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.

The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction.
