When my wife, Marge, and I contracted with you to build a house for us, we really didn’t think it was going to be a painless endeavor. As it turned out, it was not only painless, it was fun. We thoroughly enjoyed working with you and your associates during the six month building process. I believe what separates you from other custom home builders is that you are extremely detail oriented and your value added concept is unique to your industry. Both of these qualities saved us a lot of time and money, which we certainly appreciate. It goes without saying that we are very happy and satisfied with our new home.

After looking at many house builders large and small, we contracted with Tri-River Design to build our new home in 2016. We selected the lot location, property transfer, house design, and all options from the Tri-Rivers office and show room in a very efficient manner. We observed the actual house construction on a regular basis by on site inspections. As a construction worker for many years, the over all inspection results were very satisfactory. All house builders use sub-contractors. Tri-River uses the same high quality on a regular basis. Tri-River always had two contractor overseers on site daily. Our house completed on time on budget. Bottom line: We would have Tri-River build for us again. We have recommended Tri-River to friends and family.
