Haas Builders: Big Sky, Montana – A documentation of a build “Fishcamp”

We worked with John Haas and Haas Builders to build our home in Spanish Peaks over 10 years ago.  Our family of 5 has resided in the house full-time for over ten years and recently I was reflecting on how well built the house is and how well it has withstood the test of time.  We have not had a single issue (other than routine maintenance):  no roof leaks, structural/settling issues, or interior systems failures in over 10 years of full time occupancy.  In addition, the design and functionality of the house has withstood the past 10 years; there is nothing we would change.  This is a credit to the hands on approach of John and his team as well as his longstanding working relationship with some of the highest quality subcontractors in Montana.
