Stefano Riva breathes new life into ancient ruins in portugal

Vineyards cover the landscape of Resende, Portugal, where architect Stefano Riva transforms one of the site’s buildings into a holiday retreat, Casa Jeronimo. Set within the Douro region, known for its terraced granite walls and winemaking tradition, the residence emerges concerning the history of the site while introducing a bold pink volume.

One of the few surviving elements of the original structure, a weathered granite wall, encloses the residence. Rather than merely restoring the ruin, Riva introduces a contrasting concrete volume, an abstract interpretation of the historical footprint marked by the original farm building. Initially envisioned as partially subterranean, the discovery of a granite rock during construction led to the redesign of the project to respect the natural boundaries of the terrain.

climbing plants turn Casa Jeronimo’s granite wall into a garden

Italian architect Stefano Riva organizes Casa Jeronimo across two levels. The ground floor houses the kitchen and living areas, while moving up, the first floor accommodates three bedrooms and a library. Interstitial spaces between the built forms become planted voids with climbing vegetation, and trees gradually cover the structure, transforming the preserved granite wall into an enclosure for a garden.

The use of pink-pigmented concrete mirrors the regional vernacular architecture, complementing the lush greenery of the vineyards. Rather than imposing itself on the landscape, the intervention reflects a sensitive adaptation of the existing context, shaping a contemporary retreat.
