Robert J. Platt

Robert Platt was born on October 21, 1921. After earning his Bachelor’s degree from the University of Minnesota in 1946, Platt worked for Liebenberg & Kaplan in Minnesota in the early 1950s.

Arriving in San Diego a short time later, the young architect worked for Frank L. Hope. Among Hope’s projects Robert worked on between 1953-54 was Sharp Hospital. Robert Platt hung out his own shingle beginning in 1955 in various iterations.

The firm was handed over to his son, architect Lee Platt, in 1980. Platt was president of the San Diego chapter of the AIA in 1964, earning a place in the College of Fellows in 1970.

Robert Platt's archive is available HERE.

Platt's offices were located at 1870 Rosecrans, Point Loma (ca. 1957-60); 2638 Byron Street (AKA Shelter Island Drive), Shelter Island (ca. 1960-1970); and 1844 Third Avenue (ca. 1975-77).
