Focusing on the agricultural area of “Capo Due Rami” in Rome, this research aims to interpret the architectural features of the rural dwellings through a typological analysis. Drawing on data collected from direct surveys, historical records, cartographic materials, and documentary sources, the morphological and settlement evaluation of agricultural constructions refines traditional methods and techniques used in the analysis of residential models. Using specifically designed observation sheets, the study highlights how the reclamation and drainage works carried out predominantly between the 19th and 20th centuries in the area have influenced the typology of buildings and their relationship with the agricultural environment. The findings underscore that the morphotype of the dwellings in “Capo Due Rami” derives from the practical demands of agriculture and the functional requirements of rural life, incorporating targeted architectural solutions to address sanitary and environmental concerns. The observation sheets were designed to integrate qualitative indicators, drawing on previous investigative experiences in typological analysis. While adhering to established methodologies, they have been modified to reflect the cartographic and documentary data specific to “Capo Due Rami”. This approach has made it possible to highlight the distinctive features of the area, such as the proximity between buildings and reclamation canals.

Through a systematic review of sustainable rural dwelling recovery, this study offers a broader reflection on retrofitting practices, viewing eco-efficiency as a means to enhance both cultural heritage and agricultural landscapes. The work is based on the assumption that vernacular architecture in rural contexts embodies historical, cultural, and typological values worthy of preservation, while remaining adaptable to reuse through eco-efficient solutions and technological innovation. Using the PRISMA protocol, 115 scientific contributions were selected from 1711 initial records and classified into four macro-groups: landscape relationships; seismic and energy retrofitting; construction techniques and innovative materials; and morphological–typological analysis. Results show a predominance (over 50%) of passive design strategies, compatible materials, and low-impact techniques, while active systems are applied more selectively to protect cultural integrity. The study identifies replicable methodological models combining sustainability, cultural continuity, and functional adaptation, offering recommendations for future operational guidelines. Conscious eco-efficient retrofitting thus emerges as a strategic tool for the integrated valorization of rural landscapes and heritage.

This study builds on a previously developed typo-morphological method used for the rural architecture of the “Capo Due Rami” area and tests its transferability to the northern sector of Sabaudia within the Pontine reclamation system. Beyond the historical, typological, and landscape dimensions explored earlier, this research adds a further analytical component focused on the relationship between settlement form and territorial planning. This extension represents the major methodological contribution of the study, allowing the repetitive structure of Opera Nazionale Combattenti farm units to be interpreted not only as a building system but also as an implicit territorial-planning device. The case study, located in the northern sector of Sabaudia, explores the relationships between the colonial settlements of the Opera Nazionale Combattenti (ONC), the agrarian framework, and the reclamation infrastructures, interpreting the repetition of settlement models as an implicit form of territorial planning. Using an integrated framework based on field surveys, archival materials, and multiscale cartographic analyses, the observation sheets show how architectural features, land-division schemes, and reclamation infrastructures are structurally interrelated. The results show that this new analytical dimension enhances the method’s interpretative capacity, highlighting the role of typological standardization in shaping the spatial and cultural structure of the reclaimed landscape. They reveal the morphological and functional consistency between architecture and landscape. Overall, the investigation confirms the coherence and replicability of the expanded approach. It shows that rural architecture is not only the material expression of a productive model but also an active agent in constructing and regulating the Pontine agrarian territory. Rural building emerges not only as the material outcome of a productive model but also as an active agent in shaping the agrarian territory. The research helps establish a comparative framework for interpreting Italian rural landscapes, supporting the valorization of vernacular heritage and reflection on the implicit planning principles embedded in typological architecture.
