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.

How your Schaumburg 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.

Testimonials

Your Neighbours in Schaumburg Love Us

Real reviews from homeowners. Ask us for live phone references.

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!
