Our Award Winning Work

Holtz Builders is proud to have built a multitude of projects that have received regional and national recognition from ABC’s Project of Distinction.

ABC Projects of Distinction are about recognizing the most impressive construction projects in Wisconsin. Entrants do not compete against other contractors, but instead on a point-level basis. The distinct projects were evaluated by 22 judges who put their architectural, engineering, and construction knowledge to work with a tough set of criteria this past fall.
