Geothermal Observation Tower Crafted From Recycled Aluminum Foam and Steel Grating

Project in-detail

Built from recycled aluminum foam and galvanized steel, the geothermal observation tower reflects the geological fissures of Myvatn, offering a unique vantage point for visitors to engage with the surrounding volcanic landscape.
5 key facts about this project
01
Constructed using recycled aluminum foam, the tower offers enhanced insulation and reduced environmental impact.
02
The design mimics geological fissures, creating a direct connection between architecture and landscape.
03
Galvanized steel pathways provide structural support while maintaining minimal visual disruption.
04
The observation platform is strategically positioned for panoramic views of the volcanic terrain.
05
Underground facilities are discreetly integrated, promoting a focus on the natural surroundings.
The Iceland Cave Tower, also referred to as "Twower," is an architectural project situated at Myvatn, Iceland, a landscape characterized by volcanic activity and tectonic features. The design serves as an observation structure that integrates with its environment while providing a point of interest for visitors. It draws upon the geographical context, connecting the concepts of nature's dynamic processes with a functional architectural form.

The main components of the tower include a prominent vertical structure and lower facilities that cater to visitors. The tower is designed from recycled aluminum foam, providing a durable yet adaptive facade that echoes the terrain's colors and textures. Surrounding pathways made of galvanized steel grating allow for visitor access while ensuring minimal visual impact on the landscape. Below ground, facilities such as a café and exhibition space offer educational opportunities while remaining unobtrusive.

Unifying Form and Function

The Twower represents a blend of contemporary design and ecological sensitivity. Its tall, geometric form symbolizes the rifts created by tectonic movement, which serves a dual purpose: it acts as an iconic landmark while mirroring the geological features of the region. The design approach emphasizes transparency and connection with the environment, as the steel pathways facilitate airflow and maintain visual continuity between the tower and surrounding landscapes.

In addition, the materials selected for the project speak to sustainability and long-term durability. The use of recycled materials not only reinforces a commitment to eco-friendly practices but also promotes resilience against Iceland's variable weather conditions.

Integration with Landscape

Carefully positioned to enhance site visibility without dominating the horizon, the Twower is oriented for optimal views of the Myvatn area. This location reinforces the architectural relationship with the landscape, encouraging visitors to engage with the surrounding natural beauty. The design also accommodates the harsh weather, ensuring the structure remains functional and safe.

The underground facilities offer essential visitor services, maintaining focus on the tower itself and minimizing disruption to the terrain. This design strategy aligns with contemporary architectural ideas that prioritize harmony between built and natural environments.

The Iceland Cave Tower serves as a significant architectural statement in a unique geographical context. Through the innovative use of materials and a thoughtful design approach, it illustrates how architecture can complement and reflect its surroundings.

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.
