Frequently asked questions

BuildSchematics is a free library of community-made Minecraft builds — houses, castles, farms, redstone contraptions and decorative structures. Every build has a 3D preview you can spin in your browser, a full material list with block counts, and a one-click download for Litematica or WorldEdit.

The point is that you can see exactly what a build looks like and what it will cost you in blocks before you download it, instead of guessing from a file name and one screenshot.

No. Browsing, previewing and downloading are free and need no account, no plugin and no sign-up. Open a build, look at it in 3D, download the file.

You do need a mod or plugin to place a schematic in your world — see the question below — but that is on the Minecraft side, not here.

Single-player and clients: Litematica is the usual choice. Drop the downloaded .litematic file into your .minecraft/schematics folder, load it in game, and it shows a ghost overlay you build into block by block.

Servers: WorldEdit pastes a .schem straight into the world. Upload the file to the server’s schematics folder, then //schem load and //paste with the right permissions.

Which file you want depends on the tool, and the download page tells you which format each build ships in.

The browser viewer opens .litematic, .schem, .nbt and .mcstructure. Builds in the library are usually .litematic or .schem.

The viewer parses the file in your browser, so nothing is uploaded to a server to render it.

Yes. The 3D viewer takes a file you drop into it and renders it the same way, with the same material list and layer-by-layer stepping. Nothing leaves your device — the parsing happens in the browser.

It is a quick way to check what is actually inside a schematic you downloaded from somewhere else.

Each build lists the version its file was saved in, which is effectively its minimum. Schematic formats are generally forward-compatible, so a build saved in an older version usually pastes fine into a newer world; the reverse is not reliable.

Builds using blocks added in a recent update will not place correctly on a server older than that update, whatever the file format says.

They are made by the Minecraft community, and each build is published under its author’s name. BuildSchematics hosts and presents them rather than claiming them.

Using a build in your own world or on your own server is what they are for. If you republish one, credit the author.

A separate set of tools on the same site for writing Minecraft commands: version-aware builders for /summon, /give, item NBT, text components, target selectors and datapack resources, so you do not have to hand-write the syntax.

They predate the build library and are kept because they work and people use them. Command syntax shifts between releases — item NBT became item components in 1.20.5 — so the output is built against a target version rather than one fixed syntax. Java is the primary target; Bedrock output appears only where the syntax has been checked.

It is a free community project. It is not an official Mojang Studios or Microsoft product and is not sponsored or endorsed by them. Minecraft and its assets remain the property of their respective owners.

Use the Contact page. For a broken build, the page URL and what went wrong (file will not open, blocks missing, preview blank) is enough to reproduce it. For a bug in the viewer or a generator, add your browser and the target Minecraft version.
