Exploring Geological Boundaries Through Columnar Structures

Project in-detail

Set against the dramatic backdrop of Hverfjall Crater, the design utilizes columnar jointing to create a distinctive structure that enhances visitor engagement with its geological surroundings while serving as an observation point for exploration.
5 key facts about this project
01
Designed to integrate with natural geological formations.
02
Incorporates columnar jointing as a key structural element.
03
Provides direct access to the tectonic divide between plates.
04
Optimally positioned for panoramic views of the surrounding landscape.
05
Encourages experiential learning about the local geology.

The Black Rock Balloon project presents a thoughtful blend of architecture and nature in a unique geological landscape near Hverfjall Crater and Lake Mývatn. Its aim is to encourage visitors to connect with the surrounding environment while showcasing the area's geological history. The concept of "Journey to the Boundaries" guides the design, influencing both its form and the experiences it offers.

Geological Influence

Columnar jointing is a key aspect of the design's inspiration. This geological feature is made up of closely spaced fractures that create polygonal columns. It serves as an important visual reference, reflecting the natural processes that have formed the landscape over time. The structure emerges from the earth, creating a connection with the ground and emphasizing the relationship between architecture and nature.

Functional Design

The structure functions as both a landmark and a viewpoint. This dual purpose allows visitors to explore diverse landscapes, including the tectonic divide that separates the North American and Eurasian plates. The design encourages people to engage actively with these geological boundaries. Visitors can walk across lakes and craters, experiencing the land’s features firsthand.

User Experience

The design is crafted to offer various experiences that enhance interaction with the surroundings. It guides visitors to vantage points that reveal different aspects of the natural environment. By inviting exploration, it fosters a greater appreciation for the area's geological characteristics. Spaces within the structure provide opportunities for observation and reflection, creating an enriching experience that connects people to the landscape.

Filtered Light and Views

Natural light is an essential element in the design. The arrangement of openings allows light to pour in, altering the interior atmosphere and enhancing views of the outside landscape. The play of light and shadow invites visitors to engage thoughtfully with the space. This relationship with light not only adds visual interest but also reinforces the connection between the architecture and the environment.

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.
