Description

Three Bedroom, Two and a Half Bath Fitzroy Townhouse Residence with Two Private Outdoor Spaces & Rooftop Rights Introducing Residence D, an extraordinary three bedroom home within the historic Fitzroy Townhouses, set on one of Chelsea's widest and most storied blocks. This 22 foot wide residence combines the scale and soul of a classic brownstone with the ease of co op living, moments from the High Line, Chelsea's world renowned galleries, and The Avenues School. A standout in every season, the home offers two exceptional private outdoor spaces: a large south facing terrace off the parlor level and a private roof terrace, along with additional rooftop development rights. The newly tiled south facing terrace creates a peaceful outdoor retreat overlooking the treetops and gardens of neighboring townhouses. Above, the roof terrace features a large dining table, dozens of thriving potted plants, and panoramic views stretching from the Hudson River to the Empire State Building. It is an exceptional setting for entertaining or quiet mornings above the city. Inside, high ceilings and beautiful exposed wood rafters bring warmth and architectural character, while a washer and dryer, excellent closets, and thoughtful storage provide the practical comforts of everyday living. The open chef's kitchen features Brazilian Yellow River marble countertops, custom cabinetry, built in spice racks, clever storage, and high end appliances including a Liebherr refrigerator, Fisher & Paykel range, and double drawer dishwasher. The gracious main living level is anchored by a marble wood burning fireplace, with enough scale for a grand piano and an eight seat dining table. A powder room and ample storage complete the level. Upstairs, two sun filled bedrooms offer generous closets and share a renovated bathroom with Mediterranean inspired tilework. At the top of the residence, the private primary suite offers exceptional seclusion, a skylight, and direct access to the expansive roof terrace. 434 West 23rd Street, Residence D, is where artistry meets architecture and historic townhouse character meets comfortable modern living. It is a distinctive Chelsea home designed for entertaining, relaxing, and living well.
