I would like to use Carrara to mix a real-life background with a 3d render. The project I am trying to visualize is what this room would look like with a dining area raised slightly above the carpet and floored with wood laminate. The dining area would extend from the back wall to the midway down the radiator. So, Basically what I need to do is place a 3d box type object on the ground that follows the contours of the wall and which could then have chairs and tables etc. placed on it to see what it would look like. Would love to know how to do this with Carrara as it would help me learn something about it (as well as helping me decide whether or not to do this actually in my room!)

If anyone is up for a challenge I could post a better photo of the room and remove the plant and table & chairs!
