This past summer, developer Related Companies announced that its towering Upper East Side rental The Strathmore is being converted into for-sales residences. The prominent high-rise soars confidently from the southeast corner of First Avenue and East 86th Street, a short distance from the still immaculate (relatively speaking) Second Avenue Subway.
Now, as we're in the midst of the brisk Fall selling season, sales have quietly launched, with one-bedrooms starting from $945,000, two-beds from $1,555,000, three-beds from $2,795,000, and four-beds from $4,750,000. Prices blend to average price/ft2 of $1,432, a fantastic bargain for the neighborhood, especially when compared to nearby new developments which typically trade over $2,000 a foot.

Furthermore, a half-dozen penthouses will crown the 43-story, 450-foot-tall building, which even after its 1996 completion remains one of the tallest buildings on the Upper East Side. These perches will offer panoramic views of the east side and Manhattan skyline, stretching from the East River to Central Park.
The Strathmore (not to be confused with the Riverside Drive building seen on The Marvelous Mrs. Maisel) was designed by the prolific firm of Costas Kondylis & Partners, the architects behind many of the Riverside Boulevard towers, The Laurel, and several Trump properties include Trump World Tower which opened in 2001 as the tallest residential building in the world.
The Strathmore from First Avenue
The Strathmore's facade is a Post-Modern affair of oversized bay corner windows, orange and beige brick, and an articulated crown with a concealed mechanical bulkhead/water tower. The tower sets back from both First Avenue and East 84th Street, rising nearly sheer, with curved windows softening its corners, and expanses of brick that attempt to contextualize the design with its walk-up and mid-rise neighbors on the block.
While a selling point for those within, the building's height was quite controversial. As this 1996 The New York Times article details, while it was under construction, the city passed more restrictive zoning laws to prohibit such tall, slender buildings between York and Third Avenues, and between East 57th and 96th Streets. As a result, residents are all but assured of open views of the East River, Central Park, and/or the Manhattan skyline.
The 144 for-sale units are being offered for sale as cooperative apartments and are part of four leasehold condominium units that individually include the co-op units, a group of 36 rental units not being sold, a retail unit, and a parking garage. This structure of ownership, where an apartment corporation is the owner of, or has an ownership interest in, a condominium unit is commonly known as a “condop”.

While the units' sticker prices can be a little lower than their condo counterparts, monthly fees can be higher. However, despite its many amenities and services, monthly maintenance fees at The Strathmore appear to be in-line with many of its new development counterparts thanks to the building's size. One-beds will have monthlies starting around $2,300, and two-beds' will start at around $3,400. Furthermore, condops tend to offer less restrictive policies compared to co-ops, like no or fewer board approvals, less stringent policies about subletting, and friendlier attitudes towards parents buying for children, international buyers, and pet ownership.
The Strathmore's interiors will be reimagined by Ingrao Inc., whose founder, Tony Ingrao, designed Related Companies chairman Stephen M. Ross' former residence at One Central Park; Mr. Ingrao's portfolio also includes 35 Hudson Yards. Amenities like an indoor pool, a squash court, a fitness center, a children's playroom, and an entertainment lounge are likely to get similar upgrades.

The Strathmore also offers on-site parking, but is located a short distance from the East 86th Street Q train and the 90th Street ferry terminal, two transportation options that weren't available when the building opened in the late 1990s. Residents would have had to walk further west to the local and express 4/5/6 trains at East 86th Street. The Strathmore is also situated two blocks west of Carl Schurz Park and in close proximity to AMC Orpheum 7 movie theater and popular Upper East Side dining, not to mention supermarkets like Whole Foods and Fairway.
The Strathmore is located ten blocks south of Carnegie Park Condominium, which was originally developed by Related Companies as a rental building in 1986. The developer converted it to condos in 2014, and buyers have flocked to this Upper East Side building with a distinctive curve, high-end interiors, thoughtful indoor/outdoor amenities, and close proximity to Central Park and Museum Mile. Current public availabilities range from a studio for $995K to a two-bedroom for $1.499 million.
More recently, Related Companies embarked on successful rental-to-condop conversions in Lower Manhattan that include 450 Washington Street in Tribeca and Tribeca Green in Battery Park City. They are located near The Solaire and River & Warren, two other recent and successful rental-to-condop conversions.
