Thommesen Architecture is an independent practice in Trondheim, Norway, that plans and designs production facilities for seafood, aquaculture, dairy and food processing. Founded in 1964, it is family-owned and now in its third generation.

The production process drives the building. Product flow, hygienic zoning, the cold chain and equipment access set the layout, and the structure is planned for a plant that will operate and expand over 30 to 50 years.

Scope

Seafood processing, aquaculture, dairy and food production make up the core of the practice. Commissions include new plants, extensions and the rebuilding of facilities in operation, for small plants as well as large ones. Most plants are extended several times after start-up, and each extension is planned while production continues.

Experience

The practice has followed the TINE dairy at Dovre since the 1970s, and has designed facilities for Siva, the Norwegian state’s industrial development company, over several decades. Outside Norway, commissions include plants and facilities in Nigeria, Portugal, Poland, China and Jamaica.

Independence

Our role is the planning and design of the plant, which keeps our advice neutral between equipment suppliers and contractors. Clients choose suppliers freely, and the practice coordinates the building with the equipment they select. The same people follow the project through every phase until the plant is in operation.

Collaboration

We work with process equipment suppliers, food safety consultants and engineering disciplines from the first design stage. Equipment, utilities and hygiene requirements are coordinated in the design documents before construction starts. Where a plant needs approval for export to the EU, the hygiene requirements are part of the layout at the concept stage.
