With an eye-popping exterior design (its jagged collection of slit-shaped windows on an all-white 13-story building is meant to evoke the Colorado state tree, the aspen), this boutique hotel goes all in on the environment: everything about its thoughtfully curated design is nature-focused, from the natural textiles to the forest sounds on the elevator speakers, while its biggest flex is that it aims to be the first carbon-positive hotel in the country. Public spaces are meant to mirror a forest floor, with the lobby and second-floor gathering spaces composed of varying wood shades and earthy art installations like a draped mycelium fabric above the first-floor bar. Upon exiting the elevator to the guest floors, visitors meet a darkened hallway meant to mimic the inner workings of a tree canopy, but the guest rooms themselves are all light thanks to the aforementioned geometric windows. Much of the furniture is upcycled and/or locally sourced, and the rooms are decked out in calming muted tones and pressed local wildflower art prints; beds are comfortable, toiletries are luxe, and about a third of the rooms have built in hammock-like benches to enjoy the windows and views. The ground-floor restaurant and bar, Pasque, serves elevated American cuisine with strong Colorado flavors for all three meals and the lobby coffee bar, Little Owl, offers pastries and locally roasted coffee. The culinary highlight is the rooftop bar and restaurant, Stellar Jay, which offers a similar menu to Pasque but with a wood-fired twist, along with creative cocktails and unbeatable views of the State Capital and surrounding neighborhood. All of this would be impressive on its own, but Populus takes it a step further with its focus on sustainability. Nearly all the disposable material in public spaces and guest rooms is compostable, there’s an on-site biodigester designed to ensure all food waste created is composted, and the hotel promises to plant a tree for every night every guest stays (achieving the coveted goal of becoming carbon positive).
