A porch is a covered structure attached to the entrance of a building, typically a house. It serves as a transitional space between the outdoors and indoors, providing shelter from the elements. Porches can be open or screened and are often used for relaxation, socializing, or enjoying fresh air. Porches come in various styles and sizes, depending on architectural design and personal preference. They may feature seating, plants, or decorative elements. Common types include front porches, back porches, and verandas, each offering unique benefits and aesthetics to enhance a home's exterior.
