Concrete buildings have something about them, I always find them cold, and I quickly feel chilly. But when I visited the hamlet of Zum Pflug in Neurheinau and walked up the concrete staircase, I was quite surprised: I felt warmth as if it were a wooden structure. The sensation was strikingly strong. Actually, everyone who passes this staircase should feel it. As it turned out, Pneumatit was used. It really takes away the coldness of the concrete – unbelievable!
