yes, just like in the sims 2 you can have multiple floors in a lot
Unfortunately you can not.
You can build 2 floors on Sims 1
you can make a house with 2 floors in both sims 1 and sims 2.
in Sims 3 on xbox 360 you can. So I am pretty sure you can in all sims 3
have them go on the computer or call and select move out.
Yes, you can build your house in The Sims 3. However, building a house in The Sims 3 requires a certain amount of skill, especially for houses with multiple floors.
Yup, up to 5 floors!
I don't think you can, but they can move in with you if you are partners or best friends.
You have to go to a computer, phone, or newspaper and then click the "move" option.
Sims have to go potty.
when they move out, they will enter The Clipboard (the place where the Sims are kept after you've made them but before you move them into a house. From there, you can move them into a new lot to play them.
