The original main building of the Beverly Hills Hotel was designed by Pasadena architect Elmer Grey, in the Mediterranean Revival style. Built on a prominence above the main road below, it resembled a white colonial palatial mansion or mission, with verandas and arches fitted with wicker furniture, and at the time was set in the countryside. High above the main entrance are three domes, two flanking the center, which are smaller and lower in height, with flags hoisted on them. A trolley-stop pavilion was situated on the western side. The iconic signage and the addition were designed by architect Paul Williams.
