Home additions in Riverwoods, IL
Expanding a home in Riverwoods typically means adding functional space while respecting the original architecture and abundant natural surroundings. Many mid-century ranches and split-levels, while charming, often lack the open-concept living and dedicated spaces modern families desire. Our home additions here frequently involve extending living areas, creating new primary suites, or building two-story additions that thoughtfully integrate with existing rooflines and exterior finishes. The goal is to provide seamless transitions from old to new, preserving the character of these unique homes while enhancing their livability. We meticulously plan additions to complement the established aesthetic, whether that's a Humrich-inspired contemporary extension or a sympathetic expansion of a traditional ranch.
What Riverwoods homeowners ask for
Homeowners in Riverwoods frequently request spacious family room additions, often extending off the rear of mid-century homes to create brighter, more open gathering areas. New primary suites, sometimes designed as two-story additions, are also popular, providing larger bedrooms, walk-in closets, and spa-like bathrooms where space was previously limited. Another common request involves expanding existing kitchens or dining areas to accommodate larger social gatherings and integrate with outdoor living spaces, a natural fit for Riverwoods' large lots.
About Riverwoods
Riverwoods incorporated in 1959 specifically to protect its woodlands, and that origin still shapes every remodel here. Homes sit on large wooded lots governed by the village's Tree and Woodland Protection Ordinance, so additions, decks, and exterior work get planned around protected trees from day one.
The housing stock leans mid-century — including more than 40 nature-infused modernist houses designed by architect Edward Humrich in the 1950s and '60s — alongside later ranches and custom builds along Riverwoods Road and Portwine Road. Families are served mostly by Deerfield District 109 schools and Deerfield High School, with portions attending Stevenson, and Metra's Milwaukee District North nearby in Deerfield.
The prevalence of mid-century homes, including Humrich's modernist designs, means additions must consider existing rooflines and foundations for seamless integration. Later ranches and custom builds along Riverwoods and Portwine Roads will have varying lot sizes and setbacks, requiring careful site analysis. The Village Engineer's review for additions will scrutinize how new rooflines tie into existing structures and the integrity of foundations. For homes on private wells, plumbing for new kitchens or baths in an addition will necessitate confirming the required annual well test. Our approach to additions respects the Humrich-era architecture, ensuring new construction is sympathetic to the original design.
For home additions in Riverwoods, the Village Engineer's plan review will focus on structural integrity, foundations, and how new rooflines tie into existing structures. GS Construction manages all required inspections, from footing and foundation to framing, electrical, plumbing, and final occupancy, coordinating with the Village Building Department throughout the project.

Greg came highly recommended for my bathroom remodel. From demolition to final product, I was very happy with my choice in contractors! Greg listened to what I wanted done, made some suggestions and even changed tile layout in the tub area after I changed my mind. He wanted me to be completely happy when he was done. He always left the work area clean each day and start each day on time. Because of the workmanship, GS Construction is doing a family member's bathroom remodel. It was an easy choice!
