A tree house, tree fort or treeshed is a platform or building constructed around, next to or among the trunk or branches of one or more mature trees while above ground level. Tree houses can be used for recreation, work space, habitation, a hangout space and observation. It’s likely that living trunks and branches get skilfully integrated into the construction of a treehouse like this. Such treehouses can be multi-storey as well. There can be multiple rooms or cabins perched on different branches at various heights, connected through ladders or unstable stairways. I and some of my neighborhood friends decided to build a tree house. It came into creation in the beginning of the summer. It was built on avocado tree situated at the corner of our backyard. I would like my treehouse to be two-storied. first of all, we would be able to connect with nature. nowadays people are always on phone so this could be an escape route and be one with nature. Tree houses can be build at a cheap prices and it can be made moveable and customizable. Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark. In one year an acre of mature trees can provide enough oxygen for 18 people. A tree consists of a set of nodes and a set of edges that connect pairs of nodes. A tree has the following properties: One node of the tree is designated as the root node. Every node n, except the root node, is connected by an edge from exactly one other node p, where p is the parent of n. If you build a treehouse, the calming effect of being surrounded by that many green leaves can reduce anxiety, stress, and other mental health problems.
