Tucked beside the saloon bar — mechanical systems and a private, lockable space for the caretaker, separate from the open event floor.

The green box marks the caretaker lock-off room directly on the labeled plan — tucked right where the saloon bar wall meets the kitchen/pantry corner, confirming the adjacency called out below.
Dimensioned CAD plan side-by-side with the 3D room planner render — same approach used on the kitchen and simulator pages to confirm equipment fits the footprint before it's installed.

Room Dimensions
Equipment Confirmed
Open item: furnace ductwork routing through this room and into the main floor hasn't been laid out yet — flag for the mechanical sub before the enclosure/framing locks the chase dimensions in.
Mechanical Systems
Houses the building's mechanical infrastructure — ties into the split 200A electrical service (new transformer, independent panels for house + shop) and the plumbing chase shared with the kitchen, bar, and bathroom. Confirmed equipment: a water heater and a furnace (ductwork routing TBD).
Caretaker Lock-Off
A private, securable space for the caretaker — distinct from the Welcome Center / caretaker house next door, this gives on-site staff a lockable spot inside the Party Barn itself during events.
Related concept: the caretaker parking & mud room access flow working concept covers how caretakers move between parking, this zone, and the rest of the building on both everyday and event days.
