Patios and porches are outdoor living spaces typically attached to a house or building. Patios are usually paved areas made of materials like concrete, brick, stone, or tiles and are used for dining, lounging, or entertaining outdoors. Porches are covered areas often with a roof and can be screened-in or open, providing a sheltered space for relaxation or socializing. Both are popular features for enhancing outdoor living and increasing the usability of outdoor areas.
