Construire à distance : les réalisations de l'agence immobilière genevoise Addor et Julliard à Beyrouth dans les années 1950-1960

Through a case study, this research aims at contributing to the historic understanding of the international architecture after the Second World War. It is based on the monographic analysis of the projects realised by the Geneva agency Addor & Julliard in Lebanon during the years 1950 to 1960. The general theme of "constructing at distance" embraces and problematizes two types of considerations: on the one hand, the challenges that international architecture of the years 1950-1960 had to face when the operations of conception and execution where realised in different contexts (i.e. functional and technical challenges due to climatic imperatives; logistical challenges linked to the characteristics of the local culture of construction ; strategic challenges in relation to the specific political and economic situation in the developing countries) ; on the other hand, the specific creative opportunities that the internationally active agencies were able to seize abroad and of which also their local production took advantage (treatment of prestige programs and ambitious operations with partners open to avant-garde experimentations). The operations realised at distance by the Geneva agency Addor & Julliard in Lebanon constitute an architectural corpus of approximately ten buildings in the urban and suburban zone. These realisations, which are not well known in the circles of researchers and architects, both locally and internationally, deserve to be analysed in detail, as they are very representative for the atmosphere of experimentation during the years 1950-1960 in Lebanon and generally in the other contexts of north-south collaboration. The work of the agency Addor & Julliard is still not well known in Geneva, with the exception of some publications on important projects like the Cayla campaign, or the Budé and Lignon blocks. Especially, the importance of the profitable interactions that the agency was able to establish between its two fields of activities in Geneva and Lebanon, and its significance for the development of this big agency, have not been stressed enough. The introductory part of our work situates the actuality of the problematic, in relation to the specific stakes of the protection of architectural and urban heritage in Lebanon. Still today, the heritage of the 1950-1960's is insufficiently understood in its cultural significance. It is also very much threatened. When it is not destroyed, it suffers from a camouflage that makes it totally unrecognisable. We then present the abundant documentation that we have gathered. This work on source material is necessary to counteract the superficial prejudice with which this architectural corpus is confronted. This part is then followed by a historical chapter on the agency Addor & Julliard before the opening of its Lebanese branch, as well as an overview of the Lebanese context between the beginning of the XXth century and 1960. These elements allow us to assert that the decisive factor allowin
