Sealmount Sphere and dome blueprints 7 × 7 Minecraft 7×7 Sphere and Dome: Layer-by-Layer Blueprint
A hollow sphere 7 blocks across, 1 block thick, takes 98 blocks in 7 layers. The dome is its top 4 layers: 57 blocks. A solid sphere takes 179.

Open this sphere in the generator Open the dome
There you can change the shell thickness, make it solid or oval, or pick another height, then check off each row as you build.
Charts show the hollow sphere with a shell 1 block thick, in full blocks. The dome is its top half; the dome's bottom layer has the same outer edge as the Circle generator's circle of the same diameter. Layer 1 is the bottom. Rows run north to south and columns west to east, both counted from 1. Every “skip” is counted from the west edge. Rows without blocks are left out. How the calculations work

The dome: layers 4–7
For a dome, build only these 4 layers. Sphere layer 4 is dome layer 1, the ring that stands on the ground or on a round tower wall.
