is this custom, or is this from a real-life architectural structure??
Its inspired by real life architecture. Someone actually already did a build of this building, but I'm building my own with a red roof. Go google the Winter Palace Minecraft on google images. My version is larger and all the details I'm coming up are different than in that but the general layout is the same. I use it as my main inspiration, but its very hard to build alone because it is a massive project. Going from left to right of what you see in the picture. The palace covers half of the entire length of the map.
