If you ever live in an attic room, you would understand how useful this window system is. It is easy to get some skylight in these type of room, but you can’t really get out. A window design company called Fakro, has developed an innovative skylight that can transform a window into a balcony! When open the window, the upper top hung sash (of the window) opens upwards, whereas the lower sash can be tilted forwards, allowing easy access to the balcony recess. Met with a slide rail inside, Fakro’s design can transform a room’s architecture without expensive renovations. Really creative and it will definitely help to open up the space for attic room.
