Transparent Steel Structure Mimicking Natural Caves For Elevated Geo-Tourism Experience

Project in-detail

Combining transparent steel sheets with a design that echoes the region's natural caves, the observation tower elevates visitor engagement with the geothermal landscape of Vogar while serving as a comprehensive viewpoint and visitor center.
5 key facts about this project
01
The tower's design incorporates transparent steel sheets to create an immersive connection with the landscape.
02
Multiple observation decks are strategically placed to enhance the viewing experience of the geothermal features.
03
Sustainable energy solutions include a wind turbine and solar panels integrated into the service building.
04
The structure's form reflects the geological history of the region's tectonic plates.
05
Interior spaces are designed to echo the organic shapes found in natural caves, fostering exploration.
The Grjótgjá Observation Tower, located in Vogar, Iceland, is an architectural intervention designed to enhance visitor engagement with the surrounding geothermal landscape. Its purpose is to serve as a viewing platform and visitor center, allowing individuals to experience the unique geological features of the site, particularly the nearby geothermal hot spring caves known as Karlagjá and Kvennagjá. The project reflects a commitment to integrating architecture with the natural environment while providing educational opportunities regarding the region's geological history.

The tower’s structure, rising to 22 meters, features a slender design that mimics the natural forms of the Icelandic landscape. The adjacent service building, which accommodates a café, visitor facilities, and storage space, measures 13 meters in height and shares design elements with the tower, ensuring visual cohesion. The materials used in construction include standard steel for the structural elements and extended steel sheets for the exterior surfaces. These choices allow for transparency and light filtration within the space, creating a visually engaging experience for visitors.

The Observational Experience

One of the unique aspects of the Grjótgjá Observation Tower is its multi-level observation platforms. These platforms are strategically placed at various heights, providing a tiered approach to viewing the geological landscape. This design encourages visitors to ascend gradually, with resting areas that invite reflection and interaction with the panoramic vistas. The internal configuration includes a stairway with multiple landings, echoing the experience of traversing through natural caves, and reinforcing the connection between architecture and geology.

Sustainable Design Features

The project incorporates several sustainable design elements, including solar panels and a wind turbine positioned atop the service building. These features are essential for meeting the energy needs of the structure while reducing its environmental footprint. The careful selection of materials not only enhances aesthetic appeal but also contributes to the overall sustainability of the project. The semi-transparent steel sheets used in the exterior create visual links to the dynamic environment, allowing visitors to feel connected to the surrounding landscape as they explore the tower.
