The Monte D'Oiro Wine Tasting Room is situated in the Lisbon Wine Region of Portugal, designed to serve as a welcoming space for wine tasting while reflecting the essence of its natural surroundings. The concept derives from its name, “Hill of Gold,” aligning modern design approaches with traditional Portuguese characteristics. The structure engages with the land, allowing visitors to appreciate both the building and its picturesque context.

Spatial Layout

The design consists of three distinct levels, each aimed at enhancing the visitor experience. The lower floor offers flexible spaces, suitable for varying functions. On the ground floor, the wine tasting room takes center stage, accommodating around 30 guests. A semi-formal lounge provides additional seating, promoting interaction and enjoyment of the wine produced on-site.

Natural Interaction

A key feature is the elevation of the building above a sunken koi pond. This pond is not only a calming visual element but also serves to regulate the temperature within the tasting room. The design incorporates cross ventilation, which helps counteract the challenges posed by the local climate, such as high temperatures and strong winds throughout the year.

Focus on Sustainability

Sustainability plays an important role in the design. The grass roof reduces solar heat gain and enhances thermal efficiency within the building. This feature is in line with modern ecological practices, ensuring that the structure operates in harmony with its environment. The presence of the koi pond further contributes to sustainable design by fostering a connection between the natural and built settings.

Interior Experience

Inside, the aesthetic combines timber and concrete, establishing a tactile relationship with wine barrels and the surrounding stone elements. Visitors approach the tasting room via floating concrete steps, which provide a connection to expansive views of the landscape. The design includes limited window openings and strategic placements to enrich natural light within the tasting spaces, creating a warm and pleasant atmosphere.

The careful arrangement of materials and the alignment of spaces create an engaging environment for guests. It allows them to enjoy not only the offerings of the vineyard but also the beautiful views that stretch across the property.

`
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.
