ArchitectureCraft - TridentMC Version
The most recent builds are always available on the Trident CI
From Original post: ArchitectureCraft provides a wide variety of good-looking architectural features including sloped roofs, glazable window frames, arches and other rounded blocks, classical pillars and entablatures, and railings for balconies and stairways. ArchitectureCraft blocks may be made from almost any vanilla material and many materials added by mods as well.
Due to lack of activity from the original developer I've updated ArchitectureCraft to 1.12, currently this is in early stages as far as the codebase goes but everything should work fine.
