Interior architecture drawings are used to communicate design intent and provide technical instructions for construction. There are several types of drawings used in the design and construction process. Conceptual drawings like perspectives are used early on to convey the design concept to clients. General arrangement drawings show the layout of furniture and fittings. Detail drawings include plans, sections and elevations used for design, cost estimation, and construction, providing dimensions and materials. These drawings are used by various parties like consultants, contractors, and quantity surveyors throughout the design and building process.
