Architectural models – materials
Rough study models can be made quickly using cardboard, wooden blocks, polystyrene, foam, foam boards and other materials. Such models are an efficient design tool for three-dimensional understanding of a structure, space or form, used by architects, interior designers and exhibit designers.
Common materials used for centuries in architectural model building were card stock, balsa wood, basswood and other woods. Modern professional architectural model builders are taking advantage of twenty-first century materials, such as Taskboard (a flexible and lightweight wood/fiber board), plastics, wooden and wooden-plastic composites, foams, foam board and urethane compounds.
A number of companies produce ready-made pieces for structural components (e.g. girders, beams), siding, furniture, figures (people), vehicles, trees, bushes and other features which are found in the models. Features such as vehicles, people figurines, trees, street lights and others are called “scenery elements” and serve not only to beautify the model,
