Actually, it sounds to me like you're talking about using prisms the other 
way up to what I was suggesting.

My technique is to define a spline that follows the base of a wall all 
around the room with a slightly larger section of spline running around 
outside it, so that when you extrude it upwards it gives you a thin walled 
hollow tube the shape of the room. You can then use CSG to punch door holes 
and window holes into the sides of the walls.

The main benefit of this is that you can apply textures up the height of the 
wall and they only affect the one room. The next room along is defined as a 
separate prism and therefore has it's own textures.

If you use Inkscape (a vector graphics editor) to export bezier curves as 
POV-Ray prisms it also means you get a very pretty floor plan in Inkscape as 
a by-product.

I'll post a couple of images in povray.binaries.images when I get a moment 
to illustrate what I mean.

Regards,
Chris B.
