Slide in Sideways

There are not many apartments that have their own internal slide. From the top floor to the open plan bottom floor, the designers of the Kiev slide apartment have done away with a staircase and replaced it with a slide. Cool idea that most of us would love to have if we had the appropriate two or three storey home, but let's face it, practically speaking, it probably wouldn't work for most homes or families. 
Still, it’s a beautiful home complete with skylights to let in lots of natural light and we admire than rather than go through all the 'What ifs' and 'Why nots', they’ve gone ahead and said, "Hell yeah, let's do it!" If you were to design your perfect home with no barriers, no restrictions, to be your haven, exactly the way you wanted it, what would you do?
