How to Build a Dome in Minecraft

By PickaxeKit Editorial Team · Updated 2026-11-08

Choose a base width, set the height to about half of it, and build ring by ring from the bottom up. A 25-wide, 13-tall hollow dome takes 1,365 blocks.

Plan the size first

A dome is the top half of a sphere. Its base is a circle, and each layer above is a slightly smaller circle until the roof closes. The height you choose changes the shape: half the width gives a classic round dome, less gives a flat dome, more gives a tall, egg-shaped roof.

Build it layer by layer

1. Mark the centre of your base with one block.
2. Open the Dome Generator, enter your width and height, and build layer 1 (the base ring).
3. Stand on the base ring, go up one block, and press the next-layer button. Build that ring.
4. Repeat until the top layer closes the roof.
5. Add windows last: a wall thickness of 2 lets you cut openings without leaving holes.

• Building the roof before the walls: without the lower rings, you have nothing to stand on or count from.
• Using an even width: the centre becomes 2×2, which is harder to line up. Odd widths are easier.
• Forgetting scaffolding: tall domes are easier with scaffolding inside, which you can remove from the bottom.
