This steampunk home gym occupies a railcar-like shell clad in riveted copper with gunmetal steel framing and bold brass hardware. Black rubber flooring is split by a polished brass center strip guiding the layout of benches, a barbell rack draped with heavy chains and a pocket-watch timer, and an air bike with a leather-strapped fan. Warm cage sconces and skylight panels cast amber light through hints of steam, heightening the patina of aged metals and the mechanical mood.
