A tree house is a small structure built in the branches of a tree, often used as a play area for children or a cozy retreat for adults. These houses can vary in size and design, ranging from simple platforms to elaborate multi-room constructions. They are typically made from wood and are designed to blend in with the natural surroundings. Tree houses can provide a unique perspective of the outdoors, allowing occupants to enjoy nature from above. They are often equipped with safety features like railings and sturdy ladders. Many people build tree houses as a fun project, fostering creativity and a connection to nature.
