Expert Home Additions Services
GS Construction & Remodeling specializes in professional Home Additions. As a father-son team, we bring decades of combined experience to every project.

- Quality craftsmanship guaranteed
"Your Home Additions project deserves the best—we deliver it."

Des Plaines permits & building codes for home additions
The City of Des Plaines requires building permits for remodeling, additions, repairs, and demolition, issued through the Community and Economic Development Department's Building Division. Contractors must be licensed, bonded, and insured with the City before a permit can be issued. If a basement project adds flood-control measures such as an overhead sewer or backwater valve, the City's Flood Rebate Program can reimburse 30 percent of eligible costs up to $2,000. GS Construction manages the full permit process — application, plan review, and inspection scheduling — as part of every Des Plaines project.
How your Des Plaines project runs
ProcessThe same six stages on every job — free in-home estimate through warranty.
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.
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.
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.
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.
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.
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 and Patryk do amazing work and are incredible to work with! GS Construction completed two extensive bathroom renovations for us, including completely reconfiguring layouts and expanding one. Both bathrooms are absolutely beautiful, and they have significantly improved our family's quality of life in our home. Patryk and Greg are great communicators, take pride in their work, and have good attention to detail. Throughout the project, they really listened to us, took the time to understand what we wanted, kept progress going in a timely manner, and provided expert advice/suggestions and help on specific questions along the way. Every one of their team members did high-quality work. We couldn't be happier with the end result, and definitely will hire them for future renovations!
