Home additions in Schaumburg, IL
Expanding your home in Schaumburg often means transforming a mid-century footprint to meet contemporary needs. Many of the original Campanelli ranches and split-levels, while charming, offer more compact living areas than modern families desire. A thoughtfully designed addition can seamlessly integrate with the existing structure, providing much-needed square footage without the disruption of relocating. We frequently extend these homes to create larger primary suites, expanded kitchens, or dedicated family rooms that flow naturally from the original layout. Tying into the existing foundation and roofline is a common challenge we expertly navigate, ensuring structural integrity and a cohesive exterior aesthetic. Whether it's adding a second story to a single-level home or extending outwards, our additions are tailored to enhance both functionality and value.
What Schaumburg homeowners ask for
Schaumburg homeowners frequently request first-floor extensions to enlarge kitchens into open-concept great rooms, perfect for entertaining in their mid-century homes. Another common desire is for primary suite additions, creating spacious bedrooms with walk-in closets and luxurious bathrooms where none previously existed. Growing families also seek dedicated home offices or playrooms, often added to the rear or side of their existing footprint.
About Schaumburg
Schaumburg's housing stock, largely built from the mid-20th century onward, presents unique opportunities for renovation. We frequently open up compact kitchens, rebuild hall baths, finish basements, and construct additions to give homes the breathing room growing families seek.
Schaumburg's housing story truly begins in 1959, when builder Alfred Campanelli broke ground on Weathersfield near Schaumburg and Springinsguth Roads. This foundational development grew through more than twenty phases, eventually encompassing roughly a fifth of the village's housing. It started with the "W" section, where ranch models, often carrying New England names like Warwick and Winthrop for their streets, offered a distinct mid-century charm. Beyond Campanelli's influence, we also undertake numerous projects in Timbercrest, where Mor-Well Builders, from the mid-1960s onward, mixed ranches, raised ranches, split-levels, and two-story plans, each presenting unique opportunities for renovation. Similarly, the 1960s single-family blocks of Lexington Fields Estates and the late-1970s and '80s coach homes of Lexington Village offer a diverse array of properties that benefit from our expertise. A unique pocket of Schaumburg plays by different rules: the Olde Schaumburg Centre overlay district, established in 1978 around the Schaumburg and Roselle Road intersection, aims to preserve the character of what began in the 1840s as the farming settlement of Sarah's Grove.
The foundational Campanelli developments like Weathersfield, with its "W" section ranches, and Timbercrest's ranches, raised ranches, split-levels, and two-story plans, often present varied lot sizes and existing roof lines that require careful planning for seamless additions. The distinct mid-century charm of these homes, along with those in Lexington Fields Estates, means additions must respect original architectural styles and foundations. For properties within the Olde Schaumburg Centre overlay district, established around the Schaumburg and Roselle Road intersection, the OSC design review process is a mandatory step before Village Board approval for exterior projects, impacting project schedules. Village-wide, the formal plan review for alterations, including additions, requires detailed drawings and a written scope of work, which we prepare to ensure a smooth permitting process. The limited number of teardowns in Schaumburg, coupled with the desire to maximize existing footprints, makes additions a popular solution for families needing more space without relocating.
Home additions in Schaumburg require multiple inspections throughout the construction process, from foundation and framing to mechanicals and final occupancy, all of which GS Construction & Remodeling expertly schedules and manages. The village's plan review for additions is comprehensive, scrutinizing structural integrity, zoning compliance, and energy efficiency, and we prepare all necessary documentation for a smooth approval.

We had a truly amazing experience with GS Construction remodeling our kitchen and first floor. As remodeling novices, we connected with GS Construction through our designer and were so happy with this match made in heaven. Having heard horror stories from friends about remodels that went on forever and tales of unreliable contractors who don’t communicate, we were nervous when we started and expected the process to be long and painful. Our experience could not have been more different. Greg and Patryk were great at keeping us informed and the total amount of time from demo to the unveiling to friends and family was really reasonable at a little over 2 months. We received great personalized attention and they were great at offering ideas and trouble shooting various things that came up. But the real highlight is the quality of the work. They were so attentive and made sure that we loved every inch of our new space. We have never loved our house more!
