5 key facts about this project

05
The layout promotes an engaging flow between indoor and outdoor spaces.

The Monte d'Oiro Wine Tasting Room is located in Alenquer, a region in Portugal known for its rich agricultural landscape and grape cultivation. Serving not just as a place for wine tasting, the design integrates with the surrounding vineyard, enhancing visitors' connection to the winemaking process. The building is thoughtfully placed into the hillside, allowing for spectacular views while respecting the natural terrain.

Architectural Concept

The design emphasizes a strong relationship between the tasting room and the vineyard. By lowering the building, it creates visual access to the expansive fields of grapes. A ramp provides an accessible path that invites visitors to engage with the landscape. Large glass walls allow ample natural light to enter the space, creating a feeling of openness and welcoming guests to experience the beauty of the vineyard directly.

Interior Layout

Inside the tasting room, the layout is designed to enhance the experience of wine tasting. Upon entering, guests encounter a sliding door that opens smoothly, creating a clear passage into the main area. The arrangement emphasizes views of the vineyards, promoting a bond with the scenery. A notable feature is the suspended table, which accommodates up to thirty individuals. This element not only serves a practical purpose but also enhances the room's flow, making it an inviting place for social gatherings.

Materiality and Detail

Materials selected for the tasting room play an essential role in defining the space. The design includes glass, wood structures, wood ceilings, stone backwalls, cement-based concrete, and concrete floors. These choices provide a sense of warmth and connection to the natural surroundings. The use of timber columns and wooden beams adds durability, while the white textured cement walls reflect a balance of modern and traditional Portuguese styles.

The south-west wall consists of glazed sections with retractable doors that create a clear link between indoor and outdoor areas. This design detail promotes interaction with the vineyard outside and allows natural light to shape the atmosphere throughout the day. As the light changes, it adds subtle variations to the tasting experience, enhancing the overall environment for guests.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
