Allandale House is an A-frame(s) house designed by William O’Brien Jr. It’s a small vacation house with asymmetrical design. It links three horizontal extrusions of “leaning,” or asymmetrical A-frames. The skinny A-frame on the western side contains the library, wine cellar and garage. The wide A-frame in the center of the house is dedicated to two floors of bedrooms and bathrooms. The medium A-frame on the eastern side consists of living, kitchen and dining areas. The house is full of built-in storage. In the widest A-frame a second floor could be found. That was possible only there that’s why it end up in the middle of the whole house.
