Union Square's former Tammany Hall building is being redeveloped – the landmarked structure is getting a glass dome addition to its roof while the inside has been completely gutted. The building is famous for serving as the headquarters of Tammany Hall, the Democratic political machine that dominated New York City politics from the 1850s through the 1930s. Designed by BKSK Architects and developed by Newmark Knight Frank, the redevelopment entails gutting the building's interior, including a theater where New York politicians including Franklin D. Roosevelt and Al Smith once spoke. The design calls for four lower retail levels with three levels of office space above and in the dome.
