The first precedent is called a redneck blind. This demonstration of a box blind would set the perfect precedent of a safe space where a person/people can get away from their environment for a period of time. It's roughly 10-12 ft off the ground but it encorporates just enough space to get away. In the box blind, outside viewers can't see the person/people within the blind unless the person/people inside choose for them to see. Meanwhile the person inside the blind can see everyone in the outside world. This truly allows for the feeling of getting away without truly getting away. It's built out of aluminum and plastic so it is very stable and not very difficult to assemble.

The second precedent is a picture of a family tradition double tripod. Although this is commonly used for hunting or observing it can be used very similar in the way to be in the environment of school without having to be asserted into the environment. Although this model portrays an open face/skin so people can still see the people within. So it allows enough space for multiple people, while being approximately 12-14 ft in the air. This sets the stage for an opportunity to be one with your environment while still being instilled in it. It is built out of iron cast metal and aluminum so it would be more difficult to assemble due to welding but not impossible.
