Bon Appetit was acquired from Knapp Communications last year.

Condé Nast Publications, the current owners, purchased Knapp Communications in 1993.

Knapp Communications is going to publish another piggyback publication for its popular, upscale Architectural Digest magazine.

"It was a purely personal decision," Charles Perkins, a spokesman for Knapp Communications, said.

Built in 1972, the 22-story, 400,000-square-foot building is 45 percent occupied, and tenants include New York Life and Knapp Communications.

He began his career at Bon Appetit in San Francisco as managing editor in 1980, when the magazine was owned by Knapp Communications.

Knapp Communications is for sale.

Last year, the company acquired Architectural Digest and Bon Appetit from Knapp Communications.

Hachette will acquire Home, a consumer magazine about renovation and interior design, from Knapp Communications.

Even though both magazines have suffered declines in advertising, particularly in the last two years, industry analysts expect Knapp Communications will receive numerous offers.
