Eight Midtown office buildings and hotels are being considered for landmarking status.

“The owners have received a letter from city Landmarks stating that the buildings are being considered for landmark designation, and requesting a meeting with the owners,” spokeswoman Lisi de Bourbon said.

The landmarking efforts were prompted by the proposed East Midtown Rezoning that will affect the core of Midtown around Grand Central Terminal and as far north as 57th Street. Outdated properties in the up-zoning district could be torn down and enlarged beyond their current square footage.

De Bourbon said the office buildings include: JPMorgan Chase’s 1958 1.5 million-square-foot tower at 270 Park Ave.; 125 Park Ave. developed on E. 42nd Street in 1923; the 1927-era Graybar Building at 420 Lexington; the white 445 Park Ave. at E. 57th Street built in 1947; and the green glass 151,000-square-foot former Girl Scouts building at 830 Third Ave. developed in 1958.

In addition, three hotels along Lexington are under consideration: the Radisson Lexington at 509; the New York Marriott East Side at No. 525 that was once known as The Shelton; and the Benjamin at No. 557.

Both the Graybar building and 125 Park are owned by SL Green Realty Corp., whose spokesman declined comment. Other owners did not respond to requests for comment.
