LOS ANGELES—New York gallery L&M Arts is set to open a Los Angeles branch on Venice Boulevard in about a year. Designed by architect Kulapat Yantrasat of the wHY Architecture firm, the gallery is renovating an existing building and adding a new two-floor structure. The West Coast project will be overseen by dealer Sarah Watson, who most recently worked for the Gagosian Gallery in Los Angeles. Plans for the new space include a broad-based program of both historical and contemporary art shows.
