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.


Parliament of Canton Vaud

Parliament of Canton Vaud

The Parliament of Lausanne, built by Alexandre Perregaux in 1803 was destroyed by a fire in 2002. Its reconstruction presented the opportunity to reassess the criteria that would allow solving both the parliamentary seat and the revitalization of the neighboring buildings. The project proposed an architecture capable of restoring the continuity and atmosphere of the historical city, the synthesis between old and new. From afar, the new Parliament becomes the puzzle piece that completes the historical site of la Colline de la Cité. Its strategic position between the Cathedral, rebuilt by Viollet-le-Duc, and the Saint-Maire Castle provides a setting that rebalances the presence of the religious and military institutions. The three-story-high foyer unites and separates the diverse spaces, it is a place of encounter. Three elements qualify it: the singular staircase; the presence of the historical façade of Maison Charbon, one of the oldest façades of the city; and the new access, crossing it means entering into a particular atmosphere.
