Open House New York (OHNY), the annual event that opens closed doors of the coolest, most obscure, and most architecturally interesting buildings in the city to the public, will be held the weekend of October 18th. Reservations for the tours (which take place in all five boroughs) are open starting October 8th at 11 a.m. here; the full lineup will be announced on October 1st, but you can get a preview of what's popping open below.

Some of the highlights of this year's event include new buildings and projects completed this year (25 Kent, Fotografiska, The Equitable Building at 120 Broadway), returning favorites (Ford Foundation Center for Social Justice, United Nations Headquarters), special programming (Factory Friday, Open Studios, Brooklyn Navy Yard) and a special design presentation and performance at the new TWA Hotel. Here are some of OHNY's picks:

The Equitable Building


  • 277 Mott, a new ground up core and shell project by Toshiko Mori Architect with a twisting front facade that appears to shift to approaching pedestrians. 
  • 25 Kent, the first commercial building of its type erected in North Williamsburg in more than 40 years. Designed by Hollwich Kushner, with Gensler leading design development, it includes an expansive rooftop with 360-views of the city and beyond. 
  • Center for Fiction, the only nonprofit organization in the U.S. solely dedicated to celebrating fiction, whose new headquarters designed by BKSK Architects houses 70,000 titles, a bookstore, an auditorium, and workspaces.
  • Crown Shy,  the restaurant designed by MNDPC with three floors of kitchens, dining rooms, and a bar. The 125-seat restaurant is hidden in plain sight of the ornate Art Deco lobby of 70 Pine Street behind an unassuming glass door. 
  • The Equitable Building at 120 Broadway, the Beaux Arts masterpiece that spans an entire city block and inspired the creation of New York City's 1916 Zoning Code, with a $50 million renovation by Beyer Blinder Belle Architects & Planners. 
  • Fotografiska, the first international outpost of Stockholm-based photography destination at the historic 281 Park Avenue South, renovated by CetraRuddy Architecture.
  • Pier 35, the new eco-park by SHoP Architects and Ken Smith Workshop that anchors the northern boundary of the East River esplanade project with an innovative habitat restoration prototype. 
  • The Spur High Line, the last section of the original High Line rail structure to be converted into public space. Daytime tours will be led by James Corner Field Operations and evening lighting tours by L'Observatoire International.

Ford Foundation


  • City Hall, one of the oldest city halls in the nation still serving its original government functions. In addition to the stunning rotunda, visitors will also be able to see the City Council Chamber and Governor's Room.
  • DSNY M 1/2/5 Garage and Salt Shed, the award winning Department of Sanitation facility home to three district garages with over 150 sanitation vehicles; fueling, repair, and vehicle wash facilities; and 5,000 tons of salt. 
  • Ford Foundation Center for Social Justice, the modernist icon by Kevin Roche John Dinkeloo and Associates returns to OHNY Weekend after a multiyear renovation by Gensler. 
  • Manhattan Borough President's Office Map Display, the only time the complete set of 92 Randel Farm maps of 1820, one of the most important documents in New York City history, are displayed in full.
  • Modulightor, home to the Paul Rudolph Heritage Foundation, the building features intricately interwoven horizontal and vertical spaces and rich displays of worldly objects.
  • Newtown Creek Wastewater Resource Facility, the largest of New York City's wastewater treatment plants, designed by Ennead Architects. 
  • United Nations Headquarters, where visitors will learn about the history of the organization, its architecture and artwork with stops in the Plaza, and General Assembly Lobby. 
  • Woolworth Building, the "Cathedral of Commerce" by architect Cass Gilbert whose design changed the face of engineering for decades that followed. 


While a majority of the events are Open Access, meaning you don't need a reservation and can just drop by, some of the more intriguing ones are capped with limited capacity, so you'll want to check out the OHNY website on October 8th to make sure you don't miss out on any opportunities. Tickets for these typically go FAST. There will also be a fundraiser launch party on October 17th at 25 Kent, with food, drinks, and entertainment—you can get tickets for that here.
