Partner network

Built in Belgium.
Scaling across Europe.

Okto.green operates through a network of regional partners — local developers who carry the Okto.green Building System into their area. We started in Belgium. We are building the network to scale the system across Europe, one regional partner at a time.

One building system.
Deployed by local partners.

The Okto.green Building System is designed from day one for cross-border replication. The technical core — the energy standard, the build protocol, the certification process — is the same in every country. What changes is the regional partner: a local developer who knows the land, the market and the planning rules.

We are currently active in West Flanders with three partners. In 2026–2027 we are selectively onboarding partners in new Belgian regions and beginning our first cross-border expansions.
