Interior renovation involves updating or improving the inside of a building, such as a home or office. This process can include changes to walls, floors, ceilings, and fixtures to enhance aesthetics, functionality, or energy efficiency. Common tasks include painting, installing new flooring, and upgrading lighting. Homeowners often choose interior renovation to increase property value or create a more comfortable living space. Professionals like interior designers and contractors may be hired to ensure the project meets safety standards and design goals. Renovations can vary in scale, from minor updates to complete overhauls of a room or entire property.
