Manhattan Penthouse Gallery

Manhattan Penthouse Gallery

A full-floor duplex penthouse overlooking Central Park with floating bronze stairs.

Commanding prime panoramic views of Central Park from the 64th and 65th floors of a newly erected Manhattan tower, Manhattan Penthouse Gallery is a masterclass in custom residential luxury interior architecture. Spanning 7,800 sq ft, the duplex was conceived as a private sanctuary for a prominent hedge fund founder and art collector.

The centerpiece of the home is a sculptural floating spiral staircase fabricated from a single continuous ribbon of hand-patinated architectural bronze. Each cantilevered step is wrapped in smoked European oak with integrated recessed LED grazers, appearing to float effortlessly through a double-height 24-foot glass atrium overlooking the park.

Acoustic & Haptic Material Curation

The interior architecture balances monumental scale with intimate tactile comfort. Walls are finished in hand-burnished Roman clay plaster; floors feature 14-inch wide engineered smoked French oak planks laid over dual-layer acoustic dampening membranes. In the primary bath, a 12-foot continuous vanity carved from rare Breccia Capraia marble is complemented by custom unlacquered gunmetal plumbing fixtures.
