A Arquitetura Vernacular como Espaço de Intervenção. Duas obras de Eduardo Souto de Moura

Abstract

This dissertation explores the relationship between vernacular architecture and contemporaneity and proposes an analysis of intervention strategies in pre-existing vernacular structures, based on the study of case examples by the architect Eduardo Souto de Moura. It seeks to understand how it is possible to intervene in this context without compromising the vernacular identity of these buildings, while simultaneously ensuring their adaptation to the legal, functional and comfort requirements imposed by contemporary ways of life. The research begins with the definition and characterisation of vernacular architecture, highlighting its cultural, constructive and territorial relevance, and analysing how these buildings reflect communities' adaptation to their territory and to the natural resources available. It then addresses the issue of rehabilitating pre-existing vernacular structures, considering the programme-related, structural and infrastructural challenges posed by legislation, including accessibility and energy efficiency standards, which require traditional solutions to be reconsidered and adapted to contemporary demands. This reflection also extends to the impact of introducing new programmes of use, particularly tourism, which plays a significant role in rural contexts and raises specific questions regarding spatial adaptation, comfort and the functional management of building complexes. This theoretical framework provides the basis for the critical analysis of case studies that reflect distinct intervention strategies and demonstrate how the dialogue between tradition and innovation can be explored within contemporary architectural practice. Within this scope, the cases of São Lourenço do Barrocal and Quinta do Outeiro, works by Eduardo Souto de Moura, are analysed as paradigmatic examples that remain insufficiently systematised in academic literature. Although distinct in location, context and materiality, these projects share the same tourism programme and are comparatively examined through graphic elements and photographic records according to common criteria, enabling the identification of continuities, differences and intervention strategies. In these projects, critical freedoms of intervention are assumed, revealing the complexity of working with vernacular heritage and the importance of finding balanced solutions between preservation and adaptation. The relevance of this study lies in demonstrating that the constraints of vernacular architecture are not limiting but rather constitute a space for experimentation and opportunity.
