OHNY was started by Scott Lauer in 2001, who was inspired by his experiences volunteering with Open House London. The first OHNY was attended by about 45,000 people and it has grown exponentially every year since, adding new places and programs each year. Now more than 200,000 guests visit almost 200 of the city’s best places.

Several new additions this year focus on sustainability and green design. The 6,000 square foot Eagle Street Rooftop Farm, Loadingdock5’s Williamsburg Passive House, and the new LEED Gold Myrtle Hall at Pratt will all be open to the public. There are also several locations dedicated to kids’ activities, and the Center for Architecture will once again serve as the OHNY welcome center.
