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.

How your Winnetka 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.

We have used GS for two bathroom projects-the first a small update; the second a complete remodel. We were thrilled with both. Everything was as promised; the timeline, price, and what it would look like. We were able to buy our own tile and fixtures and were not tied to any company's showroom. We got what we wanted and likely saved money doing so. GS also installed interior doors. The workmanship was great. The only downside is that now the bathrooms are the two nicest rooms in the house! I would heartily recommend GS construction!
