The rehabilitation project undertaken by SANTZO arquitectos involves the restoration of an old, abandoned pigsty located in a small rural hamlet within the Sierras de Cazorla, Segura y Las Villas Natural Park, in Santiago-Pontones, Jaén. Addressing contemporary housing challenges, the proposal aims to repurpose this traditional mountain building typology, highlighting local craftsmanship and trades as practices that should be preserved and passed on to future generations.

The presence of similar structures scattered throughout the region led the studio to begin an inventory and mapping of these buildings, with the goal of promoting the replication of the prototype in other abandoned pigsties, corrals, mills, or barns in the area. The intention is to establish a network of small pavilions capable of accommodating hybrid, adaptable, and flexible living arrangements.

Conceived as an experimental and sensory retreat, the project developed by SANTZO arquitectos prioritizes a close relationship with the surrounding landscape through the complete opening of its north façade, thus blurring the boundary between interior and exterior. The design is structured around three fundamental elements of the site: fire, water, and the landscape of poplars and pines.

Fire appears as a central element that seems to levitate above a platform extending between the exterior and interior, generating two distinct atmospheres linked to day and night, as well as to public and private. Water, present through an old cattle trough, functions both as a functional and environmental resource and as a support for a more intimate experience of the landscape.

From this perspective, the project understands dwelling as a flexible and diffuse act, where the same space can be transformed into a home, a workplace, or a meeting place according to the needs of its users.

Project description by SANTZO arquitectos

Located in a small hamlet within the Natural Park of the Sierras of Cazorla, Segura and Las Villas, the project transforms a derelict sty into an experimental shelter. Conceived as a prototype, it addresses the reuse of scattered rural structures while recovering the memory of vernacular architectures and disappearing crafts, engaging at once with contemporary housing concerns and the preservation of these dispersed mountain typologies.

The intervention establishes a direct and intrinsic relationship with the landscape. The complete opening of the north façade dissolves the boundary between inside and outside, allowing the surrounding environment—poplars, pines, light and atmosphere—to permeate the space. Dwelling is thus expanded through the incorporation of the sensory and immaterial qualities of the rural context. The project is articulated around three elemental figures: fire, water and landscape.

Fire becomes the gravitational centre, suspended over a platform that extends across interior and exterior, organising two complementary atmospheres: one associated with daytime and collective use, the other with night and intimacy. Water is reintroduced through a former livestock trough, reinterpreted as both a mediating device with the landscape and a functional environmental resource. Within this framework, inhabitation is understood as a fluid condition: a single, continuous space capable of accommodating domestic, productive or social uses depending on time and occupation.

In order to preserve the original longitudinal typology, an equipped steel wall is inserted along the most exposed enclosure. This element condenses the functional programme and storage, while concealing the most private areas and maintaining the spatial continuity of the nave. The intervention reveals and enhances the existing stone masonry, dating back over two centuries, as a primary material and historical substrate.

The project is grounded in reuse. Original timber elements were dismantled, catalogued and reassembled, while traditional clay roof tiles were reinstated. Existing walls were consolidated using lime mortar, and replacement timber was sourced locally, reinforcing a logic of proximity and sustainable resource management.

Craftsmanship plays a central role in the process. The project reclaims the knowledge of local trades, with all architectural elements designed to be fabricated and assembled by local carpenters and blacksmiths, both in workshop and on site. This approach responds not only to material scarcity and climatic constraints, but also to the need to preserve and transmit endangered forms of making.

The widespread presence of similar abandoned structures across the territory has prompted the development of an ongoing inventory and mapping strategy. The project thus positions itself as a replicable model, capable of being extended to other pigsties, corrals, mills or barns, reactivated as small pavilions that support a hybrid, flexible and evolving mode of inhabitation.

SANTZO Arquitectos is an architecture and landscape design studio founded in 2021 by Miguel Á. Antonio and Fran Sánchez, both graduates of the Higher Technical School of Architecture of Seville and holders of a Master's degree in Architecture from the University of Seville.

Based in Baeza (Jaén) and Seville, SANTZO Arquitectos develops projects that balance reality and abstraction, actively collaborating with traditional craftsmanship in their respective spaces. Their primary focus is conceptualizing projects in relation to their territory, landscape, and unique historical heritage, seamlessly integrating rural and urban environments, and highlighting the authenticity of cultural heritage through contemporary inhabitation. Their projects have been finalists in the New European Bauhaus competition and have received the Richard H. Driehaus International Architecture Award.

Fran Sánchez Salazar graduated as an architect from the Higher Technical School of Architecture of Seville in 2021, achieving the highest academic standing in his graduating class and receiving both the Extraordinary End-of-Studies Award and the Royal Cavalry Armory Award. Fran completed his fourth year at the Technical University of Munich (TUM) and received First Prize for his Final Degree Project. In 2019, he was awarded an Arquia Grant for an architecture internship at Kéré Architecture in Berlin, as well as First Prize in the 2020 Pladur competition.

Miguel Ángel Antonio García graduated as an architect from the Seville School of Architecture in 2021, ranking second in his class. He received First Prize for his Final Degree Project and an Honorable Mention for his Final Year Project. In 2020, Miguel Ángel received a research and study grant at the University of Pennsylvania and was awarded an Arquia Grant that same year for an internship at the Ministry of Housing (MITMA). In 2018 and 2022, he won First Prize for ARPA projects on Cultural Heritage.
