Resources required for different Tier Structures?

Howdy all. Since I sold my Blight plot back to the Empire and can't check it myself, I was wondering if someone has put together a list of the specific resources/pieces required for different tier structures.

I am putting pieces into Guild silos as I level (to use when I actually get my lair) and am starting on T2 now and I don't want to save things I won't use. For example, we can make Imbued Iron and Silver bars. Seemed intuitive to me that the Imb Iron would be used in construction and I was saving those until I did the Lairshaping Mastery II task and it was stated we like to use Imb Silver bars since they are prettier. Now I am afraid I have saved a bunch of parts I won't need. On the other hand, Mild Excoriation of Earth uses Iron bars and Slate bricks, so I could now see it either way.

Long way to ask the question, but hey...I'm a long-winded dragon!

Thanks,
