ARCH 406
Billings, Montana
Custom builds Tiny homes
ARCH 406 is a full-service design-build contractor in Billings, Montana, founded by architects Brian Johnson, Nick Pancheau, and Jeff Kanning — partners in Collaborative Design Architects — to serve clients whose custom projects were too small for most general contractors. The firm brings licensed architectural oversight to every tiny home build, from initial design through final walkthrough.
Their flagship model, the Nomad, starts at $68,000 (or $72,500 fully furnished) and is built to handle Montana winters: walls exceed R-20, floors reach R-19, and the roof system approaches R-30. Additional models include the Wedge and the Mansard. As of May 2026, ARCH 406 operates in the Montana market.
