I remembered this project Window 2.0 by Khoury Levit Fong. The drawing above is from their website (News: Feb 18th Window 2.0 on exhibit in the LWR Gallery.) This continues with the more abstract idea of diplomacy being applied to all architecture and in this case the simple idea of how we build transparency into our structures. In this project, a "window" can be put on any interior wall allowing those inside to look out while those outside will not know they are being seen. The idea is that an actual window may not even be needed anymore. We could build a 2' thick concrete wall and then put a screen on the interior to give the sense that there is a window to those inside when in fact there isn't any aperture at all.
We as architects have the ability to design what is seen, by who, where, and when. This gives us incredible agency in designing how business or government will interact with its constituents. Deciding what is seen and what is concealed is the most critical action in diplomacy and we as architects will be asked to design how those strategies of revelation are deployed.
