The program brief Karp took on for this project: To design a contextual tower adjacent to a historic low-rise apartment building--designed by an architect who once worked for Meyer Lansky. Finally, we hear how the building has played a role in a broader urban-planning initiative in Miami Beach--opening up access to Biscayne Bay. Karp's own favorite detail: The way the twisting tower evokes the torque of a sailboat. He also explains how his designs encourage outdoor living-especially on the deluxe penthouse levels.
