Home additions in South Barrington, IL
Home additions in South Barrington frequently involve expanding substantial custom-built residences, many dating from the 1980s through the early 2000s, with a growing number of newer homes from the 2010s and beyond. These projects often aim to enhance existing generous floor plans, moving beyond the original footprint to incorporate more elaborate amenities or expand common areas for larger family gatherings and entertaining. We often see requests to integrate new spaces seamlessly into the existing architecture, respecting the custom nature and aesthetic of the neighborhood's housing stock. The large lots typical of South Barrington provide ample space for creative and substantial additions, allowing for significant expansions without compromising outdoor living areas. Whether it's a multi-story wing or an expanded single-level space, the goal is always to elevate the home's functionality and luxury.
What South Barrington homeowners ask for
South Barrington homeowners frequently request primary suite expansions, adding extensive walk-in closets, sitting areas, or even private home offices. Expansions of kitchen and dining areas to create grander, open-concept spaces for large-scale entertaining are also highly sought after. Additionally, we see demand for new sunrooms or four-season rooms that maximize natural light and views of the expansive properties.
About South Barrington
South Barrington is a village of custom homes on generous lots — minimum lot zoning of one and a half acres has shaped it since incorporation in 1959. Remodeling here means working with substantial custom-built houses.
Since incorporation in 1959, South Barrington has counted 44 subdivisions and roughly 43 private lakes and ponds. These include communities like The Glen, The Coves, Sunset Ridge Farms, and South Barrington Lakes, plus the newer Woods of South Barrington and its 55-plus Regency neighborhood. Families are largely in Barrington 220 schools — Barbara B. Rose Elementary is right in town — with Pace I-90 Express service at Barrington Road and Metra's UP-NW line in nearby Barrington.
The 44 subdivisions, including The Glen and Sunset Ridge Farms, each present unique lot sizes and setback requirements that influence the feasible footprint for additions. Working with substantial custom-built houses in communities like The Coves and South Barrington Lakes means tying into diverse roof lines and foundations. For additions, the village's plan review will carefully assess how exterior changes integrate with the existing custom architecture across these varied communities. Given that most homes rely on groundwater and private septic systems, except for The Regency and Woods, additions involving new plumbing must account for these existing infrastructure limitations. Expanding homes in these communities requires careful consideration of the original custom construction and subdivision-specific regulations.
For home additions in South Barrington, the Village's plan review focuses on structural integrity, adherence to zoning setbacks and lot coverage, and the integration of new electrical, plumbing, and HVAC systems. GS Construction & Remodeling manages the full permit application process and coordinates all required inspections throughout the construction phases.

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
