3739 Collins Ave Ph601/603 Casa Mar combines the privacy and outdoor living of a beachfront home with the services and security of a luxury boutique oceanfront building. The combined southeast-corner penthouse offers four bedrooms, four and a half bathrooms and 3, 357 square feet of interiors, plus a rare 3, 500-square-foot private rooftop with a kitchen, stone bar, pergola, entertaining areas and panoramic ocean views. Curated by cultural placemaker Ximena Caminos, with architectural consulting by Galia Solomonoff, the residence features soaring ceilings, multiple oceanfront balconies and white marble floors. Details include hand-painted murals by Argentine artist Augusto Falopapas, a champagne-mirrored ceiling and a pink-onyx kitchen with white-oak cabinetry and rose-gold hardware. The primary suite includes a spa-like bath and custom dressing room. Originally designed in 1941 by noted Art Deco architect L. Murray Dixon, The Caribbean offers direct beach access, beach and pool service, an infinity pool, spa, and cabanas. Located on Miami Beach's iconic Millionaire's Row near the Faena District, The Miami Beach EDITION and Soho Beach House, with Casa Cipriani Miami Beach and Aman Miami Beach joining the neighborhood, Casa Mar is a singular opportunity to own a private retreat in one of Collins Avenue's most architecturally significant boutique oceanfront buildings.
