Home Additions Experts
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.
From the first walkthrough to the last punch-list item, Greg or Patryk runs your Home Additions project themselves. That means a scope written out line by line instead of one number, permits pulled and handled with your village, and the same faces on site rather than a crew you've never met.
- Specialized Home Additions expertise
- On-site supervision for every project
- Transparent pricing with no surprises
- Quality craftsmanship guaranteed
"Your Home Additions project deserves the best—we deliver it."

Wilmette permits & building codes for home additions
Wilmette permits go through Community Development at 1200 Wilmette Avenue — paper submittals are preferred (electronic filings take longer to issue) — with a published goal of 10 business days per reviewer for first review. Plans need an Illinois architect's or structural engineer's stamp for structural work or projects over $25,000, reviewers can require one even below that for kitchens, baths, and basement remodels, and every contractor on the permit must hold a Wilmette contractor license before issuance. Exterior work on a designated Wilmette landmark needs a no-fee Certificate of Appropriateness from the Historic Preservation Commission first, and the village also maintains an Appearance Review Commission for design review. GS Construction manages the full permit process — applications, stamped drawings, contractor licensing, and phone-scheduled inspections — on every Wilmette project.
How your Wilmette 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.

We cannot say enough good things about GS Construction and about Greg and Patryk. We hired them on a strong recommendation from a friend and are very pleased with the results. Our project included remodeling a kitchen and master bathroom and adding wood floors to several rooms in our condo. We had definite ideas of what we wanted since we have done many remodeling projects in several previous homes, but both Patryk and Greg added great value with suggestions and ideas of their own based on their experience and talent. Their follow through was excellent and we feel confident that if anything needs attention, they will be there to make it right. P.S. They did a great clean up at the end of the project......i
