Definition & Meaning of "tree house"

What is a "tree house"?

A tree house is a small structure built in the branches of a tree, often used as a play area, a retreat, or even a living space. These houses are usually elevated off the ground and are supported by one or more trees. Tree houses can range from simple, small platforms to more elaborate buildings with walls, windows, and roofs. They are popular for children to play in, but some adults also use them as peaceful escapes or unique homes. Tree houses are often designed to blend in with nature and offer a close connection to the outdoors.
