File this under: impractical home design features that are tempting anyway. Located in a historic building in Gothenburg, Sweden, this 635-square-foot loft can probably stay bright enough through the darkest of winters, thanks to a 65-square-foot skylight accessible via an enticing (but railless) spiral staircase. Half-way up, there's a mezzanine area that can be used for anything from a tiny garden to an art studio, and all the way up, the roof becomes the ultimate indoor/outdoor hangout spot. The rest of the space is just as free-spirited: there's an open living and dining area and a sliding door hiding a bedroom with storage area. The one sign of restraint is the monochrome color scheme, as Scandinavians are wont to do.
