Home additions in Barrington Hills, IL
Home additions in Barrington Hills typically involve expanding gracious custom-built residences, often dating from the 1970s through the early 2000s. These homes, characterized by their generous footprints and classic architectural styles like Colonial, Traditional, or French Country, frequently present opportunities to enhance existing living spaces rather than dramatically alter their overall aesthetic. We often find ourselves integrating new wings or expanded rooms that seamlessly blend with established rooflines and exterior finishes, preserving the original character of these estate properties. Adding square footage means careful consideration of foundation tie-ins and structural load transfers, especially for two-story additions, ensuring the new structure is robust and integrated with the existing home's engineering. The objective is always to create a harmonious expansion that feels original to the house, whether it's an expanded primary suite or a larger family gathering space.
What Barrington Hills homeowners ask for
Barrington Hills homeowners frequently request multi-room primary suite additions, incorporating spacious bedrooms, spa-like bathrooms, and walk-in closets that reflect modern luxury while complementing the home's established elegance. Expansions of existing kitchens into grander culinary and entertaining spaces, often including butler's pantries or larger dining areas, are also highly sought after. Another common request is for dedicated home offices or studies, often with custom millwork, to accommodate professional needs within these expansive properties.
About Barrington Hills
Barrington Hills is a unique village of estate properties on five-acre minimum zoning, with a deep equestrian tradition. Remodeling here has its own rules, as nearly every home runs on a private well and septic system.
Barrington Hills is unlike anywhere else we work: a village of estate properties on five-acre minimum zoning, spread across four counties (Cook, Kane, Lake, and McHenry), with a deep equestrian tradition of barns, paddocks, and riding trails. Families here are served by Barrington 220 schools with Metra service from nearby Barrington village.
The earliest subdivisions, developed from the 1920s through the 1950s, feature larger lots that often provide ample space for substantial additions, though well and septic system locations are critical for new plumbing. Homes from the 1950s to the 1970s, often with mid-century modern or ranch styles, require careful roofline integration to maintain architectural consistency. The 1970s through the 2000s saw numerous custom builds, and additions to these homes typically involve matching existing foundations and roof pitches for a seamless blend. Village reviews for exterior changes emphasize preserving the character of these custom-built houses, ensuring new construction respects established aesthetics. For any addition, the long private drives and large parcels influence site logistics, requiring detailed planning for material staging and landscape protection.
Home additions in Barrington Hills require a comprehensive plan review to ensure compliance with zoning setbacks, lot coverage limits, and structural integrity. GS Construction & Remodeling manages the full permitting process, including foundation, framing, roofing, and mechanical inspections, ensuring all new construction elements meet Village standards.

Testimonials
Your Neighbours in Barrington Hills Love Us
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.
