Blocks for a 9-wide tower with 14-block walls
| Style | Layers | Blocks | Stacks of 64 |
|---|---|---|---|
| Lighthouse | 20 | 468 | 7 |
| Wizard tower | 25 | 669 | 10 |
| Observatory | 20 | 638 | 9 |
Counts come from the same generator as the tool above, so they always match the grid.
How to use it
- Pick lighthouse, wizard tower or observatory.
- Set the diameter and how tall the walls are; the roof is added on top.
- Build layer 1 at the bottom, then press › for each layer above it.
- Use Quarter view for big towers: each quarter of a round layer is the same, turned.
- Download a .schem or .litematic to paste it, or print every layer as a PDF.
How it works
Each block is placed if its centre falls inside the perfect shape that fits your size exactly. Hollow shapes keep only the blocks within your chosen wall thickness of the outside, so walls never have gaps. Every number on this page is calculated, not typed by hand.
Questions
What blocks look good for a wizard tower?
Stone bricks or deepslate for the walls with a dark oak, spruce or purple roof. Download the shape in one block, then swap the roof layers to another block with WorldEdit's //replace.
How do I build the lighthouse lantern?
The lantern room is the small ring above the wide walkway. Build it in glass, put a glowstone, sea lantern or redstone lamp in the middle, and top it with the cap layers.
Does this work for Minecraft Bedrock and Java?
Yes. Blocks are the same size in Java and Bedrock, so the same layout works in both editions and in every version.
Why is the centre a 2×2 square on even sizes?
An even diameter has no single middle block, so the centre falls between four blocks. Use an odd size (like 25) if you want one middle block to build from.
