Bloomframe, a window that turns into a balcony, was widely covered last month for making many an urbanite's dream come true. Designed by Amsterdam architect duo Hofman Dujardin, the prototype window frame opens with the push of a button.

Other than the dirt problems posed by using a floor as a wall, the inconvenience of having to set up (and store) furniture and structural safety concerns, the Bloomframe is a clever device addressing the most tricky of design problems: space. It also adds an aspect of seasonal design to the facade of a building; "where in the winter the facade is closed, during the spring the building opens itself like a flower." Look for it in production later this year.
