NBTStructureLib
NBTStructureLib brings Create jigsaw structures to Minecraft 1.7.10 Forge, letting builders assemble branching, randomised structures from block IDs typed by hand.
What it does
Structures are configured in the mod and can be restricted to chosen spawn dimensions and biomes. It can also generate simple non-jigsaw structures, which helps replace structures from other mods without causing worldgen cascading issues. Installation runs on the server side, and clients need nothing extra. The mod is published for Forge 1.7.10 only, with 0.9.3 as the latest file, and is released under the GNU General Public License v3.0 only, making it open source.

What the author says
Functions very similarly to jigsaw structures from modern versions of Minecraft, allowing for building complex randomised branching structures directly within your mod, without causing worldgen cascades or having to manually type out block IDs by hand. Structures can be configured to spawn in any dimensions or biomes…
