Living room with a sculptural fireplace, curved seating, and floor-to-ceiling windows overlooking the city skyline in a Fifth Avenue penthouse.

Fifth Avenue Penthouse

This Fifth Avenue penthouse apartment underwent a complete interior demolition and redesign. The new layout replaces compartmentalized rooms with a unified open plan, emphasizing continuity and natural light. Storage is integrated into wall assemblies, and sliding elements enable flexible spatial division. Window openings were resized to achieve proportional consistency and optimize daylighting. To connect the residence to a new, second-floor addition, 1100 Architect designed a custom, sculptural interior stair.

Minimal living room organized around a central fireplace and round coffee table, with seating arranged symmetrically.
