Homes Older Than Home Air Conditioning Itself
Birmingham's downtown traces to an 1818 settlement, and its 1930 Grand Trunk Western Railroad Depot -- a Tudor Revival building on the National Register of Historic Places -- anchors a district full of construction that predates residential central air by a wide margin.
A Downtown Rebuilt Around Rail Corridors, Not Duct Runs
