2D planning refers to the process of creating two-dimensional representations or drawings that depict the layout, dimensions, and spatial arrangement of a building or space. These plans are typically used by architects, designers, and builders as a blueprint for construction or renovation projects.

Floor Plan: A floor plan is a top-down view of a building or space, showing the arrangement and dimensions of rooms, walls, doors, windows, and other features. It provides a clear understanding of the overall layout and flow of the space.

Site Plan: A site plan illustrates the entire property or site where a building is located. It shows the building's position, as well as other structures, parking areas, landscaping elements, and property boundaries. It may also include information about utilities, drainage systems, and access points.
