Home additions in Deerfield, IL

In Deerfield, home additions frequently transform the village's prevalent mid-century ranches, split-levels, and colonials, expanding living areas that often feel constrained by their original footprints. Many homeowners seek to add substantial square footage, extending outward or upward to create more functional and open layouts. This often involves integrating new construction with existing structures, whether it's expanding a kitchen into a sunroom or adding a second story for new bedrooms. The goal is typically to modernize and enlarge homes without sacrificing the established character of Deerfield's residential streets, ensuring seamless transitions in design and materials. We frequently encounter requests to reconfigure cramped first floors and add dedicated spaces for work or recreation, directly addressing the evolving needs of families in these classic Deerfield homes.

What Deerfield homeowners ask for

Deerfield homeowners often request primary suite additions, expanding compact original bedrooms into luxurious retreats with ample closet space and spa-like bathrooms. Family room bump-outs are also highly sought after, providing expansive gathering areas that connect seamlessly with existing living spaces and often open to outdoor entertaining areas. Another common request involves multi-story additions that add new bedrooms and bathrooms, addressing the need for more private space as families grow within their established Deerfield homes.

About Deerfield

Deerfield's housing stock tells the story of the postwar boom, with ranches, split-levels, and colonials filling former farmland. Remodeling that stock is what we do, opening up mid-century floor plans for how families live now.

How your Deerfield project runs

Process

The same six stages on every job — free in-home estimate through warranty.

1

Free in-home estimate

Greg or Patryk — the owners, not a salesperson — walk your space, take real measurements, and give you honest feedback on what your budget buys.

2

Itemized scope & contract

Labor, materials, demolition and disposal priced line by line, not one mystery number. Payment terms and warranty are in the written contract.

3

Design & selections

Bring your own designer, use our architects and designers, or choose everything yourself. Selections are scheduled ahead so lead times never stall the site.

4

Permits & scheduling

We pull and manage building, plumbing and electrical permits with your village — typically 1–2 weeks — and hand you a written schedule before demo day.

5

The build, owner-supervised

Long-standing trade partners working in sequence under daily owner supervision. Your client portal shows the schedule, change orders and current balance.

6

Walkthrough & warranty

We walk the finished job together, close out every punch-list item, hand over manufacturer paperwork, and your written workmanship warranty starts. Our commitment never expires.

Greg came highly recommended for my bathroom remodel. From demolition to final product, I was very happy with my choice in contractors! Greg listened to what I wanted done, made some suggestions and even changed tile layout in the tub area after I changed my mind. He wanted me to be completely happy when he was done. He always left the work area clean each day and start each day on time. Because of the workmanship, GS Construction is doing a family member's bathroom remodel. It was an easy choice!
