Unlocking Massive Builds with ExtraSpace: The CompactMachines Expansion
Minecraft’s modding scene is full of clever ways to save space, and CompactMachines has always been a favorite. The idea is simple: shrink entire rooms into a single block, letting you hide complex redstone contraptions, massive farms, or entire bases inside a tiny footprint. But even the most dedicated engineers eventually hit a wall — literally. The default room sizes, while generous, can feel cramped when you dream of sprawling multiblock structures. That’s where ExtraSpace steps in, a must-have addon that tears down those walls and gives you the breathing room your builds deserve.
What Is CompactMachines?
For those new to the concept, CompactMachines is a mod that lets you craft special blocks that contain pocket dimensions. Step inside one, and you’re teleported to a fully enclosed room where you can build anything you like. The outside world sees only a single block, making it perfect for keeping server lag low or hiding unsightly wiring. The standard sizes range from tiny 3x3x3 cubes to a decent 13x13x13 chamber. For many players, that’s enough — but once you start building advanced automation setups, you quickly realize that some projects simply won’t fit.
ExtraSpace: Expanding the Boundaries
ExtraSpace is an addon designed exclusively for CompactMachines, and its mission is clear: give builders the extra room they crave. By introducing larger machine sizes, it pushes the limit all the way up to a colossal 25x25x25 interior. Suddenly, those multiblock reactors, enormous Applied Energistics networks, and intricate Botania mana setups have the space they need to function without awkward compromises. No more squishing your Draconic Evolution energy core into a corner or splitting your factory across three separate machines just because the walls were closing in.
New Machine Sizes
The addon adds several new tiers, each carefully balanced to integrate seamlessly with the existing CompactMachines progression. You won’t just jump from 13x13x13 to 25x25x25 overnight; there are intermediate steps that require increasingly rare materials, keeping the sense of achievement alive. The new dimensions include:
- 15x15x15 – a modest upgrade for those who need just a little more elbow room
- 17x17x17 – ideal for mid-game factories with multiple processing lines
- 19x19x19 – where truly ambitious builds start to take shape
- 21x21x21 – a serious commitment, demanding late-game resources
- 25x25x25 – the ultimate machine, capable of housing an entire base in a single block
Each size increase feels meaningful, and the crafting recipes scale appropriately. You’ll need to venture into the Nether, the End, and possibly other dimensions to gather the necessary components, which keeps the mod integrated with your overall progression rather than feeling like a cheat.
Perfect for Large Multiblocks
The real magic of ExtraSpace becomes apparent when you tackle mods that rely on enormous structures. Think of a Mekanism fusion reactor, a Forestry multifarm complex, or a Blood Magic altar with all the bells and whistles. In the past, you might have had to build these in the overworld, cluttering your landscape and causing frame rate drops. With a 25x25x25 machine, you can enclose the entire thing, wire it up with compact cable facades, and still have room for a control room and storage. The result is a cleaner, more optimized world where performance stays smooth even on servers with dozens of players.
Automation enthusiasts will appreciate how the larger spaces allow for more elegant designs. Instead of cramming pipes and cables into every available corner, you can lay out your production lines logically, with clear pathways and maintenance access. It’s the difference between a chaotic spaghetti monster and a well-organized industrial facility — and once you experience that clarity, you’ll wonder how you ever lived without it.
Installation and Compatibility
ExtraSpace is built for Minecraft 1.12.2, a version that remains incredibly popular thanks to its massive mod library. You’ll need CompactMachines installed first, of course, and the addon slots right in without any conflicts. Getting it set up is refreshingly simple; you can even use the foxygame.net launcher, a convenient, flexible, and modern Minecraft launcher where you can download mods right from the menu, to handle the installation in a few clicks. Just search for ExtraSpace, add it to your modpack, and you’re ready to craft those bigger rooms. There are currently no plans to port this mod to newer Minecraft versions, since similar addons already exist for those releases, but for 1.12.2 loyalists, ExtraSpace remains the definitive way to expand your pocket dimensions.
Because it’s an addon rather than a standalone mod, ExtraSpace respects the original CompactMachines mechanics entirely. All existing machines continue to work, and you can upgrade or replace them at your own pace. The new blocks use the same linking system, so your tunnels, personal shrinking devices, and other gadgets will function across all sizes without a hitch.
Conclusion
ExtraSpace is one of those mods that solves a problem you didn’t realize you had until you tried it. Once you’ve built a fully automated ore processing plant inside a single 25x25x25 block, the old size limits feel almost claustrophobic. It respects the balance of CompactMachines while giving you the creative freedom to push your builds to new extremes. Whether you’re a technical player chasing the perfect factory layout or a server admin looking to reduce world bloat, this addon is a small download with a huge impact. So grab your crafting table, gather those ender pearls, and start expanding — your machines are about to get a whole lot roomier.
