On Monday Cressida at the St Pancras Station Champagne Bar told us all to make a Johari window for the building around us. The Johari window was devised in 1955 by Joe Luft and Harry Ingham to illustrate human relationships in terms of known knowns, known unknowns, unknown knowns and unknown unknowns. It’s made up of four quandrants described below, with Cressida’s versions in brackets.

Quadrant I, the area of free activity, refers to behaviour and motivation known to self and known to others.” (Things both St Pancras Station and other people know about the station)

Quadrant II, the blind area, where others can see things in ourselves of which we are unaware.” (Things other people know about the station which the station itself doesn’t know.)

Quadrant III, the avoided or hidden area, represents things we know but do not reveal to others.” (Things St Pancras Station knows about itself but other people don’t.)

Quadrant IV, the area of unknown activity. Neither the individual nor others are aware of certain behaviours or motives. Yet we can assume their existence because eventually soem of these things become known, and it is then realized that these unknown behaviours and motives were influencing relationships all along.” (Things neither St Pancras Station nor other people know about the station.)

Here are mine.


I wonder what a building knows and doesn’t know, and whether it’s determined by what’s visible anywhere within its walls, or by the scope of its CCTV cameras, or by the reasonable projections of its engineers and architects beforehand, or by minute fluctuations (I visit, I breathe, a cat thinks, a watch runs out of battery, I blink, I leave) that cause changes the fabric of the building and the particles it contains.
