About Us

Billings' Innovative Architects - 2x Best of Houzz
Passion for design is what drives us, the success of our work truly comes from the collaboration that we have with our clients. We pride ourselves in the ability to create great design work that reflects the style and tastes of our clients. Whether it be contemporary, rustic, or traditional; we have the team capable of creating unique and enduring homes. SERVICES PROVIDED Collaborative Design Architects specializes in full architectural design services on a vast array of projects. These archetypes include custom residential projects, remodels/ additions, commercial buildings, civic structures, and master planning/development projects. Arch.406 is the sister company to Collaborative. It is the "design-build" extension of our firm and was set up so that we could manage and build the projects that we were creating. At ARCH.406 we hand select the most talented subcontractors and material suppliers in our area to work on your project. Budget is a key component to the success of a project, but costs should not be the lone driving factor when making decisions on your design. Working through ARCH.406 allows us the opportunity to balance the design, budget and schedule on our residential works.
