Miami style: Miami Modern / Tropical Modern, with an Art Deco revival streak
Miami mixes three local traditions: 1930s Tropical Deco, the 1950s Miami Modern (MiMo) of Morris Lapidus, and today's tropical modern, where clean geometry meets deep overhangs, glass and lush planting. Interiors stay cool and open to the outside, with terrazzo, white plaster, bold color accents and glossy finishes.
Work by Miami designers first, then the styles Miami draws from.
