A very easy model, given the complexity of the structure. A beautiful piece to display is your table. Serve as a great headquarters for a party of adventurers. You can repeat floors and make it as tall as you want! I made mine gluing the sheets to cereal cardboard boxes, that way it is almost indestructible to any tabletop gaming use.
My only peeve is the little roof piece, that don't have a way to fix on the small structure of the roof, and keeps falling off.
