The illuminated display at the front door belongs to the alarm system. By the way, today we think that was our most unnecessary and also an expensive investment. Somehow we let ourselves be persuaded. We have attentive neighbors, patients from the practice across the street always glance over, we live in an inconspicuous side street in an inconspicuous town. I find the alarm system very cumbersome and I don’t feel like always programming my way through it. Most of all, I fear the hellish siren going off because I make a mistake or accidentally open a window. And on vacation, you first have to give the neighbors or children a course in how to operate the alarm system for watering the plants. Oh no...
The hallway is 2 meters wide, as already well calculated here
