The Assembly Workshop is a location in Nexus Tower. It serves as the hub for the Assembly area of the tower, with two Brick Warps leading to the Assembly Storerooms, as well as connections to the Nexus Core and outer hallways of the tower. Central to the hub is a tube of whirling bricks, with one of Johnny Thunder's Treasure Chests found on top. There are also several Flags in the scaffolding above the Assembly Workshop, which can be collected by jumping down from the Assembly Storerooms.
