Luxury Residential Architecture, Interior Design & Construction

Great homes are never accidental.

Great homes are shaped by early decisions, the right team, and a deep understanding of the people, routines, and moments that make a house feel like a home.

Duet aligns interior design, architecture, construction, and home stewardship within one integrated ecosystem. Each discipline has its own role, with decisions considered early and carried through each phase.

Through Duet Design, Duet Forma, Duet Build, and Duet Edit, our team supports the full life of a home, from early planning through construction and ongoing care.

Creating a home shaped around the people who live there, the life unfolding inside, and the details that give a place a character of its own.

Our Services

The Duet Ecosystem

Interior design, architecture, construction, and home stewardship each shape the way a home is planned, built, and lived in.

Duet Design, Duet Forma, Duet Build, and Duet Edit operate as distinct disciplines within one ecosystem. When decisions are considered early, the process becomes clearer and the home becomes more cohesive.

This structure allows each service to stand on its own while still supporting the whole. From first ideas through ongoing care, the work stays connected to the people, priorities, and details that define the home.

Leadership & Vision

Duet is led by Devon Tobin and Caleb Tobin, whose combined backgrounds in interior design, architecture, and construction shape the firm’s integrated approach to residential projects.

Devon founded Duet Design in 2011 and leads the studio’s work in residential interiors. Her approach is grounded in how clients want to live, guiding design decisions that feel intuitive, personal, and highly considered. That same perspective informs Duet Edit, where the focus shifts to how homes are maintained, organized, and supported over time.

Caleb leads Duet Build and Duet Forma, aligning architecture, construction, and planning early in the process. His background in both architecture and construction brings clarity to project coordination and execution.

Together, Devon and Caleb guide the Duet ecosystem, helping architecture, interior design, and construction move forward with greater alignment from the beginning.

Client Reviews

Why Colorado Homeowners Trust Duet.

“What really stands out is how thoughtful and well-structured their process is, while still feeling personal and collaborative. They take the time to understand how you live day to day and what matters most, then build the design around that. You can tell there’s real intention behind everything they do.”

“What sets Duet Design apart is their ability to create bespoke interiors that transcend regional design norms and stereotypes. Their work rivals the level of artistry, imagination, and sophistication typically seen on the East and West coasts, yet it’s available here in Colorado. We value their unparalleled dedication to artistry and precision.”

“Duet was able to get inside our heads and interpret our vision for our home, bringing it to life. The design process was made simple because we knew we didn’t have to worry about every decision. They understood our likes, dislikes, and what we wanted, and Devon and her team did all the heavy lifting, easing the burden of decision making on our end.”

“Devon has an incredible eye and is a great leader and mentor for her team of designers. We have had such a collaborative working relationship over the years, and Devon is full of ideas and very professional and productive.”

“People always ask about my house. The elevated experience, the attention to our aesthetic, while bringing new ideas to complement and create a home we are proud of are what sets Duet apart. Thank you for creating a space we love to live in.”

“This design team is focused as they create a unique design specific to the client’s personality and specific needs. This is an extremely talented team that I would recommend to anybody.”

“They’ve built a system that brings clarity to what can otherwise feel overwhelming, especially with a large project. Everything feels organized, well communicated, and tailored to you, without ever feeling rigid.”

“We wouldn’t have opted to do a custom build if it weren’t for Devon. There are simply too many decisions—too many places where things can go wrong—to do a custom-build without a confident vision. Enter Duet: They did a wonderful job of combining [my wife’s and my distinct] styles into a design that we both love for the entire home.”

“They are masters at getting inside their clients’ heads to create designs that truly reflect their tastes and preferences. In a world where a lot of home design looks the same, they make the effort to create one-of-a-kind spaces that honor the folks living in them. They design rooms that not only look amazing but are functional and easy to live in.”

“The rave reviews of their contemporary design work extended beyond myself. I sold my condo within 2 days, likely due to the incredible quality of work I received from Duet ideas, designs and construction implementation. To this day, it remains the coolest condo at the Denver Dry Condominiums.”

“From brainstorming and vision boards to the final reveal, this experience has been fun, exciting, collaborative and, from the client perspective, a breeze. Upon the first steps, the house we moved into immediately felt like a home and we owe all that to the incredible Duet Design Group team.”

“This was our second time using Duet. They really have a way of making spaces look exceptionally unique. My wife and I have pretty different styles, and Duet pulled it off spectacularly.”

“Duet exceeded our expectations (which were already fairly high), on time and on budget. Devon knows what she is doing, as does her entire staff. We were amazed by how well they figured out what we would like and how they pulled together comprehensive designs that we fell in love with when we saw them executed (and we’re pretty picky.)”

“Working with Duet Design Group was an absolute pleasure from start to finish. After selecting images of what I liked and then looking through fabric samples, they were able to nail it regarding my style and colors. Jump forward several months, and I was presented with a home that far exceeded my expectations. I would recommend Duet Design Group to anyone who wants their vision realized!”

“We were on vacation when Duet Design completed the installation [of all design elements to our 1935 Tudor], and we returned to a stunning, beautiful, warm home. We are delighted with the final result, and highly recommend Duet Design for anyone looking to transform a house into a home!”
