This is a fairly large blacksmith which has 4 floor's, multiple rooms, a chimney that has been designed to house a tinker's smeltery and a huge patio section. I've added in access to all floor's by interwinding staircases, in a fun way. I have tried my best to light up all areas, but I probably missed some spots, so use your F7 to see if there are any dark spots, just in case.

Also, the large circular window on the rear of the building is a prime location for a create windmill. Just saying :)

The intention for this schematic was to provide a starter base that has easy to gather materials, so you can hit the ground running in any 1.16+ modpack.
