Commercial fit out refers to the process of making interior spaces in commercial buildings ready for occupation. This includes designing and constructing elements such as walls, flooring, lighting, and furniture to create a functional and aesthetically pleasing environment. The goal is to tailor the space to meet the specific needs of businesses, whether they are offices, retail stores, or restaurants. The fit out process can be categorized into three types: shell and core, category A, and category B. Shell and core involves basic structural work, while category A includes essential services like heating and lighting. Category B focuses on the final touches, such as furnishings and decor, to complete the space.
