Form derived through the subtraction of volumes that are generated by views, light, air, ground, and circulation creating spaces that are intrinsically related to the operations performed on it. These voids set up a series of moments that are programmed specifically to afford public private and circulatory needs geometric primitives subtracted from the whole can leave their own residue in the form liners that envelop material change. The liner takes shape as a perforated screen varying density on local programmatic needs.
