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.

How your South Barrington project runs

Process

The same six stages on every job — free in-home estimate through warranty.

1

Free in-home estimate

Greg or Patryk — the owners, not a salesperson — walk your space, take real measurements, and give you honest feedback on what your budget buys.

2

Itemized scope & contract

Labor, materials, demolition and disposal priced line by line, not one mystery number. Payment terms and warranty are in the written contract.

3

Design & selections

Bring your own designer, use our architects and designers, or choose everything yourself. Selections are scheduled ahead so lead times never stall the site.

4

Permits & scheduling

We pull and manage building, plumbing and electrical permits with your village — typically 1–2 weeks — and hand you a written schedule before demo day.

5

The build, owner-supervised

Long-standing trade partners working in sequence under daily owner supervision. Your client portal shows the schedule, change orders and current balance.

6

Walkthrough & warranty

We walk the finished job together, close out every punch-list item, hand over manufacturer paperwork, and your written workmanship warranty starts. Our commitment never expires.

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
