So yeah, this is something I have been working on a bit since the game came out, it's not survival. But I plan on making something similar yet smaller in my survival server on a floating island.
More progress has been made since this video.
Structure is visible at about 00:55 seconds.
Tell me what you think, I tried to get the dimensions and placement of things fairly accurate, a few compromises were made a long the way. But for the majority I am rather happy. Remember this is about 66% finished and still has a lot of bulk work to be finished.
