Treehouses
Transcript:
The temporary buildings or structures constructed on mature trees, above ground level, are known as tree houses. These small structures are usually built for leisure or as a retreat. They can also provide safety from wild animals if they are built in a forest. They are considered to be eco-friendly houses because the trees do not need to be cut down for them to work as habitats.
