This project is a 95% accurate recreation of a real-world location: https://tinyurl.com/lakesubstation. I created this originally as a college project in 2009 as part of my advanced level design class at the Art Institute of Tampa. I have a ton of reference photos that I used along with Google Earth for measurements and proportions.
I’m a huge fan of electrical installations. They look like metal skeletons, especially at night. With the right lighting, they’re very atmospheric and work as great hard-surface practice too!
