Home additions in Winnetka, IL
Expanding a home in Winnetka often means harmonizing new construction with the existing character of 1920s Tudors, classic Colonials, or mid-century moderns. Many additions involve extending a kitchen into a larger great room, integrating a new primary suite, or creating dedicated office and recreation spaces. The challenge lies in seamlessly blending the architectural style, matching the exterior materials, and tying new rooflines into older structures without compromise. Older foundations, often stone or block, require careful assessment for new load-bearing walls and integrated slab or basement extensions. From two-story rear extensions to side bumps-outs for expanded living areas, each project respects the original footprint and village aesthetics.
What Winnetka homeowners ask for
Winnetka homeowners frequently seek additions that expand living and dining areas, creating open-concept spaces from more compartmentalized older layouts. Adding a ground-floor primary suite with accessible design features is another common request, particularly in homes where all bedrooms are currently upstairs. Dedicated home offices or multi-generational living spaces, often on the first floor, are also popular additions, reflecting changing lifestyle needs.
About Winnetka
Winnetka's housing runs from 1890s-1920s Tudors and colonials on the tree-lined blocks east of Green Bay Road to the storefront charm of Hubbard Woods, in a village that takes architecture seriously.
Crow Island School here is a National Historic Landmark. District 36 schools feed New Trier's Winnetka campus, and three Metra UP-N stops — Hubbard Woods, Winnetka, and Indian Hill — serve the village.
The village's pre-war floor plans often mean working within smaller, compartmented layouts, requiring creative solutions for open-concept additions. When considering additions, the original foundations, whether stone or block, need careful assessment for new load-bearing walls and integrated slab or basement extensions. The presence of plaster and lath construction in vintage homes means planning for the careful integration of new wall systems and finishes. Coordinating additions with Winnetka's landmark and demolition review, when applicable, is crucial for exterior changes. Integrating new rooflines into older structures requires careful consideration to maintain the existing architectural character, especially given the history of varied housing styles.
Home additions in Winnetka trigger comprehensive plan review, including structural engineering, new foundation work, roof tie-ins, and all associated electrical, plumbing, and mechanical installations. GS Construction & Remodeling coordinates all required inspections with the Village of Winnetka, ensuring every phase of the addition meets local building codes and progresses efficiently.

We have used GS for two bathroom projects-the first a small update; the second a complete remodel. We were thrilled with both. Everything was as promised; the timeline, price, and what it would look like. We were able to buy our own tile and fixtures and were not tied to any company's showroom. We got what we wanted and likely saved money doing so. GS also installed interior doors. The workmanship was great. The only downside is that now the bathrooms are the two nicest rooms in the house! I would heartily recommend GS construction!
