Designed for play and sleep, this industrial kids’ room pairs corrugated galvanized steel walls with exposed ductwork and a concrete-look platform bed. A pale plywood climbing wall with lime-green holds and a birch trunk adds adventure, while black metal racking with a fold-down desk organizes gear above a red toolbox. Speckled black rubber flooring grounds the space, teal bedding adds color, and a skylight plus linear LEDs deliver bright, even light.
