Cairns of Basalt Rising from the Hverfjall Crater

Project in-detail

Rising from the Hverfjall Crater, basalt cairns create a dialogue between human presence and natural forces, offering a contemplative space for visitors to engage with the landscape.
5 key facts about this project
01
The cairns are constructed from locally sourced basalt fragments.
02
The design reflects the historical geological event that formed Hverfjall Crater.
03
Horizontal planks provide a functional space for visitor engagement.
04
The cairns create a visual contrast with the flat surrounding landscape.
05
The placement invites contemplation of nature's forces and human presence.

The Twin Cairns at Hverfjall Crater reveal a thoughtful response to a landscape shaped by a significant geological event. Located at Hverfjall, a crater formed approximately 2,500 years ago, the project explores the connection between human activities and the environment. The design focuses on assembling local rock fragments into two cairns, reflecting the natural processes that created the area and providing a space for visitors to engage and reflect.

Cairn Design

The two cairns stand more than twice the height of an average person, positioning them prominently against the flat expanse of the crater. This verticality invites attention and interaction, contrasting with the surrounding landscape and prompting visitors to consider their scale. The design enhances awareness of Hverfjall’s vastness, creating a strong visual link between the structures and their natural setting.



Functional Elements

Horizontal planks extend from the base of each cairn, introducing functional spaces for visitors. These planks serve several purposes: they outline the ground area, enhance the visual contrast with the tall cairns, and offer places to sit or stand. The design encourages visitors to pause and engage, framing the relationship between the two cairns and inviting a closer look at the surrounding environment.



Material Context

While specific materials are not detailed in the presentation, using local basalt fragments connects the structures to the geological history of the site. This choice reinforces the idea that the design adds to, rather than disrupts, the natural environment. The integration of these materials enhances the sense of connection between the built forms and the landscape.



The cairns resemble human figures in their upright position, silently observing the passage of time. Their placement at the edge of the crater creates a unique meeting point between nature and human intention. Visitors are encouraged to explore this intersection, fostering an experience enriched by the history of the landscape around them.

`
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.
