🏗️ 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.

🆕 New in 1.1.0: import Litematica and WorldEdit schematics straight into a project, feed the builder from a material chest, and plan chests, furnaces and signs.

✨ 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 is in your way.
5. 🚪 Doors, trapdoors and fence gates still open while you plan – right-click opens whatever is in hand, crouch + right-click places a block against it instead. Put up a wall and you can still get back behind it.
6. ✅ Finish the plan at the builder. The site is restored to the exact state it was in, and your real inventory comes back.
7. 👻 Your design stays visible as a ghost: blue for blocks to place, red for ground to clear.
8. 📦 Hand over the materials the blueprint needs, plus the builder’s wage – or point the wand at a chest and let him fetch them himself.
9. 🧰 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.
10. 🔨 Start the build and watch it go up. He walks to every block, turns to it and swings, with the sound of a block placed by hand and the debris of one broken by hand.

📐 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.

📥 Litematica and WorldEdit files – new in 1.1.0

Somebody else’s build becomes a project without rebuilding it by hand.

• 📁 Two folders are created on first start: config/expanded_building/litematic and config/expanded_building/schem. Drop the file in – no renaming needed, case does not matter, and tab completion fills the name in for you.
• ⌨️ /eb litematic load <name> and /eb schem load <name> hand the file to the same preview a native blueprint gets: walk it into place, rotate it, confirm. Nothing is written to the world until you do.
• ✅ Reads .litematic versions 1–6 with any number of regions, and Sponge .schem versions 2 and 3, gzipped or raw. save writes them back out, so a plan drawn here opens in Litematica too.
• 💨 Air is not imported as a demolition order. Every empty position in a schematic is a real palette entry – taken literally, a 50×50×50 file would be 125,000 clearing instructions that wall the building in.
• ❓ Blocks from mods you do not have are skipped and reported with a count and an id, never silently turned into air.
• 🚫 The old MCEdit .schematic is refused rather than misread – its numeric block ids stopped meaning anything back in 1.13.

📦 Getting material to the builder

• 🤝 Hand it over at the dashboard, piece by piece, or with /eb deposit <id> in one go.
• 📥 Or set a material chest: crouch + right-click a chest with the planning wand. The builder draws what the project is still short of four times a second and leaves the chest empty again – so its size never limits anything, and a hopper can keep it filled.
• 🔐 It stays your chest. The mod never places it, never removes it, never protects it, and takes only what is on the requirement list – a chest in your base loses nothing else.
• ✅ Once the requirement is covered, the project moves to Ready on its own. You do not have to walk back.
• 📋 What is still missing sorts to the top of the material list, finished lines to the bottom.

✏️ 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.

The surcharge grows with the square root of the pace, not linearly. 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.

🔒 What is protected

A build site is not a no-go zone. Only what the builder still needs is locked:

Everything else inside the site behaves like normal world. Doors, chests, furnaces, buttons and levers work, and you can place and break in Survival as usual – you can carry on building the house while the builder digs out the cellar underneath it. What he has finished is yours again: decorate it, rebuild it, tear it down.

Protection sits at a single choke point over every block change in the world, which means the open plan 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 the builder still needs

Want a site untouchable from the first click to the last? Set protectEntireSite: true.

👥 Build together

• ➕ /eb add <player> <id> lets someone else plan, deliver material, start the build and change the pace.
• 👑 Cancelling and managing members stays with the owner – a cancellation refunds whoever triggers it, and that would otherwise be a route to somebody else’s material.
• 👀 The site is visible to everyone nearby, ground marking and ghost, even while the owner is offline. Seeing and touching are deliberately two different things.

🛟 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? He is replaced automatically once you are nearby, and /eb recovernpc <id> forces it.

🪄 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 will also find it in the Tools & Utilities creative tab.

  E      E = Emerald
 S       S = Stick

⚙️ Configuration

Everything below lives in config/expanded_building.json:

• 📏 Site size – unlimited by default, and each axis can be capped on its own
• 🔢 Projects per player – 3 by default
• 🧮 Blueprint block limit – 100,000 by default
• ⏱️ Build and clearing pace, plus the maximum speed players may pick
• 💎 Emerald wage – rate, minimum, maximum and a hard ceiling
• 🚶 How far you may wander before planning mode ends
• 🪑 Block entities – chests, furnaces and signs in a blueprint, on by default since 1.1.0. They always arrive empty: a blueprint holds a block state and never NBT
• 🚰 Fluids – off by default
• 🛡️ protectEntireSite – off by default. On, a running project locks its whole footprint over the full world height, for everyone
• 🗺️ keepSiteLoaded – off by default. On, exactly one chunk is held loaded – the one the builder is standing in – so a build carries on with nobody nearby

📋 Commands

/expandedbuilding – or just /eb or /bp.

• /eb give – hand out the wand (admins)
• /eb projects – list your own active projects
• /eb menu <id> – open a project without the NPC
• /eb add|remove <player> <id> – let someone build with you, or take it back (owner)
• /eb members <id> – who is on the project
• /eb finish|deposit|start|cancel <id> – the dashboard buttons, as commands
• /eb recheck <id> – carry on after refilling tools or clearing a conflict
• /eb recovernpc <id> – re-place a lost builder
• /eb recover – resolve a stuck planning session or refund
• /eb blueprint|litematic|schem save <name> <id> – save a plan to a file
• /eb blueprint|litematic|schem list – show what you have saved
• /eb blueprint|litematic|schem load <name> – start placing one
• /eb blueprint rotate [degrees] / shift <dy> – aim it
• /eb blueprint confirm / cancel / undo – place it, drop it, take it back

Project ids can be typed as the short form shown in the lists.

📦 Requirements

• Minecraft 26.2 or 26.1.2
• Fabric Loader 0.19.3 or newer, plus Fabric API
• Java 25

On a server where players do not have the mod installed, everything still works: the dashboard falls back to a chat menu. The ghost preview is drawn by the client, so that one needs the mod on both sides.
