Any tutorials for doing interiors?

Hi all,
I'm looking for help on how I get started for making an interior for a game.

Is each wall it's own group?
I mean do I make the walls, floors and ceilings basically modified cubes and then join them all together, or is there a better way to do it?

Or do I just start with say the floor or something and extrude / cover the walls and ceiling?

Or am I way off and there's an easier way to do it?

Thanks for any info!

Ok, so I figured out I could do this with 'shell' and it works.
Only problem is that when I import it into Unity the lights show through the seams..

Oh well, guess that's a topic for another forum.
