4 production rooms + buffer spine — complete acoustic data, treatment specifications, and HVAC routing for each space.
The buffer spine is the acoustic separation wall between the west zone (VO Live + Control) and the east zone (Studio + Editing). It is the only permitted HVAC duct routing path between zones and serves as the circulation corridor via D2 and D4.
