First time available in nearly 50 years. Located on Chelsea's coveted Seminary Row, this authentic one-bedroom apartment is one of just seven residences in an Italianate brownstone built in 1856. Owned by the same family for nearly half a century, the apartment retains the warmth, scale, and architectural character that make historic Chelsea brownstones so enduringly desirable. Just two flights up, this charming one-bedroom enjoys both western and southern exposures, filling the home with warm light. Soaring 10-foot ceilings, original hardwood floors, and a beautifully preserved fireplace create an inviting living space that feels both elegant and comfortable. The entry foyer with two closets provides excellent storage, while the bedroom offers a step-in closet, overhead storage, and a windowed bath. An additional private storage unit transfers with the apartment. The apartment is being offered in as-is condition, presenting an exceptional opportunity for a purchaser to restore, update, or personalize the home while preserving its authentic prewar character. Please note that some images are virtually staged. Located on Seminary Row, one of Chelsea's most picturesque blocks, you're just one block from the High Line and moments from Chelsea's renowned galleries, restaurants, cafés, Chelsea Piers, Hudson River Park, and multiple subway lines including the A/C/E, L, and 1/2/3. The boutique, self-managed cooperative offers complimentary laundry, video intercom, and attentive shareholder stewardship. To preserve the character of the building, subletting, pied-à-terre ownership, co-purchasing, and gifting are not permitted. Apartment 7 may also be purchased together with Apartment 9, located directly above, creating a rare opportunity to combine two residences in one of Chelsea's finest historic brownstones. Please contact the exclusive listing agents to schedule a private showing.
