This is a 9 grid 4 story high SPIRAL staircase, works with the short wall hight only. #deligracy #TheSimSupply #JamesTurner #Semaj We needed a spiral staircase in the game sooooo... I made one. PLEASE PLEASE use it in a build, The 313 part of my name is because im from Detroit Michigan. #Detroit #313 Oh yeah!! you can remove the center walls if you want!!!! Looks Great free standing, I only added the wall because it would need aomething to grasp IRL.
