Home additions in River Forest, IL

River Forest is an architecture town: Frank Lloyd Wright's first independent commission, the Winslow House, stands on Auvergne Place, Prairie School architect William Drummond lived and built here, and the streets near Thatcher Woods carry a deep stock of Victorian, Prairie, and brick Colonial homes from the village's 19th- and early-20th-century growth. Remodeling here is a balancing act — reworking century-old floor plans for modern kitchens, bathrooms, and finished basements while keeping the woodwork, masonry, and street-facing character that give these houses their value. Plumbing projects add one consideration: the Village runs its own Lake Michigan water system, and its "Get the Lead Out" program reimburses part of the cost of replacing a lead service line — worth folding into a kitchen or bath remodel rather than opening the ground twice. GS Construction plans whole-home renovations, additions, and room-by-room updates around these details, in a village served by District 90 schools, OPRF High School, and Metra's UP-W line to Ogilvie in a little over 20 minutes.

River Forest permits & building codes for home additions

The Village of River Forest requires building permits for remodeling work — structural, electrical, and plumbing changes included — with applications submitted through its online permit portal at riverforest.onlama.com. Homes designated as significant properties get one extra step: exterior work affecting more than 20% of a street-facing facade, or street-visible window replacement, triggers an advisory review by the Historic Preservation Commission (up to 30 days, or 7 for windows) before work begins. The Commission's recommendations are non-binding, but the review window belongs in your project schedule. GS Construction manages the full permit process — portal submission, historic-review coordination, and every required inspection.

5 Stars

GS Construction was the contractor recommended to us for our remodeling project by our designer, Jenn Peterson of J. Peterson Design. The project involved gutting most of the first floor and doing a complete remodel of the kitchen and family room on a 53 year-old home. We could not be more pleased with the work, responsiveness, timeliness and the outcome. Greg and Patryk (Greg's son) are great people. They worked seamlessly with Jenn and had no issue with working to change some of the plans on the fly. They identified some structural issues natural to an older home and resolved them quickly and in very cost-effective ways. We had more contact with Patryk, who walked us through the project step by step from beginning to end. He was always available to talk to us and kept the project on schedule. Any change orders or other modifications were handled quickly and professionally. We recommend GC Construction without any reservations. They do great work and were fun to work with as well. Jim and Dana P The quality of the workmanship was first-rate and our space is exactly what we were hoping for. They were very reasonably priced and
