Cooperativa Chelsea

434 West 20th Street, a 25-foot-wide Italianate brownstone built in 1856, is located on one of Chelsea’s most picturesque, tree-lined blocks within the Historic District, directly across from the beautifully landscaped gardens of the General Theological Seminary.

This bright, top-floor one-bedroom home features 10-foot ceilings, a skylight, and two west-facing windows that fill the space with natural light. The open kitchen offers generous cabinet and counter space, along with a convenient breakfast bar. A wood-burning fireplace adds warmth and character to the living area.

French doors lead to a tranquil bedroom with southern exposure, treetop views, a walk-in closet, and additional storage. The en-suite marble bathroom also enjoys southern light and features a windowed shower.

A spiral staircase leads to a truly exceptional private roof terrace-nearly the size of the apartment itself and a rare find in Chelsea. This expansive outdoor oasis offers sweeping skyline views, with ample space for dining, lounging, and entertaining. Fully furnished and equipped with electricity and water, it serves as a seamless extension of the home-ideal for everything from quiet mornings to sunset gatherings.

Additional features include split-system air conditioning, two entry closets, a mudroom area, and a dedicated basement storage unit.

This boutique, self-managed seven-unit walk-up co-op is well maintained and offers a video intercom system and a laundry room with complimentary washer and
dryer. As a small, shareholder-run building, policies are in place to preserve its intimate character; subletting, pied-à-terre ownership, co-purchasing, and gifting are not permitted. 80% financing allowed.

Can be combined with Unit 7 on the floor below, which is also available for sale.
