The term "exterior" refers to the outer surface or appearance of an object, building, or space. It encompasses everything that is visible from the outside, including materials, colors, and design elements. For example, the exterior of a house may include its walls, roof, windows, and doors, all contributing to its overall aesthetic. In architecture, the exterior is crucial for both functionality and visual appeal. It protects the interior from weather elements while also providing a first impression. Landscaping, lighting, and outdoor features can enhance the exterior of a property, making it more inviting and attractive.
