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.


De Meelfabriek

De Meelfabriek

Located in the center of Leiden in the Netherlands, De Meelfabriek is a major redevelopment project (55,000 sqm) of a former industrial flour mill complex composed of ten historically listed buildings, and 4 new buildings. After being acquired by a private developer in 1998, a zoning plan was originally commissioned to Peter Zumthor Atelier in 2002. Studio Akkerhuis was hired in 2015-2016 to redevelop the masterplan and continue the project. Today, the masterplan strives to reconnect the historic site with its surroundings, creating a new mixed use urban neighborhood. This is achieved through circulation and visual axes drawn across the site, these connect the city to the canal and the adjacent municipal green spaces. The Meelfabriek complex is made up of buildings with diverse architectural features, materials and details that reflect their industrial past. The refurbishment of these buildings focuses on those emblematic features creating a new neighborhood with a startling diversity of urban and architectural spaces.
