Perforated Facade of Black Aluminum Foam Framing Expansive Views in a Volcano Landscape

Project in-detail

A porous facade of black aluminum foam interacts with the volcanic landscape, seamlessly blending indoor and outdoor experiences in a museum dedicated to cultural exploration.
5 key facts about this project
01
Black aluminum foam facade mimics solidified lava.
02
Porous wall design filters views and enhances user interaction.
03
Cafeteria includes continuous window bands for panoramic landscape views.
04
Flexible exhibition space allows for varied display arrangements.
05
Site integration utilizes the natural topography for visitor experience.

HRAUN STRAUMUR, meaning "Lava Stream," is situated in Iceland, a country known for its dramatic geological features, including volcanoes and rugged landscapes. The design integrates the building with the gentle slope of the terrain, creating a low-lying oblong structure that protects visitors from strong winds. It provides a clear distinction between the functional northern side and the picturesque views to the south.

Conceptual Framework

The design focuses on the visitor's journey. Upon arrival, guests transition from vehicles to a covered walkway. This walkway features a wall that mimics solidified lava, creating a unique interaction with the landscape. As visitors walk along this path, they experience filtered views, adding a sense of curiosity and connection to their surroundings.

Spatial Organization

The layout consists of a single level, which simplifies the arrangement of various spaces, such as exhibition rooms, a cafeteria, and offices. Smaller rooms are located towards the north for efficiency, while larger, flexible spaces face south and west to take advantage of natural light. This configuration supports various functions and enhances the overall visitor experience.

Material Palette

The project uses black stabilized aluminum foam known as "Alusion" as its main exterior material. This lightweight material resembles lava's appearance, reinforcing the connection between the building and the local geology. Additionally, basalt floor tiles are integrated into the interior spaces, ensuring a consistent visual theme throughout the museum.

Design Detailing

A notable feature is the cafeteria, which extends outward and includes large window bands. This design invites visitors to view the surrounding landscape while they eat and relax. The openness blurs the line between inside and outside, fostering a closer relationship with the natural environment.
