About

Thommesen Architecture designs industrial production facilities - primarily within seafood processing, aquaculture, dairy and food production. The practice has roots back to 1964 and operates from Trondheim, Norway under the leadership of Øystein Thommesen.

We are not a general-purpose architecture firm. Our entire practice is built around understanding how industrial production works and designing buildings that serve it.

Scope

Full project cycle from feasibility studies and regulatory approvals through detailed design to construction documentation. We also work with optimisation of existing facilities - capacity analysis, bottleneck identification, workflow reorganisation and staged expansion planning.

Experience

Over six decades of continuous practice in industrial facility design. The portfolio spans compact coastal refineries and craft-scale dairies, brownfield upgrades of active plants, multi-phase masterplans and full new-build processing facilities - in Norway and internationally.

What sets us apart

Process understanding. We design buildings around production lines, hygienic zones, material flows and equipment - not the other way around. This means fewer compromises during construction, lower long-term operational cost, and facilities that can grow without being rebuilt.
