Schematic Design is the process that determines the scope, scale and relationship of the program pieces. The primary objective in Schematic Design is to develop a design with a clear understanding of the Owner's scope, budget, and schedule. The product of Schematic Design always includes a set of plans, exterior elevations, and one or more cross sections. The Schematic Design drawings may be used for Site Approval processes, or for a preliminary cost estimate from a contractor. Schematic Design drawings for a home in Hillsboro are shown below.
