Formed in 1993, Harn Construction was founded by the principals of a former Northern Illinois construction firm. In the beginning, Harn Construction concentrated on masonry and concrete contracting; however, over the last 17 years, we have broadened our focus into consulting, contracting, design/build construction management and green building projects.

We concentrate on commercial, institutional, governmental, and residential projects. A great deal of our time and energy is spent establishing and servicing our growing number of repeat clients. We are engaged in construction projects, general maintenance, and remodeling work.
