Kansas City, Mo ? A 19-story office building that once won national architectural acclaim has been listed as a federal historic landmark.

The designation could make the square, glass-covered BMA Tower in midtown Kansas City eligible for tax incentives to help pay for millions in needed renovations.

The BMA Tower, which opened in 1963, is an international-style building. The Seagram Building in New York is one of the most well-known examples of the style, which features modern materials, such as glass, concrete and steel.

The BMA Tower has been for sale since last winter.

The tower was designed by Skidmore Owings & Merrill of Chicago and New York. Its frame was built of white Georgian marble, which was replaced in 1987 when the slabs began to fall.

The building received the First Honor award from the American Institute of Architects in 1964. The Lambert-St. Louis International Airport terminal is the only other Missouri building to receive the honor.

New York’s Museum of Modern Art included the BMA Tower in an exhibit on 20th-century American architecture put together in 1965.

Approval was granted late last month to list the BMA Tower on the National Register of Historic Places. The listing qualifies it for federal and state tax credits on approved renovation work.

The tower needs an estimated $16.7 million in work to repair major systems.
