GreenStak is the invention of Philipp Jutzi — maker and a long-view thinker: someone who takes the long view, where food, energy, materials and space are all part of the same story of where we're heading.
GreenStak started with one purpose: a tool to grow healthy food, simply, anywhere — indoor or outdoor.
But the box is multi-use by design. Growing is where it began; storage, racking, organising and display all fit the same modular system. It stacks cleanly up to five high and is built to be carried and handled by one person.
The material isn't the point — the design is. Plywood is the version you see here, chosen for organic reasons. The same system can be built from any material that's flexible, stable, and fit for purpose.
Refined hands-on over years: the rack-up geometry and the two sizes (700er and 350er) were all worked out prototype after prototype.
HB 1.0 (2004) — the original plywood box. Tool-free and stackable, used outdoors for microgreens, herbs and wheatgrass.
HB 2.0 (2020) — fully redesigned: CNC-optimised, refined joinery, cut from a standard 4 × 8 ft sheet with minimal waste. Twenty years of iteration into a market-ready system, with complete design files, packaging and installation guides ready for production.
