Naples sits on the US-95 corridor in Boundary County, just south of Bonners Ferry, in the Kootenai River valley with the Selkirk Mountains to the west and the Cabinet Mountains to the east. It is quiet country with big views, big weather, and a lot of room to build.
We are based here, so a site visit on your Naples or Bonners Ferry property is a short drive, not a trip. We know the ground, the roads, and what a building needs to stand up to in this valley, and we plan your project around it from the first conversation.

For Naples, Bonners Ferry, and the Kootenai valley
Custom homes & barndominiums
Designed around how you live and the land you own in the valley, in steel or stick-built, and finished throughout.
Shops & recreational
Room for the boat, the bikes, the horses, and the workshop, with living quarters if you want them.
Commercial buildings

Remodels & additions
Additions, outbuildings, and renovations for the home you already own.
Frost, snow, and a site that has to be reached.
A building in the Kootenai River valley has to handle deep frost, heavy winter snow, and properties that may sit well off the highway. That shapes the design: foundations engineered to the soil and frost depth, a roof sized for the snow your ridge actually carries, and access and utilities planned before anything is ordered.

Engineered to your soil and local frost depth, poured and inspected before anything goes up.
Roofs for the snow
Structure and roof designed for the loads your property actually carries.
Access planned early
Driveways, grades, and utilities worked out at the design stage.
