The Problem

Workspaces are flexible.
Their materials are not.

Office interiors change every 7 years on average, but the materials used last 30. Every reconfiguration means new waste, new logistics, new cost. Conventional partition systems are not built for the circular economy.

Our Solution

Stand-alone partition systems, built to return.

We design and sell modular mycelium-based stand-alone partition systems for flexible workspaces. When a workspace evolves, they come back to us: remade, not replaced.

♻
Circular Take-Back
Return your stand-alone partition systems when layouts change. We remanufacture and deliver back at lower cost. Zero landfill.
🍃
Biobased Material
Grown from fungal mycelium and local agricultural waste. Near-zero embodied carbon, fully biodegradable.
▦
Flexible by Design
Modular, stand-alone systems that reconfigure with your space. No fixed installation, no waste.
✶
Biophilic Aesthetic
Natural texture and warmth that elevates workspace atmosphere and strengthens your sustainability story.
Technology

Grown, not manufactured.

Our stand-alone partition systems are produced by cultivating mycelium, fungal root networks, on locally sourced agricultural waste. The result is a rigid, lightweight, and fully circular material.

🍄
Mycelium Matrix
Fungal mycelium binds agricultural fibres into a rigid composite as it grows. No synthetic adhesives, no fossil inputs.
🌾
Agricultural Waste Substrate
Feedstock sourced from local Dutch farms: straw, husks, and offcuts that would otherwise go to waste. Near-zero cost, near-zero carbon.
🔬
Performance Testing
First-gen 120×60 cm prototype completed. Ongoing tests for acoustic performance, fire resistance, water resistance, and structural integrity.
Products

What we’re building.

Our stand-alone partition system is in active development. Here’s where we are today, and where we’re headed.
