Summer House Rules-East Hampton, New York

A Miami couple who traded palm trees for hydrangeas and bought an East Hampton home for long summers with their newborn baby. They arrive in June with the nanny, stay through Labor Day, host family for weekends, invite friends over without counting how many are coming, and believe a quiet afternoon by the pool should be able to turn into dinner, music, and dancing without anyone changing clothes. They want a house that feels sophisticated but never precious—beautiful enough for cocktails at sunset, relaxed enough for sandy feet and baby bottles, and designed for the kind of summers everyone wishes would last a little longer.
