San Franciscans Sharon Stone and her husband Phil Bronstein are fighting a neighbor’s construction plans, which they say will block their view of the Golden Gate Bridge. The disagreement hints of an old publishing rivalry: Bronstein is executive editor of the San Francisco Examiner, while the neighbor, Candyce Martin, is a great-granddaughter of San Francisco Chronicle-founder Michael de Young. Martin is planning a 1,300-square-foot addition to her home in the posh Sea Cliff neighborhood. Through architect Michael Rex, Bronstein and Stone have asked the city’s Planning Commission either to reject Martin’s project or require that it be redesigned. The issue is to be heard May 6.
