Home additions in Barrington, IL
Home additions in Barrington often involve extending the footprint of classic mid-century ranches and colonials to create more expansive living areas. Many of these homes, while well-built, feature layouts that no longer align with modern family needs for open-concept kitchens or dedicated home offices. A typical home addition project here might involve adding a two-story wing to accommodate a new primary suite on the upper level and an enlarged family room or mudroom on the main floor. For larger, more contemporary homes, additions frequently focus on specialized spaces like sunrooms, dedicated media rooms, or expanded garages. We frequently find ourselves integrating new spaces seamlessly into existing structures, whether it's expanding a kitchen into a bright new dining area or creating a dedicated home gym.
What Barrington homeowners ask for
Barrington homeowners frequently request ground-floor extensions for larger, open-concept kitchens that flow into spacious family rooms, ideal for entertaining. Another common desire is the addition of a luxurious primary suite, complete with a spa-like bathroom and walk-in closet, often on a second story. Growing families often seek mudroom additions with ample storage, especially in homes without existing dedicated entryways. Multi-generational living is also driving requests for in-law suites, either attached to the main structure or as a separate, permitted accessory dwelling unit.
About Barrington
Barrington boasts a rich tapestry of established neighborhoods, from classic colonials and ranches to newer custom homes. GS Construction has been privileged to transform residences across this diverse landscape, understanding the unique character and remodeling challenges of Barrington's varied housing stock.
Barrington, with its charming, walkable historic downtown centered around the iconic Catlow Theater, the bustling Metra UP-NW station, and the vibrant shops along Main Street and Northwest Highway, boasts a rich tapestry of established neighborhoods. The village's housing stock tells a story spanning decades. Many of the homes built in the mid-century, often found in areas like the neighborhoods surrounding Citizens Park, feature sturdy construction. As the village expanded, subdivisions emerged with more contemporary designs. Later developments introduced custom homes with larger footprints. Just beyond the village line, our work seamlessly extends to the grand estate properties of Barrington Hills. We also serve the surrounding Barrington-area communities.
The sturdy construction of mid-century homes in neighborhoods surrounding Citizens Park means foundations and rooflines are often suitable for tying into additions, though smaller, more compartmentalized layouts may require creative design to achieve open concepts. Later subdivisions with more contemporary designs and custom homes with larger footprints often have more generous lot sizes, potentially allowing for greater flexibility in addition size and placement, but still requiring careful consideration of setbacks. The distinct architectural styles and varying lot sizes across Barrington necessitate tailored additions that complement existing structures, whether expanding a family room or adding a new primary suite. For properties within historic districts, exterior changes will require appearance review, ensuring additions respect the village's heritage. Even grand estate properties in Barrington Hills, just beyond the village line, present opportunities for extensive remodeling and integration of sophisticated systems in additions.
For home additions in Barrington, the Village's plan review process meticulously examines structural integrity, zoning compliance, and how new construction ties into existing utility lines. GS Construction manages all necessary permit applications, ensures designs meet setback requirements and lot coverage limits, and schedules every inspection from foundation to final framing and electrical rough-ins.

Testimonials

Real reviews from homeowners. Ask us for live phone references.
Having done a fairly large amount of “research” online I concluded that it was time to get an excellent contractor team and not second rate. GS is A + excellent. From bottom to top, their people care about doing the right thing, they are active listeners who ask for feedback, and have a very positive attitude in achieving excellence in the little matters which leads to big beautiful renovations. The difference between ordinary and extraordinary is that little extra, said a prominent fb coach, and its true in renovations. Greg Szady and Patryk Szady have high quality people and actively work with my selected and excellent designer Jenn Peterson to put my first floor into the 21st century and beyond my expectations. The designer selected very high quality materials and Patryk and Greg delivered excellent renovations installations and detail. Kudos especially to GS flooring experts because everything transformed beautifully. No one has paid me for this review or told me what to say.
