Stefan Plenker's paintings, especially those of the 1980s, are characterized by an intense preoccupation with pictorial space, its construction, and the interplay between inside and outside. Interlocking walls and doors open and close glimpses into the often sparse interior. The artist's focus is less on narrative depiction; rather, his scenes are soberly described incidents of everyday reality. Plenker's interest is in the design of the surface, lines and structures. It results from a long-standing preoccupation with graphic art, through which he arrived at painting and which is also expressed in his more recent, ciphered works.
