Open House New York and Wikimedia NYC invite you to submit your best OHNY Weekend photos to our photo competition on Wikimedia Commons!

More than 1,000 photos taken during OHNY Weekend are submitted to the photo competition each year. Submissions are judged in one of three categories – Interiors, Exteriors, and Details – for a chance to win prizes. All submitted photographs also become part of Wikimedia Commons, the online repository of free-use, public domain images that are used across Wikimedia—including as illustrations for Wikipedia articles. Nearly 200 photos from OHNY Weekend are already being used to illustrate articles across the world, from the entry on “rusty” in Polish, to “light fixture” in Estonian, to “nostalgia” in Bengali!

In addition, submissions to the 2017 competition will also be considered for publication in a forthcoming book of photographs, published by Open House New York in celebration of the 15th anniversary of OHNY Weekend! 

Submissions will be accepted starting on October 14 and through Sunday, October 22 at 11:59pm. 

Read on for the full competition details!

While the majority of sites open during OHNY Weekend are Open Access and can be visited free of charge and without reservations on a first-come-first-served basis on October 14 and 15, some sites and tours require Advance Reservations due to space or security restrictions. Information about all sites and tours can be viewed at starting on October 4. Advance Reservations begin on Thursday, October 5 at 11 am.

In 2016, more than 12,000 reservation slots went live on Reservation Day, and 10,000 were booked within the first hour. If you’re a seasoned OHNY Weekend participant, you know it’s an intense day for everyone regardless of how successful you might have been in getting the tours you wanted. What Adele and Beyonce are to concerts or Hamilton is to Broadway musicals, OHNY Weekend is to buildings, and Reservation Day generates a range of emotions that run from exhilaration to frustration. 

If this is your first Reservation Day, we recommend taking a few points into consideration as you get ready for the big day. Above all, keep in mind that tens of thousands of people compete for limited spots. In 2017 we had upwards of 37,000 users on our website on Reservation Day, who viewed more than 340,000 pages…in one day! While OHNY staff makes every effort to work with site hosts to facilitate as much access as possible, some sites have very limited capacity, and tours can be booked seconds after reservations open. If it seemed like all of the tours sold out immediately, it is because in large part they did. If there are 100 slots at a site and 2,000 people are trying to reserve tickets, it can literally come down to a difference of milliseconds!

Where to Go
OHNY uses Eventbrite to manage all reservations for OHNY Weekend. Each Advanced Reservation tour has its own web listing at and a corresponding reservation page on Eventbrite. Reservation links to Eventbrite will go live on each site’s webpage on at 11 AM EST on Thursday, October 5. A list of all Advance Reservation tours with links to each Eventbrite page will also be posted on at that time, as well as on OHNY’s Facebook page and the OHNY blog.

How it Works
There is a $5 fee, per guest, for each reservation, and you will be able to reserve up to two spots at a time. If you are reserving for more than two people on a tour, you will need to go through the reservation process multiple times. This is done to ensure that no one guest is able to book large numbers of spots on any one tour. Once you begin a reservation, Eventbrite gives you eight minutes to complete your reservation, so have your payment information ready before you begin. Note that Eventbrite only allows you to have one active registration at a time so you will not get an edge by trying to register for multiple tours at once. 

Speed it Up
You do not need an Eventbrite account to make reservations for OHNY Weekend tours, but having one can help speed up the reservation process, as Eventbrite will save your name, address, and credit card info (if you grant it permission to do so). This cuts down on the time each reservation will take to complete.

Know your Priorities
The more excited you are about a tour, the better the chances that lots of other people are excited about it, too. Try your top choice first, but also have a backup ready. Because it comes down to milliseconds, Reservation Day is a lot like a lottery – if you’re lucky, you’ll hit the reserve now button a millisecond faster than someone else. If not, there are more than 140 Open Access sites that don’t require reservations. 

Open What?
The majority of sites participating in OHNY Weekend can be visited on a first-come-first-served basis without reservations on October 14 and 15. These sites are Open Access because they don’t have the same space and security issues as Advance Reservation sites do. If you can’t get a reservation for a tour, there are still many beautiful, fascinating, and wonderful places to explore during OHNY Weekend. We’ve heard plenty of people say “all of the best sites require reservations,” but we can say that this is emphatically not true. All of our most visited sites, from the Brooklyn Army Terminal to New York City Hall, require no reservations at all!

The growth of Open House New York Weekend over the past decade and a half has roughly paralleled that of a city initiative that has had an extraordinary impact on the quality of civic architecture in New York: the Design + Construction Excellence program of the New York City Department of Design and Construction (DDC). DDC is the city agency responsible for building many of the municipal facilities that New Yorkers use every day: buildings and interiors such as libraries, museums, and senior centers, as well as courthouses, fire stations, and even roadways and sewers.

With the creation of the Design + Construction Excellence (DCE) program in 2004, the city reasserted its commitment to giving New Yorkers public buildings worthy of the greatest city in the world. Working with some of New York’s best architects and designers, DCE has invested in design to elevate not just how a building looks, but the durability of its materials, the way it functions, and most importantly, how it enriches the lives of the New Yorkers who use it. It is in part because of DCE that New York City is now considered among the leading centers of architecture in the world.

Working in partnership with DDC, Open House New York is proud to open a small selection of the hundreds of projects that have been built through DCE, as a way to recognize and celebrate the importance of the civic realm to shaping the day-to-day lives of all New Yorkers. Some Civic Excellence sites will have Open Access hours and may be visited free-of-charge on a drop-in basis; others require Advance Reservations. Full tour descriptions and information about how to visit these sites will be available on October 4.
