Evil Villains Lair .. making a start ....underground dock

 A list of items under consideration to include in the secret base is:

• Meeting Room
• Villains appartment
• Operations/Control room
• Test Facility
• Machine Room (generators..)
• Warehouse (with admin office)
• Garage
• Minion's Barracks
• Firing range
• Prisoner control office and cells
• W.C. and showers ?
• Villains escape route
• Underground dock (or submarine pen)

I decided to start on the underground dock as I can re-use my harbour modules and add some new walls.

The walls are 2 inches high to match my other underground passageways and rooms - some of these can be used as well.
