An internal fit-out refers to the process of furnishing and outfitting the interior of a building or space. This typically includes installing fixtures, fittings, and finishes such as flooring, walls, ceilings, lighting, cabinetry, and other interior elements to make the space functional, aesthetically pleasing, and suitable for its intended use. Internal fit-outs are essential for both residential and commercial properties to create comfortable and attractive living or working environments. They can range from simple upgrades or renovations to complete interior design projects, depending on the scope and requirements of the space.
