Building projects require various types of drawings including location plans, site plans, floor plans, elevations, and sectional views. Location plans show the building site in relation to surrounding buildings and features. Site plans provide a larger view of the plot and include boundaries, building position, access paths, and drainage details. Floor plans display the internal room layout, dimensions, and plumbing and electrical components. Elevations present external views of the building style, proportions, and features. Sectional views cut through walls to illustrate construction materials and methods at a detailed scale.
