OHNY Weekend

For this year’s OHNY Weekend, Open House New York partnered with Wikimedia NYC to present the Wikipedia @ OHNY Weekend Photo Competition. Weekend visitors were invited to submit photos via Wikimedia Commons for a chance to win prizes, and at the same time contribute to one one of the largest collaboratively compiled and edited media projects in history. 1,100 photos were submitted, all of which are now part of Wikimedia Commons, the online repository of free-use public domain images that are used across Wikipedia. A select number of photos taken during OHNY Weekend are already being used to illustrate Wikipedia articles! Click here to view a list of these photos and the articles in which they appear.

For the photo competition, submissions were grouped into three categories–Details, Exteriors, and Interiors–and judged by a panel of jurors including Pat Kiernan, Morning Anchor, NY1; Roy Kim, President, Open House New York Board of Directors; Alexandra Lange, Architecture Critic, Curbed; and Erica Stoller, Director, Esto. Winners were selected in each category, one of which was selected as the Grand Prize Winner. In addition, 3-4 photos in each category were recognized with an Honorable Mention, determined by the number of votes from the panel of jurors. Prizes awarded to the winners include an iPad Mini and $100 certificates for Photo Safaris, courtesy of New York City Photo Safari.

Many thanks to all entrants and congratulations to the winners!

Tens of thousands of New Yorkers – along with visitors from across the country and around the world – came together this year for the 2015 Open House New York Weekend, crisscrossing the five boroughs in celebration of this extraordinary city and its architecture. From food production spaces to dazzling landmark interiors, the hills of Governors Island to a gilded Wonder Theater in Brooklyn, this year’s Weekend gave visitors unparalled access to the city, deepening our understanding of the complexities of design, construction, and preservation, and providing a visceral reminder of how thoughtful design can immeasurably enrich our day-to-day-lives.

Our deepest thanks to all of you who made it possible: all of our funders, including premier sponsor Porcelanosa, without whose support there would be no OHNY Weekend; our site hosts, intrepid individuals and organizations who opened their doors to welcome the public into their spaces; the record-breaking 1,200 volunteers who helped manage crowds with kindness and grace; and the tens of thousands of visitors who imbue this event with boundless energy and enthusiasm. It is truly a privilege to collaborate with all of you on this incredible festival.

View some of our favorite highlights here.



Tomorrow, on the Saturday of OHNY Weekend (Oct. 17), urban wonks will have an extraordinary opportunity to visit two of the most important buildings in New York City government: City Hall and the Manhattan Municipal Building. Open Access to City Hall has been organized by the Public Design Commission, the official design review agency that advocates for excellence and innovation in the city’s public realm. PDC officials will be on-site throughout speaking about the building’s stunning landmark interiors. And before or after you visit the seat of city government, don’t miss the Manhattan Borough President’s Map Display, just across Centre Street, for a truly historic display of the 1820 Randel Farm Maps, the first to plot the grid established by the Commissioners’ Plan of 1811.

City Hall

12:00 pm4:00 pm.

Completed in 1812, New York’s City Hall is one of the oldest City Halls in the nation still serving its original purpose. It is the third home of New York’s government, but the first to be built specifically as a municipal seat. It is a National Historic Landmark and an NYC Landmark, and the rotunda, lit by a central oculus and graced by a “floating” staircase, is an NYC interior landmark. The plaza, rotunda, City Council chamber, and Governor’s Room will be open during OHNY Weekend, and visitors will be able to chat with staff from the Public Design Commission and Richard Southwick, Director of Preservation with Beyer Blinder Belle. Long lines are expected, so arrive early!


M-Manhattan Borough Presidents Map Display

Manhattan Borough President’s Map Display

10:00 am4:00 pm.

NYC Borough Presidents are responsible for maintaining the official maps for their borough. On OHNY Weekend, the Manhattan BP Gale Brewer’s office will display an historically essential map in the development of Manhattan—executed by John Randel in 1820—that has never been displayed in full. This map is the first that plotted the 1811 “Commissioner’s Plan” which established the Manhattan street grid—from Houston St. to 155th Street—and also encompasses the rest of the island, from The Battery to Inwood. The MBP’s Topographical Bureau is the sole repository for these 92 individually hand-drawn and hand-colored panels— which will be assembled into a room-size display, roughly 16 feet by 60 feet.

For true map geeks, there’s a special incentive to arrive at the 10:00 am Saturday opening of the display: Hilary Ballon, curator of The Greatest Grid: The Master Plan of Manhattan at Museum of the City of New York (and Professor of Urban Studies at NYU) will be available to answer visitors’ questions, but only from 10:00 am11:00 am.

Dear Friends:

It is a great pleasure to send greetings to everyone attending the 13th Annual Open House New York Weekend.

