A steampunk forge with a grand arch...

A steampunk forge with a grand arched entrance framed by decorative copper gears along the top. The facade is built from dark blackstone and deepslate, accented with copper trim and gold block detailing. Two arched side alcoves flank the central doorway, each lit by wall lanterns. A central pillar stands at the entrance with circular medallion patterns on the ground in front. Lava sources provide warm ambient lighting between the stonework. The overall aesthetic is dark and industrial with warm metallic accents — heavy use of blackstone, deepslate, copper blocks, gold blocks, lanterns, iron bars, and chains throughout.
