The source code is available to everyone under the MIT licence and you're very welcome to clone or fork the reposity, but keep in mind that it is mostly a proof-of-concept and the code is hardly optimized or refined. Most parameters are accessible from the "Spawner" blueprint-class, but some are hidden in ProcMeshActorBP, PlotBuilderBP and HouseBuilderBP.
