Bridging Geological Cracks With Reinforced Concrete and Modular Pathways

Project in-detail

An elongated structure of reinforced concrete spans a geological crack, integrating a modular pathway system that connects private and public cave environments, serving as an inviting visitor center in Iceland's unique landscape.
5 key facts about this project
01
An elongated form allows for panoramic views of the surrounding Icelandic landscape.
02
The modular pathway system is inspired by the flexibility of the human spine.
03
Uses reinforced concrete to navigate the geological challenges of the site.
04
Distinct separation between private and public areas enhances visitor experience.
05
Ascends to a higher viewpoint, acting as a bridge over the geological crack.

The project explores the connection between geological forces and human experiences within Iceland’s unique landscape. Located near the North American and Eurasian tectonic plates, it introduces the concept of the “PUZZLE.” This concept represents a way to bridge gaps created by geological movements. The building serves as a visitor center, linking the private Kvennagjá cave and the public Karlagjá caves, allowing visitors to engage closely with the natural surroundings.

Modular Path System

A modular path system is central to the design, inspired by the flexibility of the human spine. This design connects different components in a way that promotes movement. As visitors walk along the path, they navigate between different areas of the caves, experiencing the contrasting environments. The system not only guides individuals through the space but also fosters a stronger connection to the surrounding geology. This interactive quality makes the path an essential part of the overall design.

Spatial Organization

Inside the PUZZLE house, spaces are thoughtfully arranged to serve multiple functions while keeping a clear architectural identity. A main distribution point allows easy access to various areas, such as a café, an observation platform, and changing rooms. This layout effectively meets the needs of visitors. Distinct private and public zones enhance user experience, balancing openness with moments of quiet. The design encourages exploration and interaction throughout the building.

Building Form and Materiality

The building has an elongated form that visually connects with the Icelandic landscape. The generous heights provide broad views, linking the structure to its environment. Materials mentioned in the project include reinforced concrete for strength, elastomer bearings for flexibility, and load distribution plates for stability. These materials respond to the geological conditions, ensuring that the structure remains secure and resilient. They contribute to creating a respectful relationship with the surrounding land.

A distinctive staircase ascends to a higher level, designed as a bridge above the geological crack. This feature invites visitors to climb and enjoy unobstructed views of the landscape. Treated as an outdoor space, the staircase emphasizes the connection between people and nature. The integration of form, structure, and context supports a sense of discovery, making it an inviting place for interaction with Iceland’s remarkable geography.

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.
