1028 Flagler Avenue A CASA MARINA ORIGINAL. Some houses capture a moment in time. Others seem to have understood, from the beginning, what makes Key West such an extraordinary place to live. Built in 1958, 1028 Flagler Avenue is a striking example of tropical mid-century modern architecture, set within a private three-building compound on 11, 586 square feet in Casa Marina, one of the island's most distinguished neighborhoods. Behind substantial privacy walls lies a world of its own. Winding pathways lead through lush native and tropical gardens that seem borrowed from a movie, connecting the main residence, separate two-bedroom guest quarters, and detached garage/workshop. Mature palms, flowering gardens, shaded terraces, and a custom swimming pool create an extraordinary sense of seclusion. Inside, clean architectural lines, high ceilings, and generous proportions celebrate indoor-outdoor living. Expansive living and dining areas, a library, and a separate study offer room to gather or retreat. Impact-rated windows and doors provide modern peace of mind without sacrificing the home's character. The guest quarters include their own living area and kitchen, ideal for family and visitors. Together, the three buildings offer 3, 589 square feet of combined enclosed space: 3, 173 square feet of living area plus a 416-square-foot garage/workshop. Covered outdoor dining, an outdoor kitchen, and abundant off-street parking make this compound as practical as it is beautiful. Just two blocks from Higgs Beach and the Atlantic Ocean, with White Street Pier, waterfront parks, tennis, pickleball, and some of Key West's best-loved restaurants close at hand. Old Town is minutes away, yet the privacy and tranquility of Casa Marina remain entirely your own.
