Housing Works is a charitable organization helping those who are homeless or have AIDS. Part of their charity is their thrift shops. The bag that was selected was a small, circular, red bag that was completely different from the inside than it was out. The concept developed through the bag analysis was the idea of an interior within an interior. Because of the different atmospheres of the exterior and interior of the bag, the same is applied with the space. The two different spaces are defined in two ways: brightness and darkness between shopping areas and purchasing areas and day versus night.
