The new owner of Manhattan’s Waldorf Astoria said it will work with New York City officials to maintain the hotel interior’s distinctive Art Deco details after preservationists raised concerns that a condominium conversion may threaten them.

Anbang Insurance Group Co., a Chinese insurance company that last year bought the hotel for $1.95 billion, disputed assertions by the New York Landmarks Conservancy preservation group that it had refused to support landmark protection for the hotel’s interiors during a meeting of representatives of both organizations.

“Anbang has never said it is opposed to landmark designation,” spokesman Jeremy Soffin said in an e-mail. “We are committed to working cooperatively and collaboratively with the Landmarks Preservation Commission to achieve an outcome that respects and r‎einvigorates the Waldorf Astoria for the next 100 years.” The commission is the city agency responsible for protecting architecturally, culturally and historically significant buildings.

Anbang become one of the world’s most prominent real estate buyers with its acquisition of the 1,413-room Waldorf Astoria, paying the highest price ever for a single existing hotel in the U.S. The Park Avenue property is scheduled to close in the spring for a multiyear retrofit that will probably see most of its rooms converted to luxury condos, according to a person with knowledge of the plans.

Conservationists’ Concerns

The plans sparked concern among the city’s preservationist groups. The Art Deco Society of New York posted a notice on its website headlined “Deco in Danger,” warning that the hotel “would be gutted and turned into condos.” The group invites readers to fill out a form to go directly to Meenakshi Srinivasan, chairwoman of the New York City Landmarks Commission, to demand that the panel quickly designate the areas for protection. The hotel’s exterior is already designated a landmark, while its interiors aren’t.

The Landmarks Conservancy and the Historic Districts Council also joined the fight. The conservancy wants to protect the hotel’s famed Peacock Alley, a Louis Rigal mosaic in the foyer, the grand ballroom where Guy Lombardo’s band used to play each New Year’s Eve and the 18th floor Starlight Roof where guests once danced under the stars.

The hotel’s interiors “are currently under review by the agency,” said Damaris Olivo, a spokeswoman for the commission. Because the exterior is landmarked, Anbang and its representatives are required to submit their plan to the commission because the alterations are expected to be significant and could affect the outside of the hotel. The city Department of Buildings would also have to sign off on any plan.

Commission Urged

The conservancy sent an e-mail earlier this month to its members urging them to demand the commission act to save the interiors. The group said in the e-mail that it met with three Anbang executives, and while “they appreciate the historic character of the building and they know how much the hotel means to New Yorkers,” they “oppose any interior landmark designation.”
