Ouch! That's slow :(

Better not generate the boxes which you don't need that cut them out
completely. Inside the #while loop, only generate the box #if it fits
some criteria. For example,

...
#if ( !((Row>=0) & (Row<=8) & (Column >=6) & (Column <= 10)) )
  box {... whatever...
#end

If your wall has "staggered" stones (as it should), then you should
have a separate check for the left and right end of the door and use a
difference as Ken pointed out (but not the whole union, just the
bricks that you need!)

Hope this helps. I won't spoil more of your fun, learning POV does
include some banging your head against a wall <g>
