To participate in the annual competition of experimental projects of novice architects PS1, a young American architect, William O’Brien, Jr. suggested the unusual “triangular” concept house. His Allandale House – a modern version of the forest cabin based on an extruded A-frame. The cabin consists of three conventional and visually identified asymmetric volumes. The skinny and highest part, which is located on the west side, contains an extensive library, wine cellar and a garage. Two floors of the widest part, which falls in the center of the house, contain bedrooms and bathrooms. The eastern part of the building consists of a living room, kitchen and dining room.
