You’ll Strap This Spiral Staircase Onto Any Tree Without Tools

Designers Thor te Kulve and Robert McIntyre have devised a clever system that allows you to build a spiral staircase within the trunk area of a tree without actually hurting it and without needing tools.

Their particular innovative staircase consists of birch steps that retain the tree trunk area with straps and grip its part with thick neoprene pads. Attaching a few these tips, with an accompanying handrail, creates a spiral staircase.

“We been employed by using the arboriculturalists at Hampstead Heath to ensure we’re not harming the tree,” McIntyre informed Dezeen. Trees can certainly still be damaged by girdling after even after sustained friction, so we believe these steps tend to be a temporary setup. According to the developers, a 7m staircase would simply take 2 people 3 hours to create but only 30min. to take apart.
