ArchitectureCraft (formerly called Greg's Blocks) is a mod for the game Minecraft. It provides blocks for creating various architectural features that can't otherwise be achieved easily or at all. Currently included are blocks for building sloping roofs, pillars and rounded corners, and windows with frames.




ArchitectureCraft is a Forge-based mod, so if you haven't done so already, you will need to install Forge. See the Download section below for recommended versions.


ArchitectureCraft has been tested with the following versions of Minecraft and Forge. It may or may not work with other versions.
