Lever House

Why it's listed
Lever House is a twenty-four-story tower at 390 Park Avenue in midtown Manhattan, built in 1950-52 for Lever Brothers Company. A 53-foot-wide glass and steel slab rises above a two-story base that appears to hover over an open, colonnaded ground floor and courtyard. Stainless-steel mullions hold green-tinted glass panels and blue-green spandrels, and only the western service core is solid masonry. Skidmore, Owings & Merrill designed it, with Gordon Bunshaft as partner in charge. The building matters as an early corporate example of the International Style in postwar America. It was also among the first to use a New York zoning provision permitting a tower without setbacks if it covered only a quarter of its lot, and its open courtyard became a common feature of office buildings. Its construction started the shift of Park Avenue north of Grand Central from apartment houses to glass office towers. Historians widely treat it as a milestone of American architecture.
Significance in brief: The nomination argues it was one of the first corporate expressions of the International Style in postwar America and an outstanding work of Skidmore, Owings & Merrill. It was also among the first buildings to use a zoning provision allowing an unbroken slab with no setbacks and an open ground-level courtyard, and it began Park Avenue's change from residential to corporate use.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
