A multi-purpose unit configured for fire usage having a body with an interior volume selectively closable by doors attached to sidewalls spaced between a base and a top. The interior volume contains spaces for grilling, baking, and heating. The heating space houses a grate to support a heat source. The grate is positionable between a first position generally adjacent the base and a second position generally adjacent the baking or grilling space. The intensity of heat in the baking and grilling spaces is adjusted by positing the heat source closer to or further from the space. In one embodiment the heating space may be exposed by selectively opening one or more doors over the space for use as an outdoor fire pit.
