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.

Inside, the main intervention included the construction of a new vertical communication core, an evacuation staircase and an elevator adapted for people with dissabilities connecting all floors from the basement to the roof. The heritage work on the noble floor recovers the original stucco coating on the walls and ceilings in the main rooms, hidden behind several paint layers. The original glass tears lamp hanging from the ceiling of the main living room was restored and placed. Doors, windows, plinths and wood wainscoting were restored. Some doors and wood wainscoting in the corridor were reproduced mimetically, in shape and material, copying the originals stored in the MNAC. Some heritage units have been recovered, such as the “trencadís” and the glass balls of one of the roof chimneys, the movable wooden partition and the railing lamp at the end of the noble staircase, the dining room lamp, the wooden windows in the stone arches of the ground floor and the arched geometry of the false ceiling at the entrance. The façade was totally restored
