Populus Hotel in downtown Denver looks less like a typical high-rise and more like a building shaped by nature.
Designed by Studio Gang and led by Jeanne Gang, the 265-room hotel takes its identity from one of Colorado’s most recognizable natural symbols: the aspen tree. Its name refers to Populus tremuloides, the quaking aspen, whose pale bark is marked by dark, eye-shaped scars left as the tree sheds its lower branches.
Those natural marks became the hotel’s defining architectural feature. Across the façade, windows of different sizes and shapes echo the “eyes” of aspen bark, turning the building into a sculptural landmark in the city.
But the design is not only visual. The windows are shaped with projecting “lids” that help shade the interiors and channel rainwater down the façade. At street level, some openings rise up to 30 feet, framing the lobby, restaurant, and public spaces. In the guest rooms above, the deep windows create places to sit, look out, and feel closer to the surrounding city and landscape.
Populus also reflects Studio Gang’s broader interest in architecture that responds to ecology. The building uses a compact triangular site, incorporates fly ash in its concrete structure to reduce cement use, and avoids dedicated on-site parking — an unusual move for a newly built hotel in downtown Denver.
The hotel has been promoted as Denver’s first carbon-positive hotel, with sustainability strategies including reduced embodied carbon, carbon credits, renewable operations, food-waste diversion, and nature-based initiatives. Because carbon-positive claims can be complex to verify, the strongest way to describe it is that Populus aims to go beyond net-zero rather than simply calling it a solved achievement.
Completed in 2024, Populus is more than a hotel with a striking façade. It is an example of how architecture can borrow from natural systems without simply imitating them — transforming the pattern of a tree into structure, shade, atmosphere, and identity.
In a city framed by mountains and forests, Studio Gang’s Populus turns the memory of an aspen grove into a new urban landmark.
