Second, schematic design involves visually presenting multiple options to hone in on the right design and construction plans. Third, is design development, which includes creating a physical or computer model of the agreed on design and construction plan. Fourth, is construction development, which involves selecting the materials needed to fulfill the design, such as flooring, cabinetry, countertop materials, and more.
