Attention architecture porn aficionados: Open House New York is back for their 7th annual weekend event, which will give you the key to places you normally wouldn't be allowed to enter. This will all go down on October 10th and 11th, with 350 tours, talks and programs in all five boroughs. Renee Schacht, executive director of OHNY, says "This year, we are thrilled to feature private residences, historic landmarks, architect and artist studios, and new sites that demonstrate sustainable design.”

Some of the highlights they've announced are the Apollo Theater; the Atlantic Avenue Tunnel; a contemporary live-work architectural studio in the Red Hook section of Brooklyn—a contemporary gut renovation of a historic 1899 carriage house; the award winning Slot House in Fort Greene. Some old favorites will return, as well, including: the Alice Austen House, Angels and Accordions at The Green-Wood Cemetery, the Brooklyn Navy Yard, Ellis Island's South Side and many, many more.

This year they'll also raffle off a behind-the-scenes-tour of the Woolworth Buildlling at their opening party that Friday (held at the The Visionaire, aka: the greenest residential development in the United States).
