Director opens when the inbound traffic volumes reach a level that APP can't manage alone. When volumes reduce again Director closes down and acft stay with App from the entry to the TMA at 45DME (45nm from the airport) until the handoff to Tower.
It all depends on the workload in the TMA. Sometimes two APP and two directors + the departure guys. At very quiet times one controller covers the whole TMA.
The App and Director controllers sit at one bank of screens a metre or two away from each other.
