- A spotlight on a firm that has produced an impressive oeuvre over only a few yearsNikolaus Hamburger, Dario Pfammatter and Francisco Ferrandiz are the protagonists of the Zurich office HDPF. Within only a few years, the architects have produced an impressive oeuvre. The projects are mostly apartment buildings and single-family homes that are incisive in terms of their structural clarity, stringent material selection, the sculptural quality of their exterior and their pronounced tectonics. Text in German. Extra sheet with English translation included.
