A front door is the main entrance to a building, typically a house or an apartment. 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 building's design. In addition to security, front doors can enhance the curb appeal of a property. Many homeowners choose decorative elements like doorknobs, knockers, and house numbers to personalize their entrance. A well-maintained front door can create a welcoming atmosphere for guests and reflect the homeowner's style.
