Sims free play. I have unlocked the elevators. How do I install them into my house? I have expanded a room and have cleared all items in the room thinking there was not enough space. It's the Toyko Retreat house. I have also made this house 3 stories thinking it needed more than 2 floors to install elevator. Weird thing is I also can not install any of the staircases and / or the fire poles. Can you just not make this type of house more than one level? Any help is greatly appreciated!! Thank you!!
