Once a final design is ready to be built, the architect and his or her draftsmen complete construction documents to guide the builders and craftsmen. This drawing was drafted by Charles Rennie Mackintosh for the remodeling of a farmhouse.

Mackintosh has employed line, colour and text to help the builders to understand additions and alterations to the original farmhouse. After this drawing was reviewed by the workmen, additional information was added with red ink. These changes make certain features clearer or change the design based on what existed in the field. Once an architect has completed the first set of plans of a building, complications in construction, cost considerations or errors in the planning will demand many more drawings and documents over the course of construction.
