This structure is tentatively being called "Lock Down" due to its ability to drop all four draw bridges into lava making it completely secure. It also has a low to the ground sniper nest making it more practical than nests located in the clouds. A layer of glass 1 high surrounds the perimeter protecting players from accidental death. The building is constructed to prevent mobs from spawning in a 5 block radius. Lava on the roof discourages unwanted guests.
