The architectural design process involves five main steps. First, pre-design refers to the ideation and planning phase. It involves working with you (the client) to understand needs and budget. 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. The final stage is construction development.
An architectural designer will guide you through each step in the design and construction process. You'll benefit from the architect's connections to contractors and knowledge of the permitting process in your area.
