Tensegrity Towers with Recycled Steel Above a Volcanic Chasm

Project in-detail

Utilizing tensegrity principles and recycled steel, two observatory towers rise above a volcanic chasm, offering unique vantage points for visitors to engage with Iceland's dramatic landscape.
5 key facts about this project
01
Two observatory towers utilize tensegrity construction for enhanced structural efficiency.
02
The design features vertical ascents that provide distinct visitor experiences.
03
Recycled steel is the primary material, contributing to sustainability goals.
04
Sky-walkways connect the towers, offering panoramic views of the landscape.
05
The location directly above a volcanic chasm emphasizes geological interaction.

"Deep Chasm, Deep Charm" offers a thoughtful exploration of the Icelandic landscape. Located where the North American and Eurasian tectonic plates meet, the design features two observatory towers that encourage interaction with the striking geological features. The goal is to create a space where visitors can connect with the natural environment and understand the geological processes that shape this region.

Conceptual Framework

The design focuses on the tension created by the geological activity of the tectonic plates. Each tower acts as a tool for observing the vast landscape while reflecting the forces at work beneath the surface. Visitors can experience both the immediate beauty of the environment and the broader geological stories that it tells through distinct ascent methods.

Spatial Organization

Accessing the towers is a journey in itself. One tower includes a staircase with resting areas, allowing visitors to pause and take in the views of the volcanic terrain. The second tower features a glass elevator, lifting visitors upward and creating a sense of floating above the ground. These differing experiences highlight how movement through the towers can enhance engagement with the surrounding landscape.

Structural Approach

The project uses a tensegrity structure, which combines tension and compression to create stability with minimal materials. This clever design results in a lightweight framework that appears to hover above the ground. By reducing material use, the structure maintains a delicate balance that connects it to the rugged landscape, emphasizing the relationship between the built environment and the natural world.

Materials and Sustainability

Recycled steel is the main material mentioned, indicating a commitment to sustainability. Choosing recycled materials helps to lower carbon emissions in construction. This decision supports the architectural concept while ensuring that the design is in line with environmental considerations.

Visitors can fully appreciate the depth of the chasm from the towers, as they stand open to the surroundings. The design serves not only as a viewpoint but also as a space for reflection on the powerful forces of nature that shape the world.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
