Home additions in Lake Barrington, IL
Expanding a home in Lake Barrington often means working with properties built from the 1960s through the 2000s, many of which feature generous lots perfect for thoughtful additions. Whether it's a ranch-style home needing a second story or a two-story Colonial seeking a larger footprint, these projects are about enhancing space while respecting the existing architecture. Many homes here, particularly those built in the 70s and 80s, have floor plans that benefit significantly from added square footage, transforming segmented interiors into open, flowing living areas. We frequently connect new construction to existing structures, ensuring seamless transitions that feel original to the home. This often involves extending kitchens, adding primary suites, or creating dedicated family rooms that integrate naturally with the home's aesthetic.
What Lake Barrington homeowners ask for
Lake Barrington homeowners frequently request two-story additions to expand living areas, often adding new bedrooms, bathrooms, or a dedicated home office above an existing footprint. Another common request is for larger, open-concept kitchen and dining extensions, allowing for more spacious entertaining and family gatherings. We also see interest in sunrooms and screened porches that blend indoor-outdoor living, especially on properties with scenic wooded views.
About Lake Barrington
Lake Barrington's housing reflects its wooded, large-lot character, protected since its 1959 incorporation. This diverse housing stock, from mid-century homes to newer custom builds and townhomes, offers unique remodeling opportunities.
Lake Barrington incorporated in 1959 to keep zoning in local hands, and the wooded, large-lot character it protected shows in every era of its housing. Barrington Harbor Estates off Kelsey Road dates to the late 1950s; Lake Barrington Shores added 1,317 gated townhomes and condominiums around a 96-acre private lake between 1974 and 1996; and newer subdivisions like the custom Enclave of Heritage Estates and Taylor Morrison's Tallgrass carried building through the 2010s into the 2020s. Families here are served by Barrington 220 schools, with Metra's UP-NW line in neighboring Barrington.
The village's founding in 1959 to keep zoning local means additions often work with generous lot sizes and setbacks, particularly in older subdivisions like Barrington Harbor Estates. For the 1970s–1990s Lake Barrington Shores townhomes, additions may involve careful roofline and foundation tie-ins due to their attached nature. Newer custom subdivisions like the Enclave of Heritage Estates and Tallgrass offer opportunities for seamless additions that match existing high-quality construction. The absence of a village-wide water system means any plumbing for additions requires early Lake County Health Department consideration for private wells and septic. When reviewing exterior changes, the village prioritizes maintaining the established wooded, large-lot character, ensuring additions blend harmoniously.
Home additions in Lake Barrington trigger specific reviews related to structural integrity, foundation work, and roof tie-ins, all of which are thoroughly inspected by the village's contracted building code firm. GS Construction & Remodeling manages the entire application and inspection scheduling process, ensuring all phases of your addition meet local requirements.

Our project turned out better than we expected and as things were going along, we added more projects. Patryk, Greg and their team did a fantastic job. They were always so nice to work with, even suggesting things which was helpful. They never left a project until they thought it was perfect. We did a full kitchen remodel, even closing off a window to move a fridge and pantry to the other side to allow more cabinets and much needed counter space. They widen the entrance and the kitchen seems so much bigger. We think it’s Beautiful! They did laminated floors throughout the first floor, painted all walls and new baseboards. They created a wine bar which was just a cubby hole. They put in a pantry like cubby hole in our laundry room and added cabinets and above wall unit. One of the projects we had them add is new wooden stairs to the 2nd floor, white spindles and railing that curves instead of a wall and laminate floors on the 2nd floor. Other odd and ends that they never hesitated to do. We appreciate all they have done in our home, To us, it’s amazing how nice it is and how it should have been all the years we have lived here. Its exciting to show it off, it feels like a new house. These guys are amazing and would definately recommend them to anyone. Very reliable and easy to get in contact with when needed.
