Took about 7 hours to build totalt.

Started first with rails underground, later stages I was thinking if I could fit a whole house that goes from mountain top all the way down... with 3 floors + underground pool with, all is like surrounded by trees (the mountain).




I used about 17k+ stones so ya, it was the longest part to build the outside, when I did finish the 3 floors (not the roof, I built that nearly last). 

Hope you all enjoy this huge mountain house/undergound house.
