Iron + Branch Expands Into Vail, Breckenridge, and Aspen

Castle Rock Design-Build Studio Extends Mountain Home Services to Vail, Breckenridge, and Aspen

Castle Rock, United States – May 2, 2026 / Iron + Branch Design/Build /

Iron + Branch Design/Build, the Castle Rock-based design-build studio founded by Travis Dunkum, has announced the expansion of its integrated architecture and construction services into Colorado’s high-country resort markets, bringing more than three decades of residential construction experience to clients in Vail, Breckenridge, and Aspen.

The move extends the studio’s established presence in Douglas County, where ironandbranchdesignbuild.com has built a reputation for unifying architecture, interior design, and construction under a single roof – an approach that reduces the fragmentation common in residential building projects.

A Castle Rock Foundation Built Over 30 Years

Travis Dunkum’s path to design-build was not the result of a pivot or rebrand. He spent more than 30 years working across the full range of residential construction before launching ironandbranchdesignbuild.com in Castle Rock. That experience shaped a process where design decisions and construction realities are considered together from the first client conversation – not reconciled later when changes carry a higher cost.

For Douglas County homeowners, that depth of local knowledge carries practical weight. The terrain across the Front Range foothills introduces grading challenges, soil conditions, and setback requirements that differ from the Denver metro flatlands. ironandbranchdesignbuild.com operates with working knowledge of Douglas County building codes and the site-specific demands that define construction in the area – factors that influence structural choices, material sourcing, and project timelines.

As a castle rock custom home builder, the studio has developed a design language that reflects the region’s mountain-modern sensibility: clean structural lines, natural materials, and an orientation toward Colorado’s landscape rather than away from it.

High-Country Reach as a Natural Extension, Not a Generic Expansion

The expansion into Vail, Breckenridge, and Aspen is framed by Dunkum not as an effort to serve all of Colorado, but as a logical step for clients whose lifestyle spans the Front Range and the mountains.

“We have clients who live in Castle Rock and want a second home in Breckenridge, and they do not want to manage two separate builder relationships,” said Travis Dunkum, Founder of ironandbranchdesignbuild.com. “Our studio has completed over 30 years of residential projects across varying elevations and conditions. Taking that integrated process into the high country is a continuation of the same work — not a different business.”

Luxury mountain homes Colorado buyers pursue in resort communities involve their own set of construction variables – compressed build seasons, altitude-specific material performance, and permitting requirements that vary by county and municipality. By extending the same architecture-design-construction model that anchors its Castle Rock operation, ironandbranchdesignbuild.com is positioned to manage those variables without the handoffs that typically slow mountain projects.

The Design-Build Model as a Structural Advantage

The integrated model at ironandbranchdesignbuild.com means the architect, the designer, and the builder are not separate firms negotiating over scope and budget. They operate as a single team under a shared process with one point of accountability. For clients pursuing luxury mountain homes Colorado demands genuine construction coordination, that distinction has a direct effect on cost transparency and schedule reliability.

Dunkum has structured the studio so that clients receive a documented process rather than verbal assurances. Selections, specifications, and construction milestones are tracked within a shared system, reducing the ambiguity that tends to compound across longer custom home timelines.

Serving Front Range Relocators and Douglas County Homeowners

Castle Rock has drawn consistent relocation interest from Denver metro buyers seeking lower density and proximity to open space without losing access to the city. That demographic – families relocating from urban cores, professionals seeking property with acreage, buyers building at this scale for the first time – represents a significant portion of the studio’s client base.

ironandbranchdesignbuild.com approaches those clients with a pre-design process that addresses site selection, local zoning constraints, and long-term livability before a floor plan is drafted. For relocators unfamiliar with Front Range building dynamics, that early-stage guidance functions as a practical service rather than a preliminary formality.

The studio’s presence in both Castle Rock and Colorado’s mountain resort corridors reflects a client profile that increasingly moves between both environments – and a builder that has structured its services to follow that pattern with consistency.
