Adif AV has pre selected the design proposal submitted by UNStudio, with b720 Arquitectura and engineering firm Esteyco, to be the winning proposal for the remodelling of Madrid-Chamartín Clara Campoamor and its urban integration. ‘Open Ecosystem’ unanimously obtained the maximum possible score from the jury in an international competition to transform the Madrid-Chamartín Clara Campoamor railway hub into an international benchmark for sustainable, multimodal, connected and integrated mobility. A key element that UNStudio, b720 Arquitectura and Esteyco team deemed essential in the proposed design was to retain and respect the historical vaulted roofs of Chamartín station, recognising them as a singular and identifying element of the station. Stepped terraces are also added to generate permeability with the surrounding city, while urban balconies open views over the station and integrate the complex into its surroundings. As such, the station forms a porous extension to the new parks located on either side of the complex. Other shortlisted teams included BIG, Foster + Partners, OMA, Zaha Hadid Architects, Grimshaw, RSHP and Souto de Moura. The design for the Madrid-Chamartín Clara Campoamor masterplan builds on UNStudio’s 30 years of experience and accumulated expertise in station design. From Arnhem Central Station to the Doha Metro Network, UNStudio has consistently put design excellence, urban activation, sustainability and outstanding user experience at the forefront of its mobility projects.
