AHI Architectural Heritage Intervention

“Contributing to enhancing our heritage, as the way forward for 21 st Century architecture is our raison d’être; to emphasize a diverse, rich vision that necessarily complements the intervention is our mission, and achieving it with reflexive and purposeful efforts is the challenge”.

This project, founded in, and directed since, 2011 by Ramon Calonge, Oriol Cusidó, Marc Manzano and Jordi Portal, architects and members of the Group of Architects for the Defence and Intervention in Architectural Heritage (AADIPA), has, through the years become a platform that includes four actions that are both independent and transversal.
The European Award, a biennial event that brings together and showcases the multiple approaches of intervention in Europe.

The International Biennial, a framework that serves to compare and gain closer insight of quality interventions in architectural heritage in non-European countries.

The digital Archive, a live and open window that provides a panoramic view of interventions in the history of our surroundings.

The Forum, a meeting place where you can participate in on-going debates about the main preoccupations and lines of thought about interventions in architectural heritage in Europe.

AWARDS 6th Edition


Helsinki Olympic Stadium

Helsinki Olympic Stadium

Helsinki Olympic Stadium is a crown jewel of 1930s functionalist reinforced concrete architecture in Finland. The key objective of the project was to ensure that the conservation and revitalizing of the stadium preserves the cultural values of the heritage as well as responds to all future requirements of international sport events. In order to preserve the iconic form and respect the previous historic architectural layers of the stadium, the functions that did not easily fit the existing building frame were placed underground. The underground extension includes new multipurpose premises, sports facilities, logistical spaces, technical spaces and an indoor running track. In addition, the stadium had to undergo changes to improve public safety and comfort. New entrances to the stands and the public galleries under the structures ensure the free flow for the public during the events. A new canopy covers the stands almost entirely. The conservation respected and preserved the original 1930s and 1950s architecture.
