Stelz (German for stilt) allows urban gardening with style on minimal space. The system lifts the plantpots from Eternit, designed by Willy Guhl, to the desired level, like usual for stilts.
The soft wooden core breaks through the strong steel tube and gets gently wrapped by it. The assembly works simply and without tools. The components can simply be clamped by a wing nut on a meaningful hole grid. The system can be expanded as desired and can also be easily adapted to individual dimensions with drilling and sawing. A sustainable and ecological production of the components is easily possible in Switzerland.
