A "front door" is the main entrance to a building, typically located at the front. It serves as a barrier between the outside and inside, providing security and privacy. Front doors can be made from various materials, including wood, metal, or fiberglass, and often feature locks for added safety. In addition to security, the front door contributes to the overall appearance of a home. It can be designed in various styles and colors, reflecting the personality of the occupants. Many front doors also include windows or decorative elements, enhancing the aesthetic appeal of the building while allowing natural light to enter.
