigious and expensive ski resort towns in the U.S., the project has endured a lengthy approval process and no shortage of opposition from developer-weary locals. Plans first started taking shape in the early 2010s, and Grosfeld says the project was shaped by extensive community outreach. A 2019 public vote on the project passed by 0.8%, a margin of just 26 votes.
The slow motion is partly due to the project’s unique makeup. It’s technically a complex combination of land parcels owned by Irongate Group and local developer HayMax Capital, the Aspen Skiing Company, the City of Aspen, and the luxury hotel company Aman Group, all of which had to collaborate to lay out a plan for the project, while also appeasing locals. Permits for the project began to solidify in 2023 and the project was cleared for construction in 2025.
“It’s been over a decade since we started this and it’s been really, really time consuming, and really difficult, but also really, really meaningful,” Grosfeld says. “Many developers don’t get that opportunity in a lifetime. So we’re super lucky and we’re treating the opportunity with the care and attention that it deserves.”
Callbacks to the past, designed for the present
Working from the beginning of the project with New York-based Guerin Glass Architects, Grosfeld says the project was deeply shaped by the historic nature of the site, including the 1940s-era steel chair lift structure that will be preserved, as well as the two mid-century chalet buildings that are being relocated and retrofitted. (One will be turned into a restaurant; the other into a ski museum, in partnership with the Aspen Historical Society.)
Scott Glass, cofounder of Guerin Glass Architects, says elements of these historic structures helped shape the new project, both in the forms of the buildings and in their details. “First and foremost, we wanted to be really intentional about the way the building sits on the site and how it cascades down the hill,” he says. “It doesn’t get too big in any single place, and it really feels like it’s part of the slope.”
The design team pulled on other elements of the surroundings, right down to some board formed retaining walls put in place back in the 1940s, which they then used to inform the look of various walls, planters, and even the ski hut at the base of the extended ski lift.
It’s all in service of blending the project into the city and the mountain. After all, a ski run splices right through the project’s site, making it a gateway to a new Aspen base village. “For us, one of the real treats and important elements of the project is the public nature of everything,” Glass says. “It’s a resort hospitality project, but it’s also a ski museum and a portal to one of the more important elements of the town.”
Some of these details have had more than a decade to coalesce. Grosfeld says that drawn out timeline, grueling as it may have felt at times, ultimately made the entire project better. “The nice thing about a long process is we get to stare at this thing for like 10 years before we’ve even built it,” he says. “We’ve been staring at these renderings for a long, long time and nobody’s sick of them yet. I can’t say that for every rendering that I’ve stared at for a long time.”
