Certified Builder Network · Montana
Build your DEN in Montana with the North Brothers.
North Brothers Builders is DEN's certified partner for northwest Montana — building-science-first builders trained on the DEN prefab system, running your build from foundation to final walkthrough.
The Builder
Guided by what endures.
North Brothers is a specialty residential general contractor owned and operated by Mark Manning and Brett Morton, rooted in northwest Montana's tradition of craftsmanship. Their work balances design with long-term performance — homes meant to be durable, comfortable, and built to last for generations.
They're also a Phius certified builder — trained in passive-house building science, the most demanding standard for energy performance and envelope quality in residential construction. It's the same discipline DEN's super-insulated prefab panels are engineered around, which is exactly why they're the network's first partner.

A full-service GC with a portfolio of design-forward Montana homes — we reviewed the work, the licensure, and the building philosophy before anything else.

Building science first
Phius certification means passive-house-level rigor on airtightness, insulation, and envelope detail — the discipline DEN's prefab panel system is built around.
