Description

West Chelsea Duplex with South-facing Private Roof Deck.

Perched atop the historic Fitzroy Townhouses, this sun-drenched duplex offers a singular living experience on one of Manhattan's most storied blocks. Treetop views unfold through three oversized north-facing windows, casting a quiet, luminous light across the living and dining expanse below. This impeccably maintained home opens to a gracious living and dining area. The adjacent chef's kitchen is thoughtfully renovated with marble surfaces, Sub-Zero and Viking appliances, and a wine refrigerator for effortless entertaining. A wood-burning fireplace anchors the main level alongside generous built-ins, and the kind of prewar detailing that simply cannot be replicated. Additionally, there is a powder room, for your convenience. Upstairs, the private quarters are a haven. The primary suite offers an abundance of custom closet space, a workspace, and a second wood burning fireplace - a rare luxury. Additionally, there is a well-proportioned second bedroom. A large bath with a double vanity and a Miele laundry complete the upper level. The crown of this residence is its expansive, south-facing private 450 sq ft roof deck - an open-air retreat bathed in all-day sun, with views across landmarked townhouses and the vibrant West Chelsea skyline. Upgraded decking, additional storage, and dedicated refrigeration make it both functional and sublime. It serves as a true outdoor retreat. Apartment E isn't just an apartment; it's a sanctuary.

This boutique cooperative, dating to 1855, has recently undergone a meticulous building-wide renovation, the building's refinement begins at the manicured garden entrance, leading into a sophisticated new lobby secured by state-of-the-art technology including a digital doorman.

434 West 23rd Street is part of the historic Fitzroy Townhouses, built on land that once belonged to Clement Clarke Moore. Moments from the High Line, West Chelsea Arts District, Chelsea Market, Whitney Museum, Hudson Yards, and the Meatpacking District.
