Originally, this duplex, located in one of Park’s Avenue earliest luxury apartment buildings designed by Delano & Aldrich in 1907, had closed-off rooms, Colonial Revival details and a series of small servants’ quarters on the upper floor. To create a modern, comfortable and technologically up-to-date living space for a large family, PPA reworked the plan and emphasized a stripped abstracted aesthetic to make the rooms feel open, streamlined and sophisticated. Eve Robinson’s decoration compliments the crisp minimal expression of the interiors and the owner’s collection of photography and sculpture. PPA transformed the staff quarters into a new upstairs playroom and created a substantial master suite out of small bachelor’s simplex that was added to the apartment.
