Omega mansion

omega mansion, a medium to large house built with a overhang concept and uses many simple yet effective(not really) redstone circuits and command blocks to create a "defensive wall" at night, it also comes with a seceret in the pool, which i would definetely touch.   all command blocks are located at the top of the house "curcits room" acessible by a ladder in one of the top rooms.
   
unfortunately, since it was built in 1.6.2, a glitch causes the red sand to dissapear in the wall
