Luxury Interior Design in Boulder.

Duet Design Group has been one of Colorado’s most desirable interior design firms for more than 15 years, celebrated for luxurious interiors tailored to each client’s lifestyle, goals, and preferences.

Our team loves to work for Boulder clients, who are often eager to respond to the area’s distinctive topography and personality when building or remodeling their homes or offices. Boulder’s proximity
to the Flatirons and the area’s beautiful city planning—as well as its many historic homes and buildings—give Duet’s designers a shot of unique inspiration.

We’re excited to partner with many of Boulder’s most talented architects and builders. Together, we craft high-end projects that respond to the city’s surroundings and deliver on clients’ distinctive preferences and definitions of beautiful interiors.

Interior Design Services in Boulder.

Duet Design Group works across the Front Range, from Boulder to Colorado Springs and into the state’s mountain resort towns. Our portfolio of interior-design projects demonstrates the ways we meet and exceed each client’s expectations.

Duet Design nailed our style and the final product was simply amazing! It’s pretty incredible how they were able to utilize a questionnaire, a fabric quiz, and general observations about how we live to create a warm and inviting, yet cohesive and unique home that is reflective of us. And not only are they great with design and style; they run an efficient, client-focused business: (1) organized and communicative – Duet provides a high level timeline at the start of the process, and they stick to it! They stay on top of situations as they arise and communicate updates in a timely manner; (2) excellent service – solutions-oriented with thoughtful responses to any questions, and always willing to go the extra mile; (3) excellent relationships with vendors who know their craft well – the teams they bring into your home are professional, courteous, respectful, and efficient. We would highly recommend Duet Design!
