The following are descriptions of who's house:
"It was a factual imitation of some Hotel de Ville in Normandy, with a tower on one side, spanking new under a thin beard of raw ivy, and a marble swimming pool, and more than forty acres of lawn" (11)
"....a cheerful red-and-white Georgian Colonial mansion, overlooking the bay" (12)
