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 idea was designed from an inclusive perspective, to improve the quality of life of people in the neighborhood. The project tries to reconnect the different levels of the environment, building a floor with continuous paving of anti-slipping stone as an adaptation of the traditional paving system. The connections with the streets are solved with soft ramps and with stairs of small height, to facilitate the daily displacements of the elderly people. The historical Valencia Street had been lost when the archaeological area was opened up and is connected from the historical center. A large wooden platform that adapts to the natural topography with steps, recovers this historic access road. The floating plaza is a continuity of the public space of the surrounding streets, which overflies the archaeological space. A floating pavement of iroko wood slats, with details of handcrafted placement, on a steel structure that allows it to adapt to the topography. An urban space made of wood promotes the tactile sensation of small scale in urban spaces.
