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.


La Carbonería

La Carbonería

La Carbonería is a highly symbolic building in Barcelona. Its rehabilitation implied dealing with diverse politics, sensibilities, history and stories. Using them carefully and intelligently has been as relevant as the attention given to its material heritage, to its structure and spaces. Built in 1864, the oldest building of Cerda’s Eixample, it had troubled beginnings. Its developer, Narcis Tarragó, was unsure if the old ‘Wall street’ would be transformed into the Boulevard that the Town Hall desired, against Cerda´s designs. Its paradoxical design reflects this uncertainty, with the facade holding the larger openings finally hidden from view. The stair and elevator were moved to the farthest corner of the patio, connecting to the façade and each individual dwelling by aerial walkways, and creating views and a three-dimensional communal space. The preexisting structure was preserved and the bearing wall was emphasized by storage and conducts areas, while openings in it connect visually the patio and the street as conceived by Cerdà.
