An old favorite of mine is this window (picture taken september 2007, Bernoulliborg - Groningen, NL), it is just impossible to use! :) Although the big window looks fancy, it is impossible to walk through the corridor if it is opened! The window has no ‘half-open’ position, it is either open or not. Nor has it got hinges to support rotating it over an other axis… Another oddity is that behind this window is not the outside world, but rather another layer of glass with blue dots on it.
Solution 🔗
Please allow the window to be opened by rotating it on the bottom axis and have it not open all the way!
