The first progress of my mega base is the planning phase for the layout. I was thinking of every possible structure I could fit at this stage.

---

I made a progress of managing the height of each lower platforms. At this point, I'm still thinking of the possible height of each pillars and the layout of the base.

---

I use polished blackstones to decide the height of each pillars. For the middle cylinder, I made a smaller cylinder for my base layout.

---

All pillars are now built with white concrete and has been built according to its height. I'm still thinking of what could be the possible height for the smaller cylinder. I decide to add a little detail on each pillars.

---

I've finished building the smaller cylinder and start planning for the last cylinder with another pillars to the very top where it will reach the top. But before I commence building the last cylinder, I decide to build the sphere on the very top first to see the possible height limit. Unfortunate, the sphere didn't touched the max height limit so I leave it like that.

---

The layout is now finished and I stop here to think what could be the possible detail I'm going to add to make the tower look great.

---

A minor detail progress in the exterior part of the tower. Most progress I've been doing was from the interior and that includes the villager trading floors and the underwater level where I'm going to put my storage room.

I added more planning and this would be the final size of the Mega Base. I made domes as apartments and the back (right side of the 1st image) is the railroad and cargo bay but I haven't decide what else I should add. The villager hall (2nd Image) is almost complete and only 3 fletchers left remaining for Potion Arrows trade. The storage room (3rd Image) is located underneath the ocean level. The beacon will be removed after I finish the iron farm. Pillars and corals for underwater decorations (4th Image).
