Modelling Fassades

Hi Blender-Fans,

i just started with blender. Today I found a tutorial for the game cities XL:

I also would like to know if i can do this kind of stuff (using texture and than extruding the object) in blender. If yes … could anyone tell me a link to a similar tutorial?

Best regards,
torikage.
