Design elaborate buildings within a minute. Draw a ground plan out of rooms, towers and roofs; the mod decorates it with walls, windows, roofing and detail in the theme you picked; choose a block palette; then print the result straight into your world or save it as a schematic.

This is a maintained, open-source (MIT) port of simibubi's original The Mighty Architect. The themes, designs and the core idea are his; this port keeps them working on current Minecraft versions, on Fabric, NeoForge and Forge.

How it plays

• Press G to open the architect menu. Everything happens from there — no items or recipes.
• Compose: pick a theme (Medieval, Modern, Town House or Cattingham Palace), then click in the world to place rooms and towers, stack floors with the scroll wheel, and reshape or re-roll parts of the ground plan. A blueprint-tinted preview shows the building as you go.
• Choose materials: open the palette picker and click a palette; the preview repaints with those blocks. You can build your own palettes and save them.
• Finish: print the building into the world, or save it as an .nbt structure file for structure blocks or other schematic tools.

Multiplayer

The mod is client-side: you can design, preview and save schematics on any server.

• Printing into the world needs operator permission, the same bar as /setblock. On a server without the mod it places blocks with ordinary commands, batched and rate-limited.
• Servers can optionally install it too. Printing then uses the mod's own packets — much faster, no command spam — and is allowed for creative-mode players or operators. Every placement is checked against the world border, spawn protection, land claims, reach and a per-player budget.

What this port changes from the original

• Versions and loaders: Fabric on every supported version, NeoForge from 1.20.3, and Forge on 1.19.4 and 1.20.1 — Minecraft 1.19.4, 1.20 – 1.20.6, 1.21.1, 1.21.4, 1.21.6, 1.21.8, 1.21.10, 1.21.11, 26.1, 26.2 and 26.3, all from one codebase.
• Security: earlier ports accepted build packets from any player. Building is now limited to creative mode or operators, and every placement is validated server-side (see Multiplayer).
• Multiplayer printing without the mod on the server, through normal commands.
• Your data in one place: your own themes and palettes live in <game folder>/mightyarchitect/, copied there on first launch; the originals are left untouched. Resource packs can ship complete themes under assets/mightyarchitect/themes/<name>/.
• Fixes and robustness: large buildings are processed over several ticks instead of freezing the game, blueprint rendering and the save/print flows were reworked for modern Minecraft, and every release is tested automatically on every supported version, including a real in-game client test.
• No extra library: only Fabric API is needed on Fabric; nothing else on NeoForge or Forge.

Each file lists exactly the Minecraft versions it was built and tested for — pick the file that matches your version.

Server admins: do not run a build older than 2.0.0 on a server; those accepted build packets from any player without checking permissions.

Bug reports are welcome on the project's issue tracker (please include your Minecraft version and loader).

The Mighty Architectury

Design elaborate buildings within a minute. Draw a ground plan out of rooms, towers and roofs; the mod decorates it with walls, windows, roofing and detail in the theme you picked; choose a block palette; then print the result straight into your world or save it as a schematic.

Press G to get started.

A maintained port of simibubi's original The Mighty Architect, with his themes and designs.

Versions and loaders

Each file lists exactly the Minecraft versions it was built and tested for, and loaders will refuse it on anything else — so pick the file that matches your version.

Requires: Fabric API on Fabric. Nothing else — Architectury API is no longer needed as of 2.0.0.

Multiplayer

The mod is client-side: you can design, preview and save schematics on any server.

• Printing into the world needs operator permission, the same bar as /setblock. On a server without the mod it places blocks with ordinary commands, batched and rate-limited.
• Servers can optionally install it too. Printing then uses the mod's own packets — much faster, no command spam — and is allowed for creative-mode players or operators. Every placement is checked against world border, spawn protection, claims, reach and a per-player budget.

Server admins: do not run a 0.x build on a server. Versions before 2.0.0 accepted build packets from any player without checking permissions. Update to 2.0.0 or newer, or simply remove the mod from the server — players lose nothing. If a server ever ran an older build, also check /gamerule logAdminCommands.

Your themes and palettes

Since 2.0.0 your own themes and palettes live in <game folder>/mightyarchitect/. Existing ones are copied there on first launch; the originals are left untouched. Resource packs can now ship complete themes under assets/mightyarchitect/themes/<name>/.
