BEYOND THE GARDEN
Built for a Longer Game
Straightcurve is part of The Ignition Chamber, an Australian company that builds vertically integrated climate infrastructure companies. Each one funds what comes next.
Circular Design
Zero plastic packaging
Two years of R&D replaced every piece of foam and plastic with waterproof cardboard and compostable tape.
Carbon Capture
Essier bamboo decking
Bamboo boards that are 60% carbon negative, returned at end of life for permanent underground storage.
Climate Housing
Elysium Living
Homes designed to be carbon negative to build, energy positive to live in, and globally deployable.
Why a garden company builds houses
Straightcurve was the first company built inside The Ignition Chamber. The lessons from scaling it across seven countries are now being applied to carbon-negative housing.
Straightcurve started with a redesign of steel garden edging. No welding. No specialist tools. Professional results from a single modular system. But scaling globally meant confronting harder questions. Weathering steel corrodes over time. Packaging depends on plastic. Every product sold is ore pulled from the ground in a form that never comes back.
Two years and hundreds of thousands of dollars later: protective coatings that keep all steel intact for recycling. Cardboard waterproofed with organic oil instead of plastic film. A product genuinely designed for recovery and reuse.
The same stubbornness produced Essier, bamboo decking that is 60% carbon negative. And Elysium, housing designed to remove carbon from the atmosphere. Each company funds what comes next.
