Designing a haunted house

"If you could design a haunted house, what would you name it? What types of rooms would you have? Describe, in detail, 3 of the best rooms in your haunted house."

Were I to design a haunted house, I would call it the Old Cronos Place.  Each room would be themed after a different time period and would transition from one to the other with surreal seamlessness.  I can imagine a lot of rooms would be good, but my three favorites would be unique and memorable.  The first favorite would be the Fallout Cellar, taking people into the basement into a world of Cold War paranoia, complete with radioactive glows and Communist zombies.  The second would be the Plague Room, where rats would hang from the ceilings and people in doctor masks would stalk ominously around and condemn people as being infected.  Finally, the third would be the Grand Battlefield, converting the entire backyard into one massive warzone where ghostly soldiers from every war would stare eerily at all the patrons.
