5 key facts about this project
01

02
Incorporates basalt rock to enhance natural insulation for indoor agriculture.

KVIKA is an innovative project that combines a restaurant with a greenhouse, located in the distinct climate of Iceland. The design focuses on promoting sustainable practices by integrating food cultivation directly into the dining experience. This approach allows diners to enjoy fresh produce while engaging with the process of its growth, highlighting the connection between nature and food.

Design Strategy

The project employs bioclimatic principles, aimed at optimizing the building's performance in a challenging environment. With temperatures averaging -0.5°C, careful consideration has been given to orientation and thermal control. Features such as large windows and natural ventilation enhance airflow and sunlight penetration, creating a comfortable atmosphere for both the greenhouse and restaurant areas.

Material Selection

Reinforced concrete is used for the walls and slabs, providing a solid structure that can withstand the harsh Icelandic weather. This choice is not only practical but also contributes to the longevity of the building. Alongside concrete, basaltic rock plays an important role in insulation and stability, helping to regulate temperatures throughout the year.

Landscape and Outdoor Engagement

A significant aspect of KVIKA is its roof garden, which elevates the overall experience. This green space adds beauty to the structure and serves as a habitat for local wildlife. It also acts as an outdoor dining area, allowing guests to connect with the surroundings while enjoying their meals. The design emphasizes a relationship between the built and natural environments, enhancing the sense of place.

Sustainability Integration

Throughout the project, a strong emphasis is placed on sustainability. By integrating agricultural practices into the urban landscape, the design serves as a practical example of how to combine food production with dining. The thoughtful arrangement of spaces allows for a direct experience of both cultivation and consumption. Above the restaurant, the roof garden provides a refreshing touch of greenery, bridging the gap between nature and the dining table.

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.
