Clara Gromaches

Architect, designing systems and pilots for housing and land commons.

Drawing on years of co-operative incubation, place-based policy, bio-architecture practice and edge technologies.

Expertise

Regenerative architecture

A contemporary vernacular

Bio-architecture: vernacular construction reinterpreted in a contemporary architectural language, with native materials of proven durability, allowed to age with dignity.

Housing commons

Viability and policy advisory

Project viability research, community incubation and policy work for social housing co-ops, alongside rural municipalities, foundations and tenants’ organisations in Catalonia.

Edge technologies

Blockchain and AI

Deep, hands-on work in blockchain and AI: a blockchain-native startup at dOrg from 2021 to 2026, community housing DAO prototypes, and now AI-native practice at Komma, building toward an AI-operated business and coordination.

System design

Where the practice converges

Designing the legal, social, economic and technical mechanisms that advance housing and land commons, and running the pilots that demonstrate them. Through Komma, registered in Germany and Liechtenstein.
