The timeless neighborhood of Pemberton Heights, is parked on a plateau above a steep ravine carved by Shoal Creek. These tony Texas neighborhoods, some with older pedigrees, rose to prominence with the first wave of oil money in the 1920s. They encompass mansions in manorial styles but also blocks of more modest, if still minutely manicured residences. In Austin, instead of oil barons, the upwardly mobile homeowners tended to be judges, professors or retail leaders. Pemberton and its southern neighbor, Old Enfield, were partitioned from the 19th-century plantation of Gov. Elisha Pease, whose pristine Greek Revival manse lies to the south of Windsor Road, which separates these “platinum” districts.
