Well, you would have to do a volume calculation (*) instead of area. Take the scaling factors (which are actually areas) and multiple by the desired height of the product. Do this in centimeters is best; what you have at the end is millliters (one cubic cm is one mL). Now put your castle on a scale and tare it out. Fill with water, and measure in kg; this is how many liters your castle holds. Multiple by 1000 to get mL. You can now easily convert your flat pan scaling to scale your castle.
PK
(*) technically you should be doing a volume any, since pans have sloping sides and it does affect the calculation, but for flat-land it is a fine approximation)
(**) Yes, I think about these things
EDIT: Dammit, frank beat me to it. I was reducing the procedure too much!
Pauls method would work fine too...in Canada...
