Spanning more than 3,000 square feet, this four-bedroom residence underwent a multi-million-dollar renovation, during which it was completely stripped down and reimagined with extensive structural and top quality upgrades, even the wall studs were reinforced. The result is a home that exceeds the construction standards of most conversion condominiums in Manhattan. While the décor is elegant and easily customized, the true value lies in the infrastructure: all-new electrical wiring, two upgraded electrical panels, and fully replaced PTAC units, which are regularly serviced by LTB Mechanical. All bathroom plumbing was also replaced in full. Every interior door is crafted from custom hardwood millwork, while the original front door was preserved and paneled on the interior to match, giving it the heft and presence of a traditional old-house entrance. Rockwool insulation was added to interior walls to provide soundproofing, fire resistance, non-toxicity, and thermal regulation. Real hardwood floors were installed throughout. As a result, the apartment offers the solidity and acoustic integrity of a plaster-walled home. Crown moldings were deliberately chosen for their simplicity, cove profiles that suit the ceiling heights, but made of plaster in all rooms except the living room, ensuring they will never crack or separate over time. Architectural upgrades include mirrored pilasters in the gallery, cleverly concealing structural beams. Light was a key design priority. With three exposures, an uncommon feature in a Park Avenue apartment, natural light fills the home throughout the day. From the living room, one can see directly into the dining room, which is open and airy thanks to the adjacent gallery and the nearly 25-foot-long living space beyond. To further enhance the light, two pairs of French doors and the kitchen door were mirrored, brightening the dining area. The primary suite evokes the tranquility of the countryside whilst in the heart of the city and is filled with soft natural light throughout the day. The oversized primary bath features a walk-in shower, a separate soaking tub, and refined finishes that create a serene, retreat-like atmosphere. Large squares of Thassos marble were meticulously cut and laid with minimal grout joints, ensuring precise alignment and a clean, elegant look. There are three secondary bedrooms, each with an ensuite bathroom. Very ample storage throughout the apartment is smartly integrated. In the water closet, jib-style doors are wallpapered to blend seamlessly into the walls, and the medicine cabinets feature hidden electrical outlets. In the kitchen, custom cabinetry conceals the microwave and toaster oven, while the range hood is also fully custom, blending form with function.
