We're building the open operating system for circular construction — and proving it with every building we own.
Once a bank can assess a component's residual value as reliably as it assesses land, circular construction becomes financeable. We're building the open stack and the bankable standard for that — and our own buildings, where we prove it ourselves first.
A building doesn’t lose its economic value all at once — it loses it component by component, every time something is installed in a way that can only be demolished later, never released again. At the end of a building’s life there’s usually a demolition crew, not value. Deconstruction costs money instead of returning it.
That can be reversed — not through persuasion, but by making material bankable. Once a component’s residual value is as reliably assessable as that of a plot of land, circular construction becomes the default instead of the exception. Components become assets with documented value, not debris with disposal costs.
That’s why we don’t just build the open stack — we build and hold our own buildings too: proof before claims. What holds up there becomes a stack module — what doesn’t gets cut from the model before anyone else adopts it.
Success for us doesn't mean being right — it means others adopting our model.
How we calculate viability
Circular construction has to hold up economically, not just ecologically. Whether it does isn’t decided by any single project, but by whether four theses hold at the same time — and reinforce each other rather than just adding up. We deliberately show what isn’t proven yet, too: that’s what separates a business case from a pitch.
A simplified example, for illustration only
Three advantages can already be quantified today — some independent of bank or buyer, some even when a buyer doesn’t reward the material value at exit at all (acid test, thesis 4):
up to +2 pp
up to +1 pp
up to -25%
