Extell Development Company presents The Carlton House, 21 East 61st Street.
Located in one of the most coveted neighborhoods on the Upper East Side, The Carlton House has been transformed into 68 exceptional residences. Reinterpreted and transformed to the highest standards of the 21st century, these luxury homes sets a new standard of excellence for premier developments in Manhattan, further enhancing Extell’s long-standing reputation for building quality properties. With only one remaining sponsor residence left, this is the last opportunity to own a home in this new development.


The brick and limestone exterior of The Carlton House has been meticulously preserved and restored to its original gracious appearance. Handsome new windows and terrace doors offer the latest in beauty, functionality and energy efficiency. The Carlton House consists of 16 floors of newly transformed luxury homes inclusive of a two-story addition at the roof of the building, which crowns The Carlton House with a spectacular penthouse residence. An impressive five-story townhouse with roof terrace is located adjacent to the building at 19 East 61st.


The Carlton House offers peerless personal service on a 24-hour basis. A uniformed doorman and concierge greets guests in the well-appointed Lobby. A dedicated lifestyle consultant is available to provide personalized services and assist residents with a range of needs from dining and entertainment reservations to travel accommodations and private event planning.

Finely Crafted Interiors

Interiors of superior design and construction have been envisioned by the internationally recognized team at Katherine Newman Design, one of Architectural Digest’s “Top 100” interior design firms. Inspired by the rich materiality of early 20th century Art Deco and Moderne design, The Carlton House resonates with the classic and enduring style of its iconic location on Manhattan’s Gold Coast. Fine exotic materials, hallmarks of Moderne design, are utilized extensively and with great artistic skill throughout a series of beautifully crafted common areas. The articulated millwork that defines each space allows for a sequential layering of complementary finishes to create a rich and harmonious whole. Stitched leather wall panels in the Reception Hall and macassar ebony in the concierge Lobby contrast with the soft shimmer of reverse painted glass panels in adjacent corridors. These subtle and luxurious finishes form the backdrop for two custom designed installations—a marble marquetry wall and a sculptural concierge desk— that recall the Moderne movement’s signature trait of championing art and culture through interior design.
