What are the basic four types of drawings included in an ordinary set of building plans?

The basic four types of drawings included in an ordinary set of building plans typically consist of plot plans, floor plans, elevation details, and structural drawings.

Plot plans provide a detailed layout of the building site, showing the arrangement of the building in relation to property boundaries, site access, and landscaping. Floor plans illustrate the arrangement of spaces within the building, including dimensions and the locations of doors and windows. Elevation details show the exterior views of the building, including heights and architectural features. Structural drawings communicate the framework and load-bearing elements of the building, which are essential for ensuring its stability and safety.

These drawings collectively give a comprehensive overview of both the design and the functional aspects of the building, serving as critical tools for surveyors, engineers, and the construction team. They are integral in the permitting process and guide the actual construction work.
