Architectural models are physical or digital representations of buildings and structures, used to visualize and communicate design concepts. They help architects, clients, and stakeholders understand the scale, form, and spatial relationships of a project before construction begins. Models can range from simple sketches to detailed 3D printed versions. These models serve various purposes, including design development, presentation, and marketing. They can be made from materials like cardboard, wood, or plastic, and can also be created using software like AutoCAD or SketchUp. Architectural models play a crucial role in the planning and approval processes of construction projects.
