Zenith is elegantly designed so that the center of attention is loaded from every angle. It would be very difficult, near impossible, to do this with such a large building. I ran into this problem when designing castle venito. If you go with a 400x400 palace, then I suggest not using a centrally planned design.
Whatever the case, you never disappoint. I just think that a Lancaster revival would be a better use of your fortune. Lancaster is your legacy.
It's true. Sight lines are the bane of any truly large build in Minecraft. It's why it's so hard to build a great "cathedral." You would never be able to see the whole length of a proper nave.
I agree, I had that problem with my cathedral too. I managed to get a good solution for monumental ecclesiastical architecture, but it isn't ideal. I can show you some time. The trick is in area optimization and mathematics.