As a hub of innovation and the arts, New York has a long and storied architectural history, and our city has always been at the forefront of advancements in the field of urban planning and design. The five boroughs attract some of the world’s leading architects, and their groundbreaking projects that range from the classic to the contemporary have become some of the most famous and widely recognized public spaces, skyscrapers, and cultural landmarks ever created.

With its ongoing mission to foster greater appreciation for our city’s distinct architectural landscape, OHNY has showcased the buildings and structures that have come to define New York, offering visitors and longtime residents alike the opportunity to see our urban environment in new and inspiring ways. As part of the annual OHNY Weekend, workshops, exclusive tours, and discussions will bring together engineers, architectural enthusiasts, and the public to celebrate achievements in construction. The event will also offer a chance to plan for the future with attention to the latest sustainable developments and projects that are helping move our city forward.

On behalf of the City of New York, I thank OHNY staff and volunteers for opening the doors of our buildings to inspire the next generation of urban designers and for paying tribute to the architectural legacy of the five boroughs. Please accept my best wishes for a memorable and enjoyable weekend.

The 1950s and 60s were a period of architectural experimentation, as new materials and technologies opened up a whole range of possibilities for architects and designers. At the time, New York City was in the midst of a post-war construction boom, and today the five boroughs are dotted with some truly amazing masterpieces of Mid-century Modernism. During OHNY Weekend, many of the very best examples from this period will be open to the public, free of charge. From Marcel Breuer’s campus buildings in the Bronx, to Philip Johnson’s very first commission, to a slew of landmarks from the 1964-65 World’s Fair in Queens, fans of Mid-century Modernism (which has been having a moment of late, thanks to the TV show Mad Men) should find this year’s lineup particularly enticing. All of the sites listed below are Open Access during the times and dates indicated below, and do not require reservations.

Ford Foundation

Saturday, October 17: 10:00 am – 2:00 pm.

Designed by Kevin Roche John Dinkeloo and Associates, this building’s soaring 12-story atrium looks out over a lush, terraced garden. Though interior spaces built as late as 1985 are eligible for landmark status, the Ford Foundation’s atrium, completed in 1967, is currently the “youngest” interior landmark in the city, and is considered one of the most iconic Mid-Century Modern interiors in the five boroughs. During OHNY Weekend, visitors will have the rare opportunity to travel up to the balconies overlooking the garden to experience the space from above.



Four Seasons Restaurant

12:00 pm4:00 pm.

The Four Seasons has a storied history as the original home of the New York “power lunch,” and is known the world over for its innovative design by Philip Johnson. In fact, it was the famed architect’s first major commission. Visitors will be able to take in a unique view of the surrounding streetscapes through the restaurant’s beloved shimmering chain curtains, and explore the Pool Room, with its four trees that change with the seasons, as well as the Grill Room, with its two iconic Richard Lippold sculptures. An exhibition of images of landmark interiors by photographer Larry Lederman, featured in the new book Interior Landmarks: Treasures of New York, will also be on view.

Japan Society

Saturday & Sunday, October 17-18: 11:00 am5:00 pm.

Built on land donated by John D. Rockefeller 3rd, Japan Society’s building was designed by architect Junzo Yoshimura and opened in 1971 as the first building by a leading Japanese architect in New York City. Located near the United Nations on 47th Street, activities at Japan Society are set against a stunning backdrop of indoor gardens, a reflecting pool and a waterfall. The building is furnished with a superb collection of tables, chairs and benches designed by master woodworker George Nakashima. Tours will be offered on both days of OHNY Weekend, free of charge.

TWA Flight Center

Sunday, October 18: 11:00 am – 3:00 pm.

One of the most famous icons of Mid-century Modernism, the TWA Flight Center, is on the National Register of Historic Places. MCR Development, the firm selected by the Port Authority to celebrate Saarinen’s masterpiece and reopen it to the public, is advancing a privately-funded $265 million plan to rehabilitate the national landmark to its original splendor and deliver the first on-site, world-class airport hotel at JFK International Airport. Expected to be complete in 2018, the redevelopment plan will include a museum focusing on New York City as the birthplace of the Jet Age, the storied history of TWA Airlines, and the Mid-century Modern design movement.



World’s Fair Pavilions

New York Hall of Science—Saturday & Sunday, October 17-18: 10:00 am – 2:00 pm.
New York State Pavilion—Saturday & Sunday, October 17-18: 1:00 pm – 5:00 pm.

This year’s OHNY Weekend coincides with the 50th anniversary of the closing of the 1964-65 World’s Fair, which was held in Flushing Meadows Corona Park in Queens. Though many pavilions were demolished or moved after the fair ended, several were saved and have become emblems of the city’s largest and most diverse borough. Visit the former fairgrounds to explore Mid-Century Modernist works that will include Wallace K. Harrison’s New York Hall of Science, Philip Johnson’s New York State Pavilion (pictured), and tours of a dozen other landmarks with NYC Parks docents.
