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

Mengapa ini penting

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.
