With help of Lioydwerft, Rot Treppe was finished in October 2005, which means a perfect end of my study in Germany. I applied parallelogram theory in this stair design that leaves out of traditional handrail and full of resilience. It was awarded as creative design in competition held by Germany Steel Association in 2006, and also reported on Core 77 in July 2007 and appears more on different design website after that. Recently I found it appears on 2 Czech architects’ website that was applied in their interior design.
