In Quoque, Long Island, N.Y., this shingle-style beach cottage is positioned at the edge of a high dune. The overscaled stoop leads up to an inviting porch and the main level. The attic is lit by a boldly arched window. The dining room has a view of the ocean. The living room, adjacent to the dining room, has plenty of seating. The house contains three small guest bedrooms. The master bedroom is located in the attic, its arched window giving the house a big scale. Photos of Quoque house by Peter AaronlEsto Photographics.
