About Okto.green
A building system.
Not a developer.
Okto.green is a European building platform for energy positive homes. We standardise the technical core — the building system, the supply chain, the certification process — and deploy it through a network of regional partners across Belgium and beyond.
What we do
The system is the product.
Okto.green does not sell houses. We build and govern a standardised construction system that regional partners use to develop energy positive homes in their area. Every house in the Okto.green network is built from the same technical core — achieving E −9 on every project, documented and independently certified.
The system is replicable. A regional partner in West Flanders builds the same way — with the same energy result — as a partner in Ghent or Antwerp. That is the point. Standardisation is not a limitation. It is the guarantee.
The platform ecosystem
Three brands. One system.
Okto.green operates within an ecosystem of interconnected platforms — each with a specific role in the construction and delivery process.
Where we are
Belgium first.
Europe next.
Okto.green is currently active in West Flanders with three regional partners and four projects in permit or subdivision track. The system is designed from day one for cross-border replication — same technical core, adapted to local building regulations.
New regional partners are being selectively onboarded for 2026–2027 — in Belgium and in neighbouring regions.
Building in the open
See it happen. Follow the build.
Our homes are built by a small core team and a strong network of craftsmen and partners. We share every step on site.
