A Hobbit door, also known as a round-topped door, is an architectural feature that originated in J.R.R. Tolkien's "The Hobbit" and "The Lord of the Rings" novels. These doors have a distinctive rounded top and are often associated with cozy, rustic homes in fictional Middle-earth. The unique design adds charm and whimsy to any residence while also providing excellent insulation and energy efficiency.
