To encourage these transformations, New York State approved the 467-m tax incentive program in 2024, offering tax exemptions of up to 35 years for projects that convert non-residential space into housing and include required affordable units. Marc Holliday, chairman and CEO of SL Green, told The Real Deall that he expects 20 to 40 million square feet of office space could ultimately convert to residential under the program.

RYBAK Development is expanding its Manhattan portfolio with a new boutique condominium at 218 Madison Avenue (23 East 36th Street) in Murray Hill, following successful projects such as 500 East 81st Street and 660 Lexington Avenue. Rising at the northwest corner of Madison Avenue and East 36th Street, the 11-story building will contain 25 residences, including a penthouse, and is scheduled for completion in late 2026. Designed by IMC Architecture, the project will feature a limestone façade with bronze-accented floor-to-ceiling windows and landscaped street frontage, with its primary entrance located on East 36th Street.
The development replaces a historically layered structure that once served as the residence of Archbishop John Hughes, New York’s first archbishop, and later housed Archbishop John McCloskey, the first American cardinal. According to Daytonian in Manhattan, during the 19th century, the mansion functioned as a planning center for the construction of St. Patrick’s Cathedral and hosted early discussions about expanding Catholic education in New York. Over time the building was heavily altered, serving variously as a club for “self-supporting women,” publishing offices, and small commercial spaces before ultimately losing much of its architectural significance. After acquiring the site in 2023 for $12 million, RYBAK demolished the structure and began construction on the new condominium.

Continuum Company has topped out construction on a new 18-story condominium at 40 East 35th Street that will deliver 137 residences to a midblock site between Park and Madison Avenues, a block south from The Morgan Museum and Library. Designed by SLCE Architects, the roughly 180,000-square-foot project will also include ground-floor commercial space, a residential courtyard, community facility space, and a 17-car parking garage. The development replaces several historic structures, including the Community Church of New York, a congregation dating to 1825 that hosted figures such as Pete Seeger, Nelson Mandela, and a famous debate between Malcolm X and Bayard Rustin The property was sold to Continuum in 2022 for approximately $66 million.
Once complete in 2027, the building will introduce a sizable condominium offering to a quiet Midtown block within walking distance of Grand Central Terminal, Bryant Park, and Midtown’s office core. While surrounding buildings will limit far reaching views, residents will benefit from its proximity to transit, cultural institutions, and easy commutes. Sales are expected to launch later this year.

Once completed, the development will introduce a major new housing component to East Midtown, with residences expected to range from studios to three-bedroom apartments. Plans also call for amenities such as a rooftop pool, fitness center, and other shared spaces, helping reposition the formerly corporate complex as a full-time residential community. The project reflects a broader push to convert underused office buildings into housing and is expected to deliver new apartments to the market beginning in 2027, contributing to the ongoing transformation of Midtown into a more mixed-use, 24-hour neighborhood.

According to an early report, this project will bring the most units to Murray Hill since 2019. However, it will be some time before it is delivered: Demolition has started on one of the low-rise buildings in the assemblage, and work has been slow.

The site has seen multiple iterations over the years, including a previously proposed consulate tower that is no longer moving forward. According to Dayton in Manhattan, the block was historically occupied by a mix of small-scale industrial and residential buildings, including the former J.F. McQuade printing building and a Civil War–era wooden house once home to a family-run grocery and undertaking business.

In the months that followed, plans for a giant Ferris wheel on the site were nixed, and the developer sought to sweeten the deal by promising that the residential component would include 513 permanently affordable units priced at an average of 80% or below the average median income. Later, they promised that all 1,080 of the planned housing units would be affordable. However, the plan was ultimately rejected in September 2025, and Soloviev Group's new plans for the site are not known.
