Home additions in Northbrook, IL

Northbrook's housing maps to its postwar boom — the village grew from about 1,265 residents in 1940 to more than 25,000 by 1970 — so much of its stock is mid-century homes on mature lots, now joined by newer infill and rebuilds. The Village pumps its own Lake Michigan water, and only a few hundred lead service lines remain, mostly at homes built before the mid-1950s; on plumbing-heavy kitchen and bath remodels in older houses that's worth checking early, since Northbrook runs a cost-share program that reimburses up to half the private-side replacement cost. Expansion is common enough here that projects growing a home's floor area by more than 115% get their own "Major Renovation" permit category. 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.
