Originally built in 1881 by James White, 67 Franklin Street represents one of New York’s most stunning examples of 19th-century cast iron architecture. The landmark building’s neoclassical façade rises six stories, with intricate ornamentation that shifts subtly from one floor to the next. In reimagining the 13-unit building, architect Shigeru Ban respected its historic detailing, but re-envisioned its interior volumes and created two glass and steel penthouses that represent the height of contemporary living.(castironhouse.com)
