Hello,
Here are some pics of my O scale Haunted House build. Used balsa wood for exposed framing, added led lights & a spook at the front door. The orange leds flicker like fire. I hope the link to the photos works.

I especially like the jack-o-lantern face along one side!

That looks fabulous! Thanks for sharing the pictures.

Awesome!!
