I did this in the least amount of time possible. It uses three Quatro bricks … hidden by the sloped stone wall.
Nice! What’s up with those Technic pins in the (I’m presuming) stairs? Did you just use 2×4 dark gray bricks with pins on both sides, and tan 1×2 w/ Technic pin holes to maintain the color on the sides? Or are they trapdoors or something? o_O
