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.

The restoration philosophy implemented by the Ma2 Office aims to rediscover a lost heritage, the objective is to return to the Pristine state. Despite the little graphic documentation on the original project, preliminary studies (historical, stratigraphy, archaeological and pathological) have enabled to discover plenty of traces of the original scenery and thus reconstruct them, almost in their entirety. Where the vestiges were too incomplete, a clearly identifiable interpretation is implemented. After a study of three years, the recent restoration has been the subject of two years of construction work. We find today a complete work, where the original identity of the architect Gustave Strauven was re-insufflated by the precious work of workers and craftsmen at the service of the architectural heritage.
