The Merchant’s House Museum, a 19th-century landmark and an East Village institution, is taking legal action that it hopes will curtail a hotel that’s due to rise next door. According to the Wall Street Journal, the museum has filed a petition with New York Supreme Court alleging that the Department of City Planning and the hotel’s developer, Kalodop II Park, have not adequately represented the danger posed to the historic structure by hotel construction.

“Given that the house is 186 years old, it’s fair to say that it’s extremely fragile,” Margaret Gardiner, the executive director of the Merchant’s House Museum, told the WSJ. “It’s not going to be able to survive construction next door, I guarantee you.”

The eight-story hotel has been in the works for several years, with the Landmarks Preservation Commission approving plans for the new construction all the way back in 2014. The lawsuit also alleges that the developers “submitted false information” to DCP, which is how it has received city approval thus far.

The hotel would rise 100 feet on a lot next door to the museum, replacing a one-story garage that’s used to house food carts. The developers are seeking a spot rezoning to build the structure that high, and it’s currently going through the city’s uniform land use review process. So far, the project has been rejected by Community Board 2, and the petition still needs to be heard by Manhattan Borough President Gale Brewer, the City Planning Commission, and the City Council.
