Overview

Prefab is a powerful building utility mod designed to streamline the base-building process in Minecraft. Instead of spending hours gathering materials and placing blocks manually, players can craft specialized Blueprints that instantly generate entire buildings. The mod includes everything from basic starter shelters and massive storage warehouses to complex automated farms and defensive bunkers.

One of the mod's standout features is the Structure Preview system, which allows players to see a 'ghost' version of the building in the world before committing to the placement. This ensures that structures fit perfectly within the terrain and are oriented correctly. Prefab is designed to be survival-friendly, balancing the convenience of instant building with the requirement of 'Compressed' blocks, which represent the massive amount of raw materials needed for such large constructions.

Frequently asked questions

How do I place a Prefab structure like a House or Farm?

Use the structure's item form on the ground; it spawns the corresponding building at that location. Structures such as House, Farm, Modern, Warehouse, and their Improved variants are all placed this way.

What does the Structure Scanner do?

It is a craftable item used to scan and capture existing builds so you can save them as placeable structures. It is the tool tied to creating your own prefab entries.

What is the Bulldozer used for?

The Bulldozer is an item that clears terrain or structures in an area to make room for placing prefabs. A Creative Bulldozer variant also exists for unrestricted clearing.

How do I craft Quartz-Crete?

Quartz-Crete is produced via a crafting recipe and serves as the base block for its variants. From it you can craft Quartz-Crete Bricks, Pillar, Slab, Stairs, and Wall, plus Chiseled and Smooth Quartz-Crete forms.

How do I make Compressed Stone or Compressed Dirt?

Compressed Stone and Compressed Dirt are crafted by combining their base materials. They can be compressed further into Double Compressed and Triple Compressed Stone, and Double Compressed Dirt.

What are the compressed blocks used for?

Compressed Stone, Dirt, Glowstone, Obsidian, and Quartz-Crete exist as storage/decoration blocks in single, double, and (for some) triple compressed tiers. They are crafted from their uncompressed counterparts and can be used as building material.

How do I get a Swift Blade or Sickle?

Swift Blades and Sickles are craftable tools available in multiple material tiers including Stone, Iron, Gold, Diamond, Netherite, Copper, Bronze, Steel, Osmium, and Obsidian. Each tier is made from its corresponding material via crafting.

What do Sickles harvest?

Sickles such as the Stone, Iron, Gold, Diamond, and Netherite Sickle are used to harvest crops. Harvested crops appear as Bunch of Beets, Bunch of Carrots, and Bunch of Potatoes, which can be packed into Crates.

How do I store crops like beets, carrots, and potatoes?

Combine harvested Bunches into Crates of Beets, Carrots, or Potatoes. Eggs can similarly be stored as a Clutch of Eggs or Carton of Eggs, and timber as Bundle, Heap, or Ton of Timber.

What is the Drafter for?

The Drafter is a craftable block associated with creating or defining prefab structures. It is used alongside the Structure Scanner when building custom prefabs.

How do Light Switch, Dark Lamp, and Paper Lantern work?

Light Switch, Dark Lamp, and Paper Lantern are craftable lighting blocks. Coil of Lanterns and String of Lanterns are also craftable for hanging multiple lanterns at once.

What are Boundary Block and Phasic Block?

Boundary Block and Phasic Block are craftable blocks used as part of prefab structures, typically for defining edges or special regions. They can be placed like normal blocks once crafted.
