This is a simple Metalworks build that I've made as small as possible, so it's easy to move around and to save your your game data.

It has all the essentials: two smelters, two blast furnaces, and two kilns. The building is 8x8, and the vbuild does not contain terrain. There are two possibilities for the radius: 15 units from the center. This is because the radius has to be a power of two, and the extra five units are for the extra possibilities.

The building has a simple layout: it has a single chest in the center, and each side has an exit.

It is very easy to build, and there are some built-in tools for ease of construction.

If you do not know how to build a Metalworks, this is a very good place to start.
