Property Description for 434 West 20th Street, 9

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.

Chelsea | Manhattan

Quick Profile

The row houses portray the world-class architecture of Greek Revival, Italianate and Georgian styles. The population is both ethnically and socially diverse, which is reflected in the restaurants and retail businesses in the neighborhood. 

Western Chelsea is the center of the NYC art world, where you will find more than 200 art galleries housed in rehabbed factories and warehouses, as well as in newly-constructed buildings.

While people of many different cultures call Chelsea home, it has been a mecca over the years for people in the LGBTQ community. One census reported that as many as 22% of its residents were gay couples. Eighth Avenue is a trendy area for LGBTQ-oriented dining and shopping. Although it no longer draws the LGBTQ population that it once did, Chelsea still has many popular alternative bars.  

Chelsea is primarily residential, consisting of a mixture of diverse complexes, low-rise apartment blocks, tenements, townhouses, renovated row houses, and luxury high-rises. 

Chelsea is an interesting and sought-after place to live, with unique clothing boutiques, restaurants, and delis representing cultures from around the world. In addition to its quirky establishments, Chelsea has fine dining restaurants and a vibrant, hip nightlife, which adds to its allure.

Chelsea is well-served by public transportation. At least six city bus routes traverse Chelsea. There are three NYC subway routes with stops on Seventh Avenue, three on Eighth Avenue, and two more on Sixth Avenue. The 34th Street - Hudson Yards Station opened in 2015 with its main entrance in Chelsea.
