While an upstairs balcony is a nice feature for any home, adding one to an existing house can be pretty involved, and thus pricey. Now, there’s a simpler solution – a window that converts into a balcony ... of sorts.

Manufactured by Polish window company FAKRO, the Galeria balcony window is designed to be installed in a home’s sloping roof – this limits it to use in attic rooms, with a roof angle of 35 to 55 degrees.

The window is divided into an upper and lower sash. The upper sash opens upward to a 45-degree angle, locking in place and forming the roof of the balcony. The lower sash opens forward, also locking in position to become the equivalent of the balcony’s front wall. As it opens, railing-like side barriers slide out on either side – these are concealed when the window is closed.

Unlike a “real” balcony, of course, users can’t walk out onto it and sit down in a lawn chair while enjoying being completely outside. For people who are content with standing out in the fresh air or sitting half-inside, half-outside, however, it looks like an interesting idea.

There is no word on price.
