Home additions in Northbrook, IL
Expanding a home in Northbrook often means thoughtfully integrating new space into existing mid-century ranches, split-levels, and two-story homes. Many of these properties, built between the 1950s and 1970s, feature defined rooms that homeowners now seek to open up or extend for modern living. A typical home addition here might involve pushing out a rear wall to enlarge a kitchen and family room, or adding a second story to a single-level ranch to accommodate growing families. The architectural styles of these eras require careful planning to ensure the addition blends seamlessly with the original structure, maintaining the home's character while significantly improving its functionality. We often address the need for more spacious living areas, dedicated home offices, or enhanced private suites within these established layouts.
What Northbrook homeowners ask for
Northbrook homeowners frequently request two-story additions to expand existing single-story footprints, particularly for adding primary bedrooms with en-suite baths. We also see strong demand for rear additions that extend kitchens and family rooms into larger, open-concept spaces suitable for entertaining. Another common request involves creating mudrooms or dedicated utility spaces, often adjacent to garages, which many mid-century homes lack.
About Northbrook
Northbrook's housing maps to its postwar boom, so much of its stock is mid-century homes on mature lots, now joined by newer infill and rebuilds. This means a variety of remodeling opportunities for homeowners.
The village grew from about 1,265 residents in 1940 to more than 25,000 by 1970. GS Construction brings kitchens, bathrooms, basement build-outs, additions, and whole-home renovations to Northbrook households, from houses near the downtown Shermer Road Metra station to the streets around Glenbrook North and Techny Prairie Park.
The rapid growth from 1940 to 1970 means many homes are mid-century, often with lot sizes and setbacks that require careful planning for additions to meet current zoning. Additions to homes built before the mid-1950s should account for potential lead service lines when tying into plumbing, though the Village offers a cost-share program. The prevalence of projects growing a home's floor area by more than 115% necessitates understanding the specific "Major Renovation" permit category. Integrating additions near downtown Shermer Road or Glenbrook North requires attention to existing rooflines and foundations to ensure seamless tie-ins. The Village's review process for exterior changes will likely scrutinize how new construction blends with the established styles of these diverse subdivisions.
Home additions in Northbrook require detailed plans for structural elements, foundations, and roof tie-ins to be reviewed by the Village. GS Construction handles all necessary applications and coordinates the mandatory inspections throughout the construction process, from footing and foundation to framing, electrical, plumbing, and final occupancy.

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!
