L’Excellence is a 24-story oceanfront condominium at 5757 Collins Ave, in Miami Beach’s Millionaire’s Row corridor. Completed in 1991, the association sought to modernize exterior openings—impact windows and large-format sliding glass doors—while preserving panoramic Atlantic and skyline views and meeting Miami-Dade hurricane and water-infiltration performance requirements.Miami ResidentialCompass
