A front door is the main entrance to a building, typically a house. It serves as a barrier between the outside environment and the interior space, providing security and privacy. Front doors can be made from various materials, including wood, fiberglass, and metal, and they often come in different styles and colors to match the home's design. In addition to their functional role, front doors can enhance a home's curb appeal. Many homeowners choose decorative elements like doorknobs, knockers, and house numbers to personalize their entrance. A well-chosen front door can create a welcoming atmosphere for guests and reflect the owner's taste.
