Home additions in Prospect Heights, IL
Expanding a home in Prospect Heights often involves thoughtfully extending the footprint of 1950s and 60s ranches and split-levels, which frequently present opportunities to enhance existing living areas. Many of these homes, while structurally sound, feature original layouts that can feel restrictive by modern standards, making additions a popular choice for families seeking more versatile spaces. A typical home addition project here transforms a smaller, compartmentalized interior into a more open and functional environment, often integrating new square footage seamlessly with the existing brick or siding. We commonly see homeowners seeking to add dedicated primary suites, expand kitchens into larger great rooms, or create multi-purpose family rooms that flow into the generous outdoor spaces. These projects address the desire for increased living space and improved functionality while honoring the home's original character and the spacious half-acre lots common throughout the area.
What Prospect Heights homeowners ask for
Prospect Heights homeowners frequently request two-story additions to expand primary bedrooms with en-suite bathrooms and walk-in closets, effectively doubling the usable space without significantly increasing the ground-level footprint. Another common request is for single-story family room or sunroom additions, often off the rear of the home, designed to maximize natural light and provide a seamless transition to the expansive backyards. These additions often include mudrooms or laundry areas to enhance daily functionality.
About Prospect Heights
Prospect Heights has been Chicagoland's take on country living since 1935. This blend of spacious lots and more compact modern living defines the remodeling landscape here.
Prospect Heights was founded when developers Carlton Smith and Allen Dawson built the first homes near Camp McDonald and Elmhurst Roads. The city, incorporated in 1976, grew out of that vision: postwar ranches on half-acre lots, with later condo and townhome pockets such as the Rob Roy development off Wheeling Road. The original housing stock, predominantly built in the 1950s and 60s, consists of well-built, often brick, ranch and split-level homes. The city's growth has seen distinct areas develop, from the original ranch homes near Camp McDonald Road to the townhomes and condos around Rob Roy Golf Course, offering a diverse range of renovation opportunities. GS Construction remodels these homes end to end — kitchens, baths, basement finishing, additions that half-acre lots absorb easily, and whole-home renovations — all within minutes of District 23's neighborhood schools like MacArthur Middle School, the Prospect Heights Metra station, and Chicago Executive Airport, which the city co-owns with Wheeling. Whether it’s modernizing a classic ranch near Lions Park or updating a condo convenient to the Gary Morava Recreation Center, we approach each project with precise local knowledge.
The postwar ranches on half-acre lots near Camp McDonald and Elmhurst Roads offer generous space for additions, easily absorbed by the large lot sizes without setback issues. Tying into the original 1950s and 60s brick ranches and split-levels requires careful consideration of existing roof lines and foundations to ensure seamless integration. For homes with private wells, plumbing for additions, especially kitchens and baths, must be planned from day one to accommodate the water source, filtration, and pressure. While Prospect Heights lacks historic districts or complex appearance review boards, the village still reviews exterior changes, focusing on how additions respect the existing character and spaciousness of properties. Our deep familiarity with the structural aspects of 1950s and 60s construction, including electrical and plumbing configurations, ensures additions are tailored to the unique characteristics of these homes.
For home additions in Prospect Heights, the building department meticulously reviews structural plans, foundation work, roof tie-ins, and all new electrical, plumbing, and HVAC systems. GS Construction & Remodeling expertly navigates this process, managing all permit applications, plan submissions, and scheduling every required inspection from foundation to final occupancy.

Greg and Patryk do amazing work and are incredible to work with! GS Construction completed two extensive bathroom renovations for us, including completely reconfiguring layouts and expanding one. Both bathrooms are absolutely beautiful, and they have significantly improved our family's quality of life in our home. Patryk and Greg are great communicators, take pride in their work, and have good attention to detail. Throughout the project, they really listened to us, took the time to understand what we wanted, kept progress going in a timely manner, and provided expert advice/suggestions and help on specific questions along the way. Every one of their team members did high-quality work. We couldn't be happier with the end result, and definitely will hire them for future renovations!
