Playful steampunk design turns this kids’ room into a mini submersible. A riveted copper bunk with brass porthole, propeller, guardrail and wood ladder anchors the space. A black chalkboard wall with a hand-drawn world map meets warm oak herringbone flooring. Exposed copper pipes and steel ductwork line the ceiling, as Edison bulbs cast amber light. Teal bedding softens the metal finishes and adds nautical color.
