I downloaded this once before from somewhere else, but got Hovel again here at RPGnow just so it would let me rate/review/enthuse over it.
This is a fantastic paper model. It's a bit tricky to put together for beginners, because it's so intricate. The walls actually have width; the windows are recessed halfway into those walls; it's beautifully done as a simple outdoor building model, but you can lift off the roof, swing open the doors, and use the interior, all as part of the same model. It really is brilliant, and anyone that likes paper models - whether you ever even use it or not - should get this.
It warrants 5 stars even before the fact that it's free. So, 5+.
