How do you add a room in Sims Freeplay?

Answer 1

In order to add a Sim to your city, you can do one of two things. You can build a house (depending on your taste, it could be rather costly) and add a Sim once it's built OR you could buy a crib which will give you the prompt to add a baby Sim. Hope that helped.

Answer 2

You go into buy mode then click the little house and build the room how big or wide you want it.Hopee this helps :)
