The cladding proposal for the Bon Pastor station on Barcelona´s Metro Line 9 involves the use of a single material as its conceptual language: cast stone panels with different densities, curves and perforations.
The production of the six types of panels was designed by architects Arderiu & Morató. The process combines white pre-cast stone with a gentle acid-etched finish and encrusted glass beads that let light filter through to colour the station with a dream-like blue tone. Permanent waterproofing ensures minimum maintenance under the envisaged heavy use of this station. White cast stone benches with a shiny polished finish rest on cantilevered metal brackets to camouflage the station´s air-conditioning outlets. This project was designed in 2009 by architects A&M in conjunction with Escofet.
