The Vogafjós Greenhouse Restaurant is located in Iceland, blending a dining space with an agricultural environment. Its design emphasizes sustainability, making local elements key features in the overall concept. The restaurant challenges traditional dining settings by positioning itself within a natural and productive landscape.

Architectural Form and Spatial Organization

The form of the Vogafjós Restaurant takes inspiration from greenhouses, using shapes that repeat while creating varied spaces. Pitched roofs are arranged in a sawtooth layout, allowing natural light to enter generously, which benefits both guests and plants. This design creates intimate areas for dining, making the experience more engaging and connected to the surrounding gardens.

Connection to the Landscape

On the exterior, the restaurant’s facade frames views of nearby baths and mountains. This connection to the landscape enhances the dining experience. Plants are cultivated under carefully controlled lighting, allowing them to thrive regardless of the weather. This adaptability is a central feature of the design, responding effectively to Iceland's climate.

Materiality and Aesthetic Integration

Rammed earth is used for the facades, giving the building a unique look. The textures and colors echo those found in the local landscape. Turf roofs are another important aspect, providing natural insulation while supporting native grasses and plants. This choice connects the restaurant even more to its environment, reducing its ecological footprint and creating harmony with nature.

User Experience and Interaction

Inside, vertical planters fill the space, creating a lively atmosphere. Guests can choose from private areas or communal tables, fostering different types of interactions. The open kitchen lets diners watch as meals are prepared, making the cooking process part of the experience. This design choice invites a sense of transparency and engagement, enhancing the atmosphere as diners enjoy their meals.

The design culminates in a carefully detailed sawtooth roof that allows sunlight to filter through and nourishes the greenery below, bringing together the elements of architecture, nature, and food.

`
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.
