Can you add a second floor in The Sims 3 for DS/3DS?

Does anyone know if it's possible to add a second floor to a house in The Sims 3 on DS/3DS? I'm playing The Sims 3: Pets for 3DS and I've googled and looked up Youtube videos with no luck. It's really weird how online reviews don't seem to even mention the issue.

The answer is easy enough, go to the roof tool and remove all roof pieces and turn off the auto roof and then add the roof when you are finished. To build up a level, either on a new build or a pre-existing house is quite easy. Go up a level in view and add floors and walls where you want them.
