Experience refined grandeur in this 1,100-square-foot one-bedroom, one-bath home — a showcase of Piet Boon’s signature craftsmanship and understated elegance. With soaring 11.5-foot ceilings, luminous eastern exposures, and dramatic casement windows framing views of Park Avenue South’s tree-lined charm, every moment here feels expansive and inspired.

Curated with a luminous, natural palette, the residence features 6-inch brushed oak plank flooring, original beam ceilings, and bespoke millwork that speaks to uncompromising quality. From the custom-framed closet doors to recessed-paneled interiors with concealed hinges, no detail has been overlooked. Thoughtful touches such as Formani stainless steel hardware and automated solar shades with hidden pockets reflect the seamless integration of design and technology.

The sleek Bulthaup kitchen defines modern sophistication — outfitted with Alpine White cabinetry, a 3-inch Chambolle stone countertop and backsplash sourced from Belgium, and a full suite of integrated Miele appliances, including wine cooler and concealed hood.

The primary suite is a private sanctuary of calm, where soft textures and natural materials foster serenity. The ensuite bath, wrapped in Chambolle stone slabs with radiant heated floors, features a luxurious walk-in shower and convertible pocket doors allowing a graceful transition to a powder room when entertaining. Every fixture — from Dornbracht fittings to Piet Boon bathware — speaks to an unrelenting pursuit of perfection.

Every inch of Residence 4A reflects an extraordinary balance of artistry, precision, and warmth — a testament to modern luxury reimagined.
