Visualize the interior of a compact Attefallshus showcasing a dedicated sleeping area. The design should be minimalist and functional, fitting within the house's modest dimensions. The bed should be positioned to optimize the available space, with built-in storage solutions like drawers or shelves to maintain a clutter-free environment. Incorporate elements such as a large window or strategically placed lighting that offer a warm ambiance and enhance the room's coziness. The color palette should be neutral and soothing, with textiles and materials that add a touch of comfort and luxury to the small sleeping space, all encapsulated within the simple yet elegant Scandinavian design ethos of an Attefallshus.
