Get to know us…
For nearly 50 years, Poss Architecture + Planning and Interior Design has been a leader in Aspen architecture and mountain modern design, delivering timeless, high-quality architecture and interiors across the Rocky Mountain region and beyond.
Our multidisciplinary team of architects and interior designers brings a depth of experience, creativity, and a collaborative approach to every project—whether it’s a luxury resort, a mixed-use development, or a custom residential retreat.
Known for our innovative and site-specific solutions, we specialize in bespoke designs that harmonize with their natural surroundings, reflecting the unique character of each location. With a commitment to professionalism, precision, and excellence, Poss has earned an international reputation as one of the best architecture and interior design firms in Colorado and the mountain West.
From initial concept to final construction, our mission is to create architectural and interior design solutions that are both beautiful and functional—tailored to each client’s site, vision, lifestyle, and budget. These principles remain the foundation of great design and long-lasting relationships with our clients, consultants, and communities.
Our Collaborators
Poss & the Community
At Poss community service is as foundational as our commitment to timeless, innovative design. Guided by a belief that great design extends beyond the built environment, the firm is deeply invested in supporting the people and places that surround our work. Our outreach efforts focus on youth, education, the arts, and environmental stewardship—values that align with our mission to create meaningful architecture that enriches lives.
From preserving Aspen’s architectural heritage to advancing sustainability in the Roaring Fork Valley and beyond, our team actively participates in causes that matter. Poss proudly supports a range of local and regional nonprofit organizations, including the Roaring Fork River Conservancy, The Buddy Program, Aspen Community Foundation, Habitat for Humanity, The Art Base, Basalt Education Foundation, Roaring Fork Leadership, Shining Star Foundation, and Home Health Care and Hospice of the Valley.
This spirit of giving back is woven into the culture at Poss—whether we’re designing luxury mountain homes, sustainable mixed-use developments, or boutique commercial spaces. Our commitment to community is just another way we build lasting relationships and leave a lasting legacy.
