The Swedish company Jabo has launched “Steps 15,” a small prefab house with a lot of ingenious features. The outdoor staircase that leads up to the roof terrace has plant containers and hides a retractable outdoor kitchen. On the opposite side is placed a small storage room and a bench that also conceals storage. Large sliding glass doors and windows on three sides make this a very contemporary guest house, hobby room or cabin. “Steps 15” is designed by architect Rahel Belatchew Lerdell.
