What Our Customers Say

I almost never use my air conditioner in the summer. While my neighbor's A/C is running my house stays cool and comfortable for days even in the hottest weather. I loved working with Gene Becker. He helped with everything involved in building. He gave good advice and truly has the customer's best interest at heart when making suggestions. If I had to do it all over again, he would be the first person I would call. - Carolyn, Appleton.


It is comforting to know that with bad weather approaching and my kids home alone, that we live in a ICF house. Kinda makes it worth the investment right there. - Jake, Weyauwega

I couldn't believe that just by adjusting my design I could significantly lower my costs and increase energy efficiency. Allan, Princeton.


I can shut off the heat in my cabin up north in the winter and not drain the pipes and yet nothing freezes. Steve, Mountain


Our home building project with Gene convinced my father, who was a builder for 50 years that there IS a better way to build.  Connie and Don, Hortonville.

An absolutely wonderful company to work with. Gene, Gina and all the sub-contractors were very helpful and considerate during our entire building process. We have a beautiful, energy efficient home and could not have asked for more. Gene worked with us every step of the way during construction. Prior to beginning the build, he made sure we understood ICF construction, our budget, and the approximate time line. We were able to see where every dollar went. Every sub-contractor was easy to work with and listened to us. All questions and concerns were dealt with immediately. The end result is we have a beautiful, quality, well built, energy efficient home. Martha and Tom, Fond du Lac​

Thank you Great Building Concepts, Envision Builders, and all of the subcontractors for creating our forever home! A place where we get to watch our children grow! Our home is energy efficient with being ICF, we have absolutely no regrets with this choice. Every day we wake up and can’t believe what we accomplished, thank you for helping us build our beautiful home. Tiffany, Ripon

Gene and his team built our extremely energy efficient home 8 years ago. I recently called to have my 500 gallon LP tank filled, and the gentleman couldn’t understand that we only had our tank filled once a year. He said, “No way, you must burn w/wood or use a pellet stove”. I said “No.” I told him if he didn’t believe me, he could come out and see our house. :) After 8 years of living here, we have been so grateful to have hired Gene to help us with difficult decisions during the building process. He offered helpful, professional assistance that made the whole process come together easily. Yes, I’m bragging about him...because that is how satisfied we are with his work. Gene went above and beyond with what we expected!! He met our budget and ensured deadlines were met! He and his team were Excellent!! ​Susan, Shiocton
