Cantilevered Views Supported by Cross-Laminated Timber and Glulam in a Geological Landscape

Project in-detail

Elevated by a cantilevered structure of cross-laminated timber and glulam, the tower seamlessly integrates into its geological setting, providing an educational observation space that highlights the tectonic landscape of Iceland.
5 key facts about this project
01
Elevated observation spaces are created through cantilevered sections that extend over a geological fissure.
02
The structure utilizes cross-laminated timber panels for enhanced structural efficiency and sustainability.
03
Charred wooden shingles are employed for exterior cladding, promoting weather resistance and natural aesthetics.
04
A bent A-frame design allows for an optimal balance between stability and spatial experience.
05
The project fosters educational engagement by integrating geological information displays throughout its spaces.
The Iceland Cave Tower is an architectural project located in a unique geological setting, where the North American and Eurasian tectonic plates meet. This structure serves as a multipurpose observation tower designed to enhance visitor interaction with the surrounding landscape, while also providing educational opportunities about the geological significance of the site.

The design features a cantilevered staircase and a series of interconnected spaces that facilitate movement and exploration. The tower is constructed primarily from sustainable materials, including glulam, timber planks, and cross-laminated timber, all of which contribute to the building's aesthetic and structural integrity. The form expresses a connection to the geological context, reflecting the division between the tectonic plates in both function and appearance.

Unique Design Approaches

One significant aspect of the Iceland Cave Tower is its integration with the landscape. The building's elevations are engineered to mirror the contours of the land, ensuring minimal disruption to the natural environment. The use of cantilevered elements allows sections of the structure to extend over the fissure, creating unobstructed views of the surroundings and illustrating the tectonic activity that shapes the region. This approach emphasizes the dynamic relationship between architecture and geology.

Another aspect that sets this project apart is its focus on educational engagement. Designed to inspire curiosity about natural phenomena, the tower includes information displays and observation decks that encourage visitors to learn about tectonics, geology, and the area's ecological systems. The architectural design promotes a seamless flow of information and interaction, connecting guests to their environment in a meaningful way.

Functionality and Spatial Organization

The Iceland Cave Tower's design includes a well-considered spatial layout that caters to both individual visitors and group activities. Key components include a welcoming entrance area, a spacious waiting zone, and a café that serves refreshments. The suspended staircase not only provides access to observation platforms but also functions as a focal point within the design, drawing attention to the fissure below.

The observational areas are strategically located to offer expansive views of the landscape, maximizing the visual experience for visitors. The use of large windows and open spaces fosters a sense of connection with the surroundings, inviting guests to appreciate the natural beauty of Iceland.

For further insights into the architectural plans, sections, and overall design concepts of the Iceland Cave Tower, exploring the project presentation is recommended. Engage with the architectural designs to gain a comprehensive understanding of the intentions and innovations behind this notable project.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
