Contemporary Miami Beach interiors are instantly recognizable by their sleek white finishes and bold accents of color. Yet “they didn’t want typical,” architect Joe Yacobellis, a senior associate at Mojo Stumer Associates, says of a husband and wife who purchased a spec condominium unit in the city. The New York–based design firm gutted this 4,700-square-foot vacation residence, reconfiguring the plan of the penthouse and combining concrete, blackened steel, and oak with white marble and lacquered surfaces. “An industrial-inspired space was always part of their vision, and we also wanted them to recognize where they were,” Yacobellis says of the material selections. “The overall goal was to marry New York and Miami.”

The primary bath is emblematic of the project’s transformative ambitions. This space hugs the terrace-wrapped north elevation of the mid-rise building, where the kitchen originally stood. To accommodate necessary plumbing, Mojo Stumer installed a platform above the concrete superstructure and connected this new raised space to the primary bedroom via two steps clad with sintered stone. Tucked behind the bedroom’s oak accent wall, a custom blackened-stainless-steel and wire-glass pocket door slides out to distinguish the sleeping from the bathing areas.
