Basement finishing in Winnetka, IL

Winnetka's housing runs from 1890s-1920s Tudors and colonials on the tree-lined blocks east of Green Bay Road to the storefront charm of Hubbard Woods, in a village that takes architecture seriously — Crow Island School here is a National Historic Landmark. Most remodels start inside vintage construction: plaster and lath, generations of patched wiring, and water services the Village's own utility reports are still lead or partially lead at roughly a third of its 4,494 connections. GS Construction builds those realities into the plan — kitchens opened up within pre-war floor plans, primary baths reworked from compartmented layouts, basements dried in and finished under original foundations, additions coordinated with Winnetka's landmark and demolition review when it applies, and whole-home renovations that fold service upgrades in while walls are open. District 36 schools feed New Trier's Winnetka campus, and three Metra UP-N stops — Hubbard Woods, Winnetka, and Indian Hill — serve the village.

Winnetka permits & building codes for basement remodels

Winnetka has no online permit portal — applications are Village PDF forms filed with Community Development at 510 Green Bay Road, and interior remodels typically clear plan review in two to three weeks (additions closer to three). Since January 1, 2024, major permit fees run 3% of estimated construction value, and a permit is triggered by structural work, any electrical, plumbing, or mechanical changes, or removing 100 square feet or more of drywall or plaster. The Landmark Preservation Commission reviews alterations to designated landmarks and weighs in on demolition applications. GS Construction manages the full permit process — scope-of-work packets, trade worksheets, and phone-scheduled inspections — on every Winnetka project.

5 Stars

Patryk (and team) were the best to work with. They helped us with a remodel on our basement (including the addition of a dry bar about 4 months later) and we couldn't be happier with the finished product. They were transparent with us through the entire project (through crazy supply chain issues). When they couldn't get something they were up front with us providing options that might be easier to secure to finish the project in a more timely manner. His entire team is honesty so delightful to work with and have in my home. I've had contractors in my house where it's somewhat uncomfortable and Patryk's team is all amazing. The communication about when they would be coming by was seamless. And as a woman (who was basically running this project) they weren't condescending or rude to me either. I cannot wait to work with them again and would hire them in a heartbeat.
