The interior defines the purpose of a building. The design must balance the functional needs and the aesthetic preferences inside of a structure. A commercial building is one used for some sort of business purpose, such as a store, office, warehouse, or restaurant. Just as there are many types of buildings, there are different types of interior design. Houses utilize one kind of design, while commercial structures have very different needs.
The main things about interiors are the use of physical space and aesthetics. If the design of a house is centered on livability, then the design of a commercial building is based on usability. Space needs to be usable for both employees and customers to maximize profits. Commercial interior design includes a broad spectrum of interior commercial spaces and environments, including offices, retail stores, restaurants, and other spaces where business is conducted.
