To remodel means to change and improve the structure or appearance of a building or room. When a family remodels their kitchen, they might tear out old cabinets, install new countertops, add better lighting, or knock down a wall to make the space bigger and more useful. Remodeling involves actual construction work that changes how the space is built and arranged, like replacing fixtures, moving walls, or reconfiguring the layout.

Homeowners often remodel bathrooms to add modern fixtures or create more storage. A school might remodel its library to include computer stations and comfortable reading areas. The word suggests serious construction work: there might be hammering, sawing, and dust everywhere before the improved space emerges.

You can also use remodel more broadly. A writer might remodel a story by restructuring whole chapters rather than just fixing typos. A city could remodel its downtown area by rebuilding streets and adding parks. The key idea is transformation: taking something that exists and reshaping it into something better, more functional, or more attractive than it was before.
