How to add another room to your sims house?

To add another room go into build mode on the right side it has a little picture of a lounge or table or something. Once you press on that a list of things come up and you press rooms. From there on you just have to either expand a room or add a room by dragging from the beginning of where you want you're room to be to the end of where you want it to be.
Hope this helped! 😃

First you have you have to put down a door then you go to where you buy furniture press on the house button and makes the room how you want it I hope this helped

So what you do us you click the little icon down the bottom (it's a chair and a lamp) then you click rooms then you click out on the grass where you want you're room to finish and pull it towards the door this really works

Go to the home store, click rooms, and drag to build another room! When you are satisfied with the room size and location click the green check mark (make sure you have enough $ to pay for the room you build)

If you want to add a room you go to the home store (the chair and lamp) then you click on the green area not the arrow then you drag and it creates a room😄. Enjoy your new room

It is simple. All you have to do is start dragging on the grass instead of the house. Hope this helped!
