If there are no drawings of existing buildings, these will need to be developed at additional cost. The architect will also need to consult with the City with respect to the building and zoning codes, as they apply. Every city is different. Every project has its own issues. The architect prepares a series of rough sketches, known as schematic design, which show the general arrangement of rooms and of the site.
Some architects also prepare models to help visualize the project.
The homeowner approves these sketches before proceeding to the next phase. This is where the budget is developed further, and the project scope is adjusted to meet the budget. The architect prepares more detailed drawings to illustrate other aspects of the proposed design. Floor plans show all the rooms in correct size and shape. Outline specifications are prepared, listing the major materials and room finishes.
