Once the initial meeting has been completed, a concept will be generated. This concept usually includes three drawings: floor plan(s), exterior elevations, and a site plan. This set of drawings is used as a general scope of what the final design will look like and the project as a whole will entail.
Usually, a takes a several iterations of refinement to come up with a design which is acceptable to all parties, including the owner, the architecture review board (if you belong to an association with CC&R’s), and the municipality in which it is located (city, county).
This phase typically incorporates other design professionals, such as geotechnical engineers, hydrologists, civil engineers, surveyors, etc.. Such design professionals are needed to determine site feasibility. If the site has any issues that would be prohibitive of building (i.e. seismic fault identification, water course issues, percolation studies, grading & slope issues, property line matters, easements, encroachments, etc.), it needs to be addressed prior to any further design work.
