Minecraft Broach Spire Generator

A broach spire is useful when a square tower needs to become an octagonal or pointed roof. This generator helps plan church towers, gothic steeples, fantasy keeps, and roof transitions that are hard to judge by eye.

How To Use It

Adjust the base, transition, and spire proportions to match your tower. The layer map shows how the square footprint changes as the roof rises.

Good Minecraft Uses

  • church towers
  • gothic steeples
  • fantasy keeps
  • bell towers
  • square-to-octagon roof transitions

Build Tips

  • Start by matching the square base to your tower footprint, then tune the upper height for the silhouette.
  • Use the layer map to keep the transition symmetrical on all sides.
