Home additions in Wilmette, IL
Home additions in Wilmette often involve expanding the footprint of classic pre-war homes in areas like CAGE, where smaller original layouts benefit immensely from added space. For these Victorians, Tudors, and Colonials, a typical addition transforms a cramped kitchen into an open-concept living area or provides much-needed extra bedrooms on an upper floor. Homes built mid-century, common further west, frequently see additions designed to create larger family rooms, home offices, or primary suites that were less common in their original designs. Many Wilmette homeowners seek to retain the charm and architectural integrity of their existing property while seamlessly integrating new, functional spaces. This balance requires meticulous planning to match rooflines, exterior materials, and interior transitions.
What Wilmette homeowners ask for
Wilmette homeowners frequently request two-story additions to expand upward, often adding new bedrooms, bathrooms, or a dedicated primary suite above an existing footprint. Ground-level expansions are also common, particularly to enlarge kitchens, create mudrooms, or add sunrooms that blend indoor and outdoor living. For many, the goal is to enhance livability and accommodate growing families without sacrificing the home's historic character.
About Wilmette
Wilmette offers a diverse architectural tapestry that speaks to its long history as a desirable North Shore community, and GS Construction is intimately familiar with the nuances of remodeling homes across its distinct eras.
East Wilmette, particularly the charming CAGE neighborhood—named for Chestnut, Ashland, Greenwood, and Elmwood avenues—is a treasure trove of pre-war architecture. Here, you’ll find an abundance of colonials, Tudors, Victorians, and foursquares, many constructed between the 1890s and 1930s. Their proximity to landmarks like Gillson Park and the distinctive 1928 Spanish Court arcades of Plaza del Lago adds to their enduring appeal. As you move farther west in Wilmette, the housing stock transitions towards mid-century designs, particularly around areas like Edens Plaza. These homes, often built from the 1950s onward, present a different set of remodeling opportunities and challenges. The community's excellent public schools, with most of the village feeding into District 39 and then the highly regarded New Trier High School, also contribute to the desirability of remodeling and improving homes here. Commuting is well-served by both the Metra UP-N line from the Wilmette Metra station and the Purple Line's Linden terminal, making home improvements a sound investment for families valuing both quality of life and convenient access to Chicago.
The pre-war architecture in East Wilmette’s CAGE neighborhood, with homes from the 1890s-1930s, often means working with smaller lots and established setbacks, requiring careful consideration for footprint expansions. Moving west, mid-century homes from the 1950s onward around Edens Plaza might offer slightly more open floor plans but still present opportunities for additions that respect original rooflines and foundations. The sturdy original construction of these homes, whether Victorians, Tudors, or Colonials, implies tying into robust but sometimes aged foundations and structural elements. Lot constraints throughout Wilmette influence the scope of additions, necessitating thoughtful design to maximize space without overwhelming the property. Significant exterior changes, particularly additions in established areas, may be subject to appearance review by the Village, ensuring design harmony with the neighborhood aesthetic.
For home additions, Wilmette's plan review will heavily scrutinize structural integrity, foundation details, and the seamless integration of new and existing rooflines. GS Construction & Remodeling expertly manages all necessary applications, stamped drawings, and coordinates the sequential inspections required for new construction elements.

We cannot say enough good things about GS Construction and about Greg and Patryk. We hired them on a strong recommendation from a friend and are very pleased with the results. Our project included remodeling a kitchen and master bathroom and adding wood floors to several rooms in our condo. We had definite ideas of what we wanted since we have done many remodeling projects in several previous homes, but both Patryk and Greg added great value with suggestions and ideas of their own based on their experience and talent. Their follow through was excellent and we feel confident that if anything needs attention, they will be there to make it right. P.S. They did a great clean up at the end of the project......i
