The constraint
The nursery had to go inside an existing building where excavation was not possible. Tanks, drains and the treatment loop all had to fit without digging.
The configuration
- , 240 m³ of culture volume11 tanks
- , inside the existing buildingIndoor
- No excavation
Why it matters
Many farms start in a building that already exists. This project shows a RAS can be fitted to the building, not the other way round.
