When I was a kid, I found inspiration in a local department store's annual Halloween-to-Christmas HO train setup. It was a (relatively) huge setup behind a plexiglass sneeze and fingers shield, but what fascinated me was the Haunted House.
It was sited on a hill significantly higher than the surrounding terrain and settled next to a graveyard (of course). I couldn't tell *what* the original kit was (other than they probably had it on the shelves for sale), but this Polar Lights BATES MOTEL gives you the jist (

Whoever built it had a sense of humor, since the grounds and windows where filled with all sorts of Easter Egg details barely visible from the edge of the display.
Since then, I've tripped across similar inspirations.
Like Kris Kuksi's works, from his framed creations to his CHURCH TANK

Then there's the Chapman Brothers' Hellscapes.
