Check
out this awesome system which enables anyone to create a temporary
spiral staircase up a tree, without causing any harm to the tree at all.
What’s amazing, is that no tools are needed to fit the staircase!
Designed by Robert McIntyre and Thor te Kulve, the birch staircase steps
are strapped to the tree and grip on through the use of neoprene
padding.
The
pair have worked closely with arboriculturalists to ensure their
invention is as kind to trees as possible. It has been found that the
staircases can only be fitted for a certain length of time before they
begin to harm a tree, therefore prolonged use is not advised. However
for a party or a family day, the staircase would be awesome and it only
takes a few hours to build and 30 minutes to disassemble too!
