Green Slab Over Concrete Walls Enhancing Visitor Engagement Amid Geological Features

Project in-detail

Concrete walls mirror the surrounding tectonic features while a green slab enhances connectivity to the landscape, functioning as an information center and visitor engagement space.
5 key facts about this project
01
Concrete walls reflect the local tectonic divide.
02
A green slab covers the first level, connecting with natural landscapes.
03
The vertical tower offers elevated views of Hverfjall volcano.
04
Integration of existing walking trails enhances visitor access.
05
Facilities include a Tower Garden and Sky Gallery for immersive experience.

The CAVE TOWER, located in Grjótagjá, Iceland, represents a thoughtful integration of architecture with the surrounding landscape. The design draws inspiration from the unique geological features of the region, particularly the tectonic divides that shape the area. This building serves as an information center and a place for visitors to engage with the local environment. With multiple levels, it offers functional spaces along with stunning views of nearby landmarks, including Hverfjall volcano and Mývatn lake.

THE NEW CRACK

The design features two concrete walls that echo the tectonic divide. These walls do more than provide structural support; they create a connection to the natural environment. They allow visitors to experience how the built structure interacts with the elements of the landscape. By reflecting the shapes and forms found in nature, the design enhances the overall understanding of the site.


THE NEW CAVE

At Level 1, a green slab covers parts of the building, resembling the entrances of nearby caves such as Karlagjá and Kvennagjá. This feature connects the design to the surrounding topography, encouraging visitors to explore the space and engage with the landscape. The use of green elements adds an attractive visual aspect while also encouraging interaction with nature.


THE CAVE TOWER

The CAVE TOWER serves as a prominent vertical feature in the landscape. It offers elevated viewpoints for visitors, allowing them to take in expansive views of the dramatic terrain. The design includes various levels, with a Tower Garden on Level 2 and a Sky Gallery located above. These elements enhance the experience, creating opportunities for different kinds of interaction with the landscape.


MATERIALITY

Materials used in the project include concrete walls, wood, aluminum plates, and glass. These materials help ensure the structure is strong while also creating a pleasing visual connection to nature. The concrete forms the main structure, while wood adds warmth and glass provides transparency. Aluminum plates offer durability and complement the modern design language.



Details such as expansive terraces and observation areas invite visitors to appreciate the surroundings, allowing them to connect with the striking geological features that define the area. CAVE TOWER blends architectural design with the natural landscape, creating a space that encourages exploration and contemplation.
