This add on room is an addition to an existing scene. It is a piece of furniture that you move and place to create a small separate addition to an existing place... It is a great way to increase space in an other wise too-small scene. You can scale it up to make it bigger.. or shrink it down for a smaller room. Stack them on top of each other to create multiple levels! A great way to customize your scene to fit everything you need! It is empty.. you add whatever you need to it, being furniture, decorations or pose spots.
