Interior renovation refers to the process of making significant changes or updates to the interior of a building or structure, typically a residential home or commercial building. This can involve remodeling, redecorating, or refurbishing the space to improve its functionality, aesthetics, and overall value.

Interior renovation projects can range from small-scale updates such as repainting walls and changing fixtures, to large-scale renovations that involve structural changes, such as removing walls or adding new rooms.

Common interior renovation projects include updating kitchens and bathrooms, adding or removing walls to create open-concept living spaces, replacing flooring or carpeting, upgrading lighting and electrical systems, installing new cabinetry or countertops, and adding new paint or wallpaper.
