Choose Your Design

Every build starts here. All four designs remove invasive eucalyptus and return the land to fire-resilient habitat. Choose based on your site, your hands, and how deep you want to go. Start with the Gothic Tunnel Greenhouse — it’s the simplest design to build, gives you a tall productive growing space, and lets you learn the eucalyptus pole-bending techniques used in every subsequent design.

Gothic Tunnel Greenhouse

A 3m × 10m gothic-arch tunnel with a 6.5m pointed apex — tall enough for citrus, banana, and small fruit trees. Six pole pairs meet at a sharp gothic point. Two off-the-roll 8m × 10m plastic sheets cover the structure with a continuous ridge vent down the middle. The simplest design to learn pole bending and the fastest to a productive growing space.

Greenhouse BioDome

A 6m circular dome greenhouse — same arch frame as the Standard BioDome, stripped to poles, wattle rings, and greenhouse plastic. Two people, one weekend, under €300 — and it upgrades directly to a permanent Standard BioDome dwelling when you’re ready.

Standard BioDome

A wattle-and-cob dome built by two people with hand tools. Curved walls, a living roof, and 28m² of warm, breathable interior — rooted in a tradition older than concrete.

Earth Sheltered SolarPod

Cut 3 metres into a south-facing slope. Da Vinci bridge rafters span the opening without metal fasteners. Passive cooling in summer, thermal mass through winter — 35m² that barely exists above ground.
