Instant Structures Mod for Minecraft 1.17.1/1.16.5/1.15.2/1.14.4

The Instant Structures Mod or ISM for short is not the first mod of its kind in Minecraft. For a long time now, people have been tired of building the same structures over and over again every time they switch over and go to a new Minecraft world. This mod, like others of its kind, allows the player to place entire structures by putting down a single block. Whole houses, roller coasters, mansions, towers and more can all be created with a click of the mouse, taking much of the work out of populating your Minecraft worlds with structures and saving you from building that thousandth mob spawner.


You can’t just build whatever you want wherever you want, however. You need enough flat land for your structure to spawn upon, or else it won’t work. To place structures with the Instant Structures Mod, right click on the ground to see if your structure will fit in the bounded area, which will be highlighted on your screen. If it will, then just click yes and the building will erect; if it won’t, you’ll need to move to another location. Naturally this mod is best on super flat worlds, but if you take the time to create a level plane, it will work in standard worlds just as well.

  1. I don’t get why people make things as awesome as this and then limit it to forge servers when bukkit is clearly the way forward. Please make this a plugin or it’s useless to 99% of people that want to play online.

    • There are far more resources available for the modding community than there are available for the plugin community because mods give you a lot more flexibility, which is also why people don;t use plugins nearly as much as you think they do.

  2. The mod installed perfectly but when I put a structure it lags and then it crashes, please fix that men,the mod is awesome

  3. Crashes right off the bat. Not sure why…maybe has a clash with pixelmon and a couple of others…might want to make it more compatible. Now I have to try to find another one. Disappointed.

  4. I’m trying to get of the mod of of mine craft but it won’t come off its a virus. And it always crashes me out of my minecraft account

    • just because it dose not work dose not mean its a virus. to fix it, open minecraft go to accounts and edit the forge one, click on allow JVM arguments, and change 1G to 3G

  5. I’ve downloaded this before, taken it off, and it worked fine. Didn’t show up as a virus or anything like that on my Mac… just a little slow.

  6. Does it not work for Mac? MaggiCraft said Macs have “problems” with this mod. If any of u have a mac and downloaded fine, plz give me the link you downloaded this mod off. thx
