Help building a new temple

I’ve got a geared level 100 blood mage which I have the fub temple built on, but I just finished leveling an oracle with the intention of building the milky temple. However in milkys video he doesn’t explain how to create the layout he posted a link to.

I wanted to know if anyone has built this temple who can help me, or if there’s another better temple with a guide available? I don’t mind a challenge but I’m not good at just looking at a picture and figuring it out from scratch.
