Ladera Heights originated in the late 1940s with the development of "Old Ladera". In the 1960s, custom homes were built in "New Ladera". Prominent architect builders included Valentine and Gallant. Robert Earl, who designed many of the Valentine homes, went on to build large multimillion-dollar estates throughout Southern California and in other countries. Neighboring Fox Hills contained a golf course with rolling hills that backed up to Wooster Avenue. Valentine built Robert Earl designed homes on Wooster overlooking the Fox Hills golf course. Years later, Donald Trump asked Earl to design estate homes with panoramic views of his Palos Verdes golf course.
