🏗️ Expanded Building

Plan your build in Creative. Pay for it in Survival. Let a builder put it up for you.

Expanded Building gives you a protected Creative planning mode inside a marked-off site. Design freely, finish the plan, and the world snaps back exactly as it was — your design stays behind as a ghost blueprint. Hand the required materials to a Builder NPC, and he puts your building up block by block, in real Survival, using real resources.

No creative items leak out. No duplication. Nothing is built for free.

✨ How it works

  1. 🪄 Left-click a block with the Builder's Wand to set corner one, right-click for corner two.
  2. 📐 The site is marked on the ground and spans the full world height — cellars and towers included.
  3. 🎨 Your inventory and game mode are safely stored away and you switch to protected Creative. Build whatever you like inside the site.
  4. ⛏️ Clear terrain while you plan. Level a hill, dig out a cellar, remove the grass that's in your way.
  5. ✅ Finish the plan at the builder. The site is restored to the exact state it was in, and your real inventory comes back.
  6. 👻 Your design stays visible as a ghost: blue for blocks to place, red for ground to clear.
  7. 📦 Hand over the materials the blueprint needs, plus the builder's wage.
  8. 🧰 If the plan clears any ground, the builder needs tools. Put them in his chest — he wears them down as he digs, and stops when there is nothing usable left.
  9. 🔨 Start the build and watch it go up.

📐 Save, share and place blueprints

A finished plan does not have to stay where you drew it.

  • 💾 Save a blueprint to a file, and share it — someone else drops it in their folder and builds the same thing.
  • 👀 Load it and walk it into place. The blueprint appears as a live preview around you and follows you as you move. It is green while it fits, red when it would hang over the edge.
  • 🖱️ Right-click to confirm, sneak + right-click to cancel. Nothing is written until you click, so aiming costs nothing.
  • 🔄 Rotate it in 90° steps — stairs, doors, fences and beds turn with it — and shift it up or down for cellars.
  • ⛰️ Pasting onto a slope just works: the blueprint clears its own footprint, so terrain never pokes up through your floor.

✏️ Change your mind later

Reopen a finished plan at any time — even in the middle of a build. The builder pauses, your design comes back as editable blocks, and you carry on where you left off.

  • Blocks already standing are never charged twice.
  • Add to the plan and only the difference has to be paid before the build resumes.
  • Remove from it and the overpayment comes straight back.

⚡ Build speed

A large project would otherwise run for hours, so the builder can be hurried along — for a price. Switch the pace any time, even mid-build.

Speed Building Clearing 5000 blocks Wage
1x 1 block/s 2 blocks/s ~83 min base fee
4x 4 blocks/s 10 blocks/s ~21 min 2× base fee
20x 20 blocks/s 20 blocks/s ~4 min 5× base fee

Drop back to a slower pace and the difference is refunded immediately — paying for a fast builder up front is never a one-way street.

🔒 Your build site is protected

An active site is guarded at a single choke point in the world, which means it is safe from all of this at once:

  • 💥 Explosions, creepers, TNT and withers
  • 🔥 Fire spread
  • 💧 Water and lava flowing in
  • 🧨 Pistons pushing blocks in or out
  • 🐑 Mob griefing and falling blocks
  • 👥 Other players — they cannot place, break or open anything on your site

🛟 It survives things going wrong

  • 💀 Die during planning? Your real inventory comes back, and no creative items drop.
  • 🔌 Disconnect? The site is restored and your inventory is waiting on your next login.
  • 🚶 Wander off? Planning ends on its own and your plan is saved, not lost — walk back to the builder and carry on.
  • 💣 Server crash mid-build? Material is journaled to disk before the world is touched, so nothing is duplicated and nothing is lost.
  • 🧙 Builder gone? /eb recovernpc puts him back.

🪄 Getting the wand

The Builder's Wand is crafted from one emerald and two sticks, and the recipe is known from the very start — no unlock, no grinding. You'll also find it in the Tools & Utilities creative tab.

 S       S = Stick
