After World War II his artistic career led him to Hans Scharoun. Ruegenberg preferred the architecture of the «sensual, dynamic Scharoun» in comparison to the work of the «crystal clear, intellectual Mies». In Ruegenberg's mind the conceptional process was identical to a sculptural task, by creating inhabitable constructional sculptures, tailoring them for needs of humans.
End of the 1980s, a close cooperation between Sergius Ruegenberg and Axel Bruchhäuser resulted in sketches and drafts for TECTA and a cantilever chair called «Tugendhafter Sessel» - tugendhaft implying the chair's antecessors, directly meaning virtuous. «The secret is the suspension» Ruegenberg wrote. Finally in 2006, as a result of this coopeartion, the 'tugendhaft' Ruegenberg-Chair was realized.
