Located in the heart of Campbell County, Gillette offers a blend of community, open landscape and lasting quality. Known as a center for energy and industry, the area also supports a growing market for custom homes and modern ranch estates.

Rob Mills Architecture & Interiors designs refined residences ideal for this part of Wyoming for clients seeking space, resilience and architectural integrity.

Homes in Gillette are often defined by their use of regional materials such as stone, timber and brick, all with considered craftsmanship and classic proportions. Our clients value homes that feel lasting and livable, with spaces designed for family, gathering and retreat. Whether building new or restoring an existing home, RMA brings a calm, clear and collaborative process to each project.

The climate in this region calls for homes that perform year-round. We address orientation, insulation, and material selection early in the process to ensure that each home remains comfortable through Wyoming’s cold winters and warm summers. Design decisions are led by longevity, livability and light.

Our studio works across a diverse range of styles, tailoring each project to suit both client and context. As a holistic practice, we offer architecture, interior desig,n and styling in one complete service. Every detail is thoughtfully resolved to reflect how you want to live.
