This home is really just the two rooms (& a little landscaping) that make up my grand staircase or foyer. I made the stair case by making the house diagonal with medium wall height. Stairs go to an L-shape that reach a platform where another small set of stairs reach the top. There are curved platforms on the sides of the stairs at the top to give a rounded look. Sims can stand on the platform. It is usable. :) #grandstairs #grandstaircase #stairs #platforms
