Heidegger

1. In one sense, yes. In others, no. Personal interaction can affect a building or place in our minds (individually). However, if I had an experience or interaction in a building, others have no recollection of feelings that are evoked from my personal experiences, unless they are corporate experiences. Interactions between a designer and a client will ultimately help to form a building in its most physical sense. If the client wants a bathroom, the designer helps to form a bathroom.

2.  Heidegger is definitely looking for authenticity by looking back to the Latin roots of words. It is a positive thing to look for authenticity in designing and building architecture. Architecture that is sought out with a sense of authenticity will not be misinterpreted by inhabitants as much as “false” architecture.

3. Yes, we can potentially design with this sense of permanence. It seems that the permanence that Heidegger is describing also has a sense of timelessness. In describing “death as death”, I think he is saying that we cannot change what the idea of death is at a later date. Obviously this doesn’t align with what everyone thinks, but this is what Heidegger says. I think he would say that a good architecture comes out of a sense of timelessness.
