The Vessel is a Pavilion located in Iceland’s unique landscape, designed to facilitate community interaction and encourage exploration. It reflects a blend of Icelandic tradition and modern design, drawing inspiration from the geometry of Drakkar oars. The building not only serves as a functional space but also acts as a landmark that highlights the natural beauty of the surrounding environment.

Design Concept

The Pavilion is oriented along a North-South axis, creating direct visual connections to notable geological features, such as the Hverfjall Volcano, Grjótagjá lava cave, and Lake Mývatn. This careful positioning amplifies the striking views provided by the landscape. The design is meant to do more than house activities; it aims to immerse visitors in the sights and sounds of nature, inviting them to appreciate the drama of the landscape.

Access and Layout

Visitors can reach the Pavilion via a road from the main highway, which leads to an outdoor landscaped car park with space for around 50 cars and buses. A wooden pedestrian path guides people from the car park to the Main North entrance, while a slightly elevated walkway on the South side offers convenient access to the cafeteria. The layout of the Pavilion is straightforward and encourages easy movement, allowing visitors to engage with both the building and its surroundings.

Materiality and Structural Features

The design takes cues from traditional Icelandic turf houses, featuring a single inclined green roof that helps manage rainwater by reducing the load on drainage systems. The roof consists of thirteen independent troughs, allowing local vegetation to flourish and contribute to sustainable practices. Green concrete serves as the primary building material, promoting an environmentally conscious approach. Timber cladding is used for secondary elements, giving the structure a warm and inviting appearance.

Lighting and Atmosphere

Effective lighting is a vital aspect of the design, especially considering the variations in daylight throughout the year in Iceland. External light fixtures are placed thoughtfully to showcase the Pavilion’s architectural features, ensuring it remains visible from different angles. Inside, a cove lighting system highlights the timber ceiling, creating a cozy atmosphere. At night, the Pavilion becomes illuminated, with lighting that mimics the look of a lantern, harmonizing with the rich colors of the Icelandic night sky.

The Pavilion's design, particularly its green roof, allows for a smooth connection between the built environment and nature, enhancing the ecological impact of the structure. It strives to create a space where community members can gather, reflect, and engage with the landscape around them.
