Interior Designing

 Interior designers have interesting jobs because they alternate the space in which people live in. They get to create new interiors to homes and event places to change them into a space pleasing to the eye. For my personal project, i want to study the work of interior designers and what goes into the job. my question is what materials are needed to make a model of a house with interior design elements? I want to find out this information while doing my personal project and i plan to apply this information into building a model of my ideas.
