1938 median housing stock
Winnetka doesn't follow that pattern. The local median build year here runs to 1938, which puts a large share of the housing stock ahead of the postwar building boom entirely. That's not a small gap. A home built in the late 1930s went up with a garage structure sized and framed for the cars and hardware of that decade, long before the torsion-spring, steel-panel doors that became standard from the 1950s onward.
