Tree house
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. People occasionally connect ladders or staircases to get up to the platforms.

In modern societies
Trees have historically been integrated into the construction of buildings, for example the walls of a chapel, to provide support to a structure built around them. Chêne chapelle is an example of this practice.[5] Modern tree houses are usually built as play areas for children or for leisure purposes, but may also be used as accommodation in hotels or residential applications. In this case, the main part of the structure is built with more typical construction materials. The use of tree houses in this manner is part of a movement towards the practice of "living architecture".[5]
Tree houses may be considered as an option for building eco-friendly houses in forested areas, because unlike more typical forms of housing, they do not require the clearing of trees.
Support methods and technology
There are numerous techniques to fasten the structure to the tree which seek to minimize tree damage.[6]
The construction of modern tree houses usually starts with the creation of a rigid platform, on which the house will be placed; the platform will lean (possibly on the corners) on the branches.[7] In case there are not enough suitable supports, the methods to support the platform are:
- Struts and stilts
Struts and stilts are used for relieving weights on a lower elevation or straight to the ground; tree houses supported by stilts weigh much less on the tree and help to prevent stress, potential strain, and injury caused by puncture holes.[8] Stilts are typically anchored into the ground with concrete, although new designs such as the "Diamond Pier" speeds installation and are less invasive for the root system.[9] Stilts are considered the easiest method[by whom?] of supporting larger tree houses and can also increase structural support and safety.
- Stay rods
Stay rods are used for relieving weights on a higher elevation. These systems are particularly useful to control movements caused by wind or tree growth. However, they are used less often due to the natural limits of the system. Higher elevation and more branches tailing off decreases capacity and increases wind sensitivity.[10] Building materials for hanging include ropes, wire cables, tension fasteners, and springs.
- Friction and tension fasteners
Friction and tension fasteners are the most common noninvasive methods of securing tree houses. They do not use
- Invasive methods
Invasive methods are all methods that use nails, screws, bolts, kingpins, etc. Because these methods require punctures in the tree, they must be planned properly in order to minimize stress.[11] Not all species of plants suffer from puncture in the same way, depending partly on whether the sap conduits run in the pith or in the bark. Nails are generally not recommended.[12] A special kind of bolt developed in the 1990s called a treehouse attachment bolt can support greater weights than earlier methods.[13][14][15]
Popularity
Since the mid-1990s, recreational tree houses have enjoyed a rise in popularity in countries such as the United States and parts of Europe.
Increased popularity has, in turn, given rise to demand for businesses covering all building and design work for clients. There are over 30 businesses in Europe and the US[18] specializing in the construction of tree houses of various degrees of permanence and sophistication, from children's play structures to fully functioning homes.
Popularity of tree house hotels is equally growing due to the popularity in the glamping and unique accommodation industries with a number of booking websites offering accommodation in tree houses.[19]
Building regulations
Many areas of the world have no specific planning laws for tree houses, so the legal issues can be confusing to both the builder and the local planning departments. Treehouses can be exempt, partially regulated or fully regulated - depending on the locale.[citation needed]
In some cases, tree houses are exempted from standard building regulations, as they are considered outside of the regulations specification. An exemption may be given to a builder if the tree house is in a remote or non-urban location. Alternatively, a tree house may be included in the same category as structures such as garden sheds, sometimes called a "temporary structure". There may be restrictions on height, distance from boundary and privacy for nearby properties. There are various grey areas in these laws, as they were not specifically designed for tree-borne structures. A very small number of planning departments have specific regulations for tree houses, which set out clearly what may be built and where. For safety during the tree house construction, it is usually best to do as much work as possible on the ground, taking long-term viability into consideration.[19]
