Arnzen Building Construction has become a key player in the changing face of north central Idaho. We have grown into a competitive general contracting firm in the region, building and remodeling many residential, commercial, educational, medical and public works projects.

Our extensive experience involves all aspects of building. In residential construction, we generally handle all building phases with in-house crews. These phases include excavation, site work, foundation, flat cement, framing, roofing, siding, interior finish and trim. In the commercial field, we have completed a wide variety of buildings and remodels.

We maintain our high quality construction and workmanship with a stable, long time work force. Field experience ranges from 11 to 30 years. Our office staff is willing and capable of answering any questions and assist with communication between project team members during the building process. Besides wide-ranging building knowledge, experience and friendly customer service, we are also fully insured for your protection.

As a local company, we are familiar with most local subcontractors and their capabilities. We also have many contacts and sources outside the area. We coordinate well and gladly give opportunities to owner specified local subcontractors to bid and perform work.


Our reputation is to do the job precisely according to specifications. We pride ourselves on complete customer satisfaction. Project excellence, personal attention and quality service are the fundamentals of the Arnzen philosophy.
