The Vessel is an architectural pavilion located in the stunning landscape of Iceland, designed to create a shared space that encourages connection and interaction. The building draws inspiration from the shape of Drakkar oars and blends with its natural surroundings. Its position allows for strong visual connections to local features like the Hverfjall volcano and the Grjótagjá lava cave, establishing it as an important landmark in the area.

Design Concept

The Vessel is aligned along a North-South axis, which helps it highlight the geological features nearby. This orientation enhances the experience of the site and allows visitors to engage with the landscape. The building's façade includes operable louvres that manage light and ventilation. This feature is essential for maintaining comfort inside and demonstrates a commitment to environmental design.



Sustainability Features

The design includes a single sloped green roof, borrowing elements from Icelandic turf houses. This roof benefits the building’s ecological performance by improving rainwater management and allowing plant life to grow on its surface. Additionally, a system of thirteen independent roof troughs ensures good drainage, helping to minimize water runoff during heavy rainfall.



Flexible Spatial Configuration

Inside, The Vessel supports various functions, including exhibition areas, a cinema hall, and a cafeteria. These spaces are designed to work independently, allowing for a wide range of activities. This flexibility makes the Pavilion a suitable venue for community events and engagement, linking people through art and film.



Lighting Strategy

The lighting design plays a vital role in the building’s appeal. External fixtures are positioned to highlight the geometric features of the Pavilion, while cove lighting inside illuminates wooden ceilings, creating a warm and inviting ambiance. As night falls, lighting enhances the building's presence, ensuring it remains a welcoming space for visitors.

`
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.
