Shear House, a single family house in Korea, seeks how a simple treatment in pitched roof typology improves environmental qualities and influences to program organization. The volume of gable on the West end changes its placement along with body of house. It projects out toward South at the East end, while maintaining its triangular shape. The sheared volume is continuously pulled out towards South responding to sun orientation. It creates a deep eave in South and a terrace in North. The eave blocks direct sunlight in summer and allow natural lighting in winter. Openings at terrace in second level increase natural ventilation throughout the whole house. In addition double skin-facade controls heat and humidity thus the house reduces 20% of heat gain and loss in summer and winter. The house has two different ends, a typical gable end, and a sliced & shifted one in a monolithic structure and material. Shear House adds a new scene on the existing landscape. At the entrance of the town people face a typical gable wall. As they walk to the house entrance, they slowly recognize changes of eave and shadow and finally realize the sheared face at the entrance of the house.
