Adif AV has announced the winning design proposal submitted by UNStudio and b720 Arquitectura and engineering firm Esteyco for Madrid-Chamartín Clara Campoamor railway hub in Spain.

In 2020, Adif AV launched the global competition for transforming the railway hub into an international benchmark for multimodal, connected and sustainable integrated mobility.

A jury comprising 16 members unanimously gave the maximum score for the design proposal by UNStudio, b720 Arquitectura and Esteyco.

The jury considered various design aspects to transform the complex into an urban reference.

UNStudio founder and principal architect Ben van Berkel said: “We are truly delighted that our design has been nominated as the winning proposal for this extremely exciting urban regeneration project.

“Madrid is fast becoming one of the most exciting and attractive cities in Europe. The transformation of this area will invigorate this part of the city while adding new green lungs to Madrid.”

UNStudio, b720 Arquitectura and Esteyco considered retaining and respecting the historical vaulted roofs of Chamartín station in the proposed design.

They recognised them as a singular and identifying element of the railway hub.

Additionally, the proposal includes stepped terraces added to generate permeability with the surrounding city.

The station forms a porous extension to the new parks on either side of the complex.

It is flanked by new towers and fronted by a public square.

Foster + Partners, BIG, OMA, Grimshaw, Zaha Hadid Architects, RSHP and Souto de Moura are the other teams shortlisted in the competition.
