A trapdoor is a concealed door or opening in a floor, ceiling, or wall that can be opened to provide access to an area below or above. Often used in basements, attics, or storage spaces, trapdoors can be made from various materials, including wood or metal. They are typically hinged and can be secured with a latch or lock to prevent unauthorized access. Trapdoors are useful for maximizing space, allowing for hidden storage, or providing access to utilities, such as plumbing or electrical systems. In addition to their practical uses, trapdoors can add an element of intrigue or surprise to a room's design.
