This modification of fence sheeting is clever because it (a) anticipates a problem, (b) recognizes human needs, and (c) responds with restraint. It’s so simple as to inspire awe: Of course people might crash into each other, of course they will want to be able to see around the corner to prevent that, and of course only one perspective matters.
This hack reminds me of forced-perspective parking garage signage. The signage is perfectly readable only when you need to read it, and disappears as soon as you no longer need it. (Axel Peemöller was the artist for the project.) In other words, instead of looking at plan and perspective drawings of our buildings, I think we should consider them in human-scale four-dimensional terms. The space should change as we move through it. This isn’t a new idea—human circulation engineers talk about altering ceiling height or lighting to subtly inform wayfinding decisions—but the level of detail in these two specific cases is incredible. There is a fineness to them, a smoothness, that comes with correctly anticipating human wants or needs. And isn’t that what we want our spaces to do?
