Cantilevered Steel Observation Tower With Volcanic Rock Integration Over Geothermal Fault Line

Project in-detail

Rising above a geothermal fault line, the cantilevered steel observation tower seamlessly integrates volcanic rock and glass to provide a multifunctional space for visitors to engage with Iceland’s unique geological landscape.
5 key facts about this project
01
The structure is cantilevered to provide unobstructed views over the fault line.
02
Integration of local volcanic rock enhances the building's environmental context.
03
Large glass panels allow natural light while maintaining structural integrity.
04
The design features interactive pathways that guide visitor exploration.
05
Community spaces encourage social engagement and education about geology.
The architectural design project "In Between" is located in Iceland, positioned at a notable fault line that exemplifies a blend of natural and man-made environments. This tower structure serves multiple functions, notably as an observation point and a public space that enhances visitor engagement with the surrounding landscape. The design reflects an exploration of geological processes while providing a unique visitor experience that is both educational and immersive.

Structural Innovation and Material Use

The architectural form of the project is defined by its towering presence, which resembles an elongated gateway. This shape not only serves as a visual marker of the fault line but also facilitates the flow of visitors through various levels. The design incorporates steel as the primary structural material, ensuring stability while allowing for expansive spaces. Large glass panels are utilized in the observation platforms, providing unobstructed views of Iceland’s dramatic landscapes. The choice of volcanic rock as a material reinforces the connection to the site, creating both aesthetic and contextual relevance. Wood is employed in certain internal areas, including rest spots and cafés, to foster warmth and comfort in contrast to the steel and glass components.

Pathways and User Experience

A significant aspect of the design is the pathway system that connects different elements of the project. These pathways lead visitors through the varying spatial dimensions, encouraging exploration and interaction with the architecture as well as the landscape. The tiered observation areas allow for panoramic views, aligning with the concept of traversing the fault line. This experience is further enriched by dynamic viewpoints, which change with the visitor's movement within the space. The integration of public spaces is another focal point, as communal areas for information and relaxation are woven into the fabric of the design, enhancing social interaction.

Engagement with Geography

The architectural design meticulously responds to the geographical context of its location in the Icelandic landscape. By articulating the concept of the fault through structural elements, the project embodies the natural processes that shape the land. The careful consideration of material choices, including locally-sourced volcanic rock, further solidifies the building’s relationship with its environment. The result is a structure that stands not only as an observation point but as a platform for education and understanding of geological features.

For a comprehensive exploration of the "In Between" project, including detailed architectural plans, sections, and design ideas, readers are encouraged to delve deeper into the presentation of the project. This examination will provide valuable insights into the unique architectural approach and the elements that make this project distinct within the broader context of contemporary architecture.

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.
