Luxury Residential Architecture

Architecture that aligns design, construction, and how a home is lived in.

Duet Forma provides residential architecture within the Duet ecosystem, developing architectural solutions that shape how spaces function, flow, and perform over time.

Working alongside designers, builders, and consultants from the earliest stages of a project, Forma helps ensure architecture, interior planning, and construction remain aligned, creating spaces that perform beautifully in daily life, not just on paper.

Why clients turn to Duet Forma.

ARCHITECTURE DESIGNED FROM THE INSIDE OUT

Architecture and interior design approach space from different directions. Architecture often begins with structure and massing, while interior planning begins with how a space will actually be used.

When both perspectives are considered early, the program becomes clearer and the resulting spaces function far more thoughtfully.

ALIGNMENT BEFORE CONSTRUCTION

Early collaboration ensures architectural design, interior planning, and construction strategy evolve together before building begins, reducing costly revisions later in the process.

COLLABORATIVE BY DESIGN

Duet Forma collaborates with designers, builders, engineers, and consultants throughout the design process. This integrated approach helps maintain clarity and alignment as projects move from early planning into construction.

PROCESS WITH PRECISION

By thinking about a project both “drywall out” and “drywall in,” the team ensures layout, circulation, and proportion support how spaces will actually be used.

ARCHITECTURAL ALIGNMENT & REVIEW

(Early Planning)

Duet Forma often engages during the earliest stages of a project to evaluate feasibility before design moves too far forward. By reviewing zoning requirements, site constraints, structural considerations, and construction realities early, the team helps determine what is truly possible before major design decisions are made.

This early involvement helps ensure architectural planning, interior vision, and construction strategy move forward with clarity and alignment.

What this includes:

Zoning and site constraint review
Early feasibility studies and planning analysis
Floor plan and spatial flow review
Elevation and proportion review
Identification of potential conflicts before construction

ARCHITECTURAL INTEGRATION

(Design Development)

As the project moves into design development, Duet Forma refines the architectural framework that supports the design vision. The studio coordinates structural systems, architectural openings, and spatial proportions so the building can properly support the interior environment being created.

This work ensures architectural decisions, structural realities, and interior design intent remain aligned as the project develops.

What this includes:

Architectural wall, opening, and structural coordination
Window placement and exterior envelope alignment
Stair, ceiling height, and vertical circulation design
Architectural detailing that supports interior design intent
Coordination between architectural structure and interior design

ARCHITECTURAL COLLABORATION

(Team Coordination)

Duet Forma approaches architecture without a predetermined style or agenda. Every project begins with listening. The goal is to understand how clients want to live, move through, and experience a space before shaping the architecture around it.

Rather than imposing a signature aesthetic, the studio develops architectural solutions that respond to the people using the space, the character of the site, and the realities of construction.

What this includes:

Architectural planning informed by client program and use
Coordination between architecture, design, and construction teams
Development of architectural drawings and detailing
Collaboration with engineers, consultants, and project teams
Guidance through key design and documentation milestones

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!”
