It sounds as if it's constructed with lines rather than plines. What I'd try (save the file as something you can ruin, first, please) is the 'pedit' command.
Type pedit.
Choose a line.
It'll ask if you'd like to make it a pline. Select yes.
Choose join.
Click *all* of the lines you want to make into plines, forming a complete polygon.
Try extruding that. That should work for you, but it'll extrude into solid blocks. You can't walk through solid blocks.
For the whole building, I'd make one large polyline for the outside walls, and then make the halls and rooms into a smaller, interior polyline.
Extrude both, and then use 'subtract' to cut out the rooms and things.
It's not a perfect way of doing things, but it should work okay. It's not *horribly* detailed, but it could be, if you're willing to put the work into it.
