I had never before realised what impression concrete makes on me. But in the car park of the Dahlienstrasse housing estate, I immediately felt a downward pressure in my head, especially on my forehead and above my eyes. It spread to my upper arms and throughout my full body. My chest felt tight and oppressed, and I had to really fight it.
Once I was aware of these impressions, I also registered them on the artificial stone driveway to the car park, which initially irritated me. – The tarmac road in front of the car park had a completely different effect. It seemed rubbery and soft to me, but in a weighted, unpleasant way. It went all the way up to my knees.

In the car park of the Graphis housing estate, made of pneumatite concrete, I didn’t experience the pressing and pulling down of normal concrete anywhere. On the contrary, I felt a lightness – and particularly strong in my spine – like a “pulling upwards”. This helped me to stretch inwardly, to straighten up, while my feet remained firmly on the ground. I felt generally free, in my own space. I was able to “be there” and breathe freely.
