A treehouse is a small structure built in the branches of a tree, often used as a play area or a cozy retreat. These houses can vary in size and design, ranging from simple platforms to elaborate multi-room constructions. They are typically made from wood and can be found in backyards, forests, or parks. Treehouses provide a unique way to connect with nature, allowing people to enjoy the outdoors from an elevated perspective. They can be equipped with amenities like furniture, electricity, and even water access, making them suitable for both children and adults seeking adventure or relaxation in the trees.
