Periwinkle Street, Boca Raton, Florida. Boca Raton's unique and historic neighborhood of Old Floresta was originally established in the 1920's by visionary architect Addison Mizner. Poised on a choice corner lot, this gracious West Indies-inspired estate is served by a Chicago brick walkway and fountain courtyard in a tropical setting studded with a canopy of mature vegetation. The loggia with tongue-and-groove wood ceilings overlook the glistening pool encompassed a chiseled stone patio inviting outdoor entertaining or relaxing in complete private seclusion.
