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.[4] Stilts are typically anchored into the ground with concrete although new designs, such as the “Diamond Pier”, accelerates installation time and they are less invasive for the root system.[5] Stilts are considered the easiest method of supporting larger tree houses, and can also increase structural support and safety.
