Empire Stores (Jake Dobkin/Gothamist)

Open House New York (OHNY) returns this October 11th and 12th, and this year some new spaces will be joining the 200 others, give or take, already on the docket. Many of the doors being open are not generally open to the public, and those tend to sell out fast. (Reservations can be made two weeks prior to the event.) From the announcement this week, here's what's new:

"New additions to this year’s OHNY Weekend include: the 425-square-foot Manhattan Micro-Loft atop a brownstone on the Upper West Side, containing four distinct “living platforms,” (Specht Harpman Architects); Weylin B. Seymour’s, an elegant new event space in the meticulously restored Williamsburgh Savings Bank building at the foot of the Williamsburg Bridge, with its soaring rotundas and original 1875 murals saved from ruin (George B. Post, Peter B. Wight); the collaborative working environment of the Barbarian Group’s office in Chelsea, featuring the much talked about undulating, endless, “superdesk” that seats their entire staff (Clive Wilkinson Architects); Empire Stores, a set of abandoned post-Civil War warehouses on the DUMBO waterfront, on the boards to be adaptively reused for offices and retail (Studio V); Kickstarter’s new headquarters in Greenpoint, in the remnants of the historic Eberhard Faber Pencil Factory (Ole Sondresen Architect); and the United Nations, which will have just completed a seven-year, $ 2 billion renovation of its campus along the East River."

More sites will be added leading up to the big weekend, and this year they're also hosting a Factory Friday, which will open doors to manufacturers of everything from bicycles to silk flowers.
