Home blueprints are drawn to scale so that if any specific dimension needed is missing, the contractor can scale the drawing to determine the right size. The main floor plans are generally drawn to ¼" scale which means that every ¼" on the plan equals 1' in real length. Other details like framing layouts or built-in details may be drawn at another scale like 1/8" or even ¾". The scale of each house blueprint is usually called out beneath the drawing or somewhere on the page, usually next to the title.
Elevations are a non-perspective view of the home. These are drawn to scale so that measurements can be taken for any aspect necessary. House Blueprints include front, rear and both side elevations. The elevations specify ridge heights, the positioning of the final grade of the lot, exterior finishes, roof angles and other aspects that are necessary to give the house its exterior architectural style.
Floor plan views or overhead views of the structure don't always provide enough information on how the house is to be built. Often times cross section or details will explain certain special conditions more appropriately. A cross section is basically a view of the house if it were sliced down the center. This allows you to view the home from the side and understand a little better the relativity of varying floor heights, rafter lengths, and other structural elements.
