insane asylum –
I have a full themed asylum. I also have a elevator that takes them into the sewer/boiler portion of the haunt. I am looking at adding a outdoor portion this season that will be like a hospital "tranquility" garden. I plan on calling it The garden of Despair. Lots of folige,statues,fountains,and of course hell on earth.
I just got back from Legendary haunt Tour and the 13th gate has an AWESOME asylum portion. I agree. Very well done. It inspired me in what direction to go with mine.
Cost wise: Im in my 4th year in a building I own. About 8000 sqft and 35% is up permament. I have a large amount of detail in my haunt and a fair amount of high end props/fx/costuming. I am at about $100k not including the building.
Good luck. Hope that helps.
