Hyperboloid Structure Featuring Translucent Roofing and Rainwater Harvesting in a Volcanic Landscape

Project in-detail

A rotating hyperboloid structure integrates transparent ETFE roofing and rainwater harvesting systems, creating a visitor center that harmonizes with Iceland's volcanic landscape while emphasizing sustainability and accessibility.
5 key facts about this project
01
A rotating hyperboloid shape optimizes energy efficiency and wind resistance.
02
The ETFE roofing allows for natural lighting while reducing structural weight.
03
Rainwater harvesting systems contribute to sustainability and resource management.
04
Accessible design features a gentle ramp for ease of movement throughout the space.
05
The integration of local materials enhances environmental compatibility and aesthetic cohesion.
The VOLCANO project, designed as the Iceland Cave Tower, integrates architectural form with the geological features of Iceland's volcanic landscape. This structure serves both a functional and educational purpose as a visitor center, allowing occupants to engage with the environment while highlighting the significance of Iceland's geological formations.

The architecture of VOLCANO embodies a unique narrative directly connected to the surrounding natural world. Its design features three key components: a spiral walkway, a conical structure, and a rotating hyperboloid. The spiral walkway ascends gracefully, guiding visitors through a sensory experience of sight and sound, while providing panoramic views of the landscape. The conical structure houses essential amenities, including a café, offices, and restrooms, designed with accessibility in mind. This ensures that all visitors, regardless of mobility challenges, can enjoy the space.

The rotating hyperboloid acts as a reservoir for sustainable energy, symbolizing the natural energy sources inherent to the region. It integrates practical applications, including rainwater collection and natural heating systems, enhancing the structure's overall efficiency and environmental integrity.

Unique Design Approaches

A pivotal aspect of this project lies in its innovative use of materials and forms. The utilization of steel beams, coated with matte dark red paint, provides structural stability while harmonizing with the natural surroundings. Reinforced concrete piles are strategically placed to minimize disruption to the ecosystem. The ETFE membrane, employed for the roof, not only allows for natural light but also creates a dynamic interaction with the climatic conditions in Iceland. This transparency is essential for fostering a connection between visitors and the striking landscape.

The flooring of the walkways incorporates grating to facilitate drainage, effectively addressing the climatic challenges posed by Iceland's wet conditions. This practical consideration enhances user safety and maintains the functionality of the structure without compromising its aesthetic value.

Sustainability is a core design principle in the VOLCANO project. By integrating rainwater harvesting, energy-efficient systems, and natural materials, the project minimizes its environmental footprint while promoting awareness of sustainable practices among visitors.

Exploring the architectural plans, sections, designs, and ideas presented within the VOLCANO project may provide deeper insights into the thoughtful design strategies employed. A closer examination reveals how architecture can reflect and respect the natural world, offering a valuable experience for those who visit this unique structure. The architecture of VOLCANO serves as an example of how design and nature can coexist, creating spaces that educate and inspire.

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.
