I think the overall time it took to build from beginning (after water was cleared) to finished product was 4-5 days. It was a lot of work, but well worth it!

Did you put a roof on the guardian spawning area? Seems its open from the screenshots. Just an info, guardian spawn efficiently if they dont have sky access.

Now next on your task is to mob proof the area surrounding your guardian grinder. Thats like another 4-5 days work. Lol.

Yep, I built an entire island above my spawner as camouflage and the area around my spawner is mob proof. ^^

@jamlbon Omg it looks amazing , good to know where 50% of my base came from ;P

Wait... that island was? No... I was there like 5 days ago!
Sorry about the big red X on the small island near it :/
