Reviving Heritage: Cas’Amaro by Atelier Central Arquitectos

Cas’Amaro, perched above Aldeia Galega da Merceana, exemplifies heritage and modernity coexisting in harmony. Atelier Central Arquitectos transformed this once-ruined winery into a luxurious living space focused on wine tourism. 

Restoring the Winery

The old winery retains its original charm and now serves as a grand social space with reception, living, and dining areas. Behind the iconic concrete wine vats are a hidden kitchen and bathroom. Large facade openings, protected by pine shutters, allow light to flood in while offering stunning vineyard views. An exterior insulation system preserves the building’s historic appearance while providing thermal comfort.

New Living Quarters

The new living quarters are subtly integrated into the landscape, half-buried to minimize the impact on the original structure. Designed as a gray stone block, these spaces include deep window recesses for intimate vineyard views, recessed balconies for privacy, and a rooftop infinity pool that reflects the panoramic landscape.

The Role of OTIIMA's Windows

OTIIMA’s minimalist window systems, specifically the Plus 38 and Pivot 38, are central to the project’s success. These systems are instrumental in creating a seamless connection between the interior and exterior spaces, framing the picturesque views of the vineyard while maintaining thermal efficiency and aesthetic coherence. The large, unobstructed glass panels enhance the sense of openness and bring the beauty of the surrounding landscape into the living spaces.

Enhancing the Landscape

The project’s focal point is the vineyard’s dynamic landscape. The access road remains unchanged but is reinforced for all-weather vehicle traffic. A discreetly positioned parking area is hidden by vegetation and blends seamlessly into the natural environment. A shaded barbecue area, framed by a steel structure to support vine growth, is perfect for social gatherings and wine tastings.
