Overview of The Gemstone at 235 West End Avenue

The Gemstone is a 17 story pre-war condominium at 235 West End Avenue, built in 1928 by Bing & Bing and converted to condominiums in 1987. The handsome yellow brick building houses 184 apartments and features a two story entrance surround with canopy, arched windows with columns on the second floor, and a well appointed lobby. Actor Peter Riegert has called the building home.

Apartments retain classic pre-war details including high beamed ceilings, original hardwood floors, and arched doorways, with many units featuring windowed kitchens and bathrooms. Renovated apartments typically showcase marble countertops and bathrooms, stainless steel appliances, and generous closet space. The building's penthouse units offer private terraces, with one featuring a 45 foot by 9 foot outdoor space with river views. Most units have multiple exposures and abundant natural light.

Residents enjoy a 24 hour doorman, live-in superintendent, fitness center, and a landscaped roof deck with Hudson River views. Additional amenities include a laundry room, bike storage, private bin storage (waitlisted), and a children's playroom. The building permits protruding air conditioners but has no garage.

Located between West 70th and 71st Streets, The Gemstone sits one block from the 1/2/3 subway lines at 72nd Street and offers easy access to both Riverside and Central Park. Lincoln Center, Trader Joe's, Fairway, Zabar's, and Citarella are all nearby. The building welcomes pets (one per unit), allows pieds-à-terre and investors, and permits up to 90% financing.
