Energy
It pays you back
Solar generation and battery storage sized to exceed what the home consumes — independence from a grid that only gets more expensive.
More than 100% passive
The house that makes more energy than it lives on.
Walls of compressed straw. A roof of sun. Storage that carries you through the night. Engineered into a home that produces a surplus of energy every year — and sends the utility bill to zero.
Inside the wall
One structural base, finished many ways.
The panel isn't a single wall — it's a system, closed and finished to suit each site: ventilated cladding and wood-fibre board outside, a compressed-straw core in a twin timber frame, an airtight membrane and clay or lime plaster within.

Why straw, and why now
A proven material, engineered into a modern home.
Resilience
Built to hold
Rigid plaster skins over a resilient straw core behave like a structural insulated panel — a wide, load-spreading wall that absorbs seismic forces.
Safety
Fire-resistant
Compressed straw is too dense to feed a fire; rendered assemblies are certified for 120+ minutes (industry benchmark).
Health
Breathable & quiet
Vapour-open walls regulate humidity naturally, with no off-gassing — and 40–65 dB of sound reduction (industry range).
Speed
Prefabricated
Made-to-order panels arrive ready to assemble — fast, repeatable, weather-independent construction.
Carbon
A wall that stores CO₂
Straw is a renewable by-product; each m² of panel locks away roughly 115 kg of CO₂ instead of emitting it.
"They told her a straw house would burn. It's certified to hold back fire for two hours."
Answering the honest questions
Fire, pests, moisture, resale, earthquakes — every worry has a clear, evidence-based answer. We'd rather show you the proof than sell you a feeling.
