Long distance building projects are never without challenges, but we were so happily surprised by the whole experience with Haas Builders.

At the time of our build, we were unable to visit the area on a regular basis.  In fact, we walked the site with John once prior to breaking ground, once during framing and once more near completion.  John was very good at keeping us up to date on the progress and offered good advice on materials and design throughout our regular off-site communications. It was such a pleasure to work with Haas Builders!  Their team exemplify hard work, honesty, integrity and skill. The artistry and craftsmanship is clearly apparent throughout our property.

One of the things that was especially outstanding about our experience with Haas Builders was the fact that our home came in on budget.  We have been involved in other building projects and had started to believe that this was impossible.  Nope, not with Haas Builders – no cost overruns!  Wow. We still can hardly believe it.

Finally, the fact that John lives in the area and is an active and integral part of the community is also a big plus.  John personally cares about the Spanish Peaks and Big Sky community, and the people who live there; whether full time or part time.  Our experience with John as a builder is also unique in that we are better friends as the years go by.  We appreciate his responsiveness to post-build questions and continued willingness to assist us with upgrades to our home.  Our home is five years old and we continue to love it more and more!

Haas Builders played a major part in the building of my house. From early designs to unloading trucks to daily work. They supported Builder Michael Reynolds in the construction of the Earthship.  And I do believe we all had fun as well.

Haas Builders helped me build my first commercial building in Big Sky Montana. John Haas has great vision in his personal building projects as well as those he does for others. Because of this, communication  through every step of the process is always very clear. This company is able to integrate the vision of the owner, the architect, and tie it all together with the contractors and subcontractors in a way that creates a beautiful product that stays within budget and is well-built. I highly recommend Haas Builders.

Romney Residence 1

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

Originally John had designed the house as as “spec house”, but when we decided to build the house as our permanent home, John was actively involved in modifying the design to suit our family’s needs.  In addition to including several “great to have” details that we wouldn’t have thought about in designing our home, John included several items that allowed us to easily adapt our home for future needs (such as roughing in plumbing in the unfinished space above the garage to allow for an easy and inexpensive recent conversation to a fully finished living space).

I would highly recommend John and Haas Builders as a high quality, hands on builder.

We used Haas Builders for the interior finishing of our commercial condo purchased in 2018 and were very pleased with our finished product. It was a great team to work with and we have received many compliments on the looks of our commercial space.

We would like to thank you again for the beautiful home that you built for us in Big Sky MT. You were simply great to work with during the initial design process, the selection of materials and finishes and the entire building process. Haas Builders was extremely professional in its approach to any challenges which arose during construction. The responsiveness by both you and Cassandra in dealing with post-construction issues has also been much appreciated.

Yvonne and I are delighted with how our new house turned out. It is the mountain retreat that we have always wanted where we can spend time with friends and family. We love spending as much time there in Big Sky as possible.

Our little remodel went awesomely. It was on time and under budget. On time was important because we rented another house for 6 weeks and our remodel was finished when we returned.
