Each tile was printed in high-quality and on cardstock. I then sprayed two layers of matte sealant on them. Next came two layers of mod podge, that I rolled on with a brayer. I then cut them out, applied white-glue to their backs using a sponge-brush, and stuck them to cut-to-fit pieces of mounting board. These pieces were then stuck to cut-to-fit pieces of peel-and-stick magnetic sheets.
I bought a 24"x36" sheet of 26-gauge steel, and painted it with outdoor vinyl house-paint.
Pieces all sorted and ready to assemble:

Build out halls...

Build out NE wing...

Build out SE wing...

Build out SW wing...

Build out NW wing...

Here is a familiar Quest from Return of the Witch Lord:

Again, but at table view:

One possible way to dead-end areas...

And, a pair of Bill Dasks' excellent reproductions get a little showing off:

I do now actually have every single tile from every Quest Pack built and ready to use, I am just rather lazy when it comes to taking photos. If there is interest, I will get around to building out and snapping shots of any Quest.
Building one of these is not really that hard, and not very expensive. I lucked out and was given a gift-card to Hobby Lobby to expend for mine.
You will need:
Color Printer (I was able to print off all the tiles using one cartridge of color. Print them using adobe acrobat, high-quality, and under advanced settings let the printer determine color settings, and unclick the setting to save black)
You'll need at least 24"x30" worth of the following, just for the rooms and hallways, they are listed in the sizes I was able to find them in:
8.5"x11" white cardstock
8.5"x11" peel and stick magnetic sheets ($3.99 per)
24"x36" 26-gauge steel sheet ($19.99)
16"x24" Mounting board, or chipboard ($3.99 per)
