Fractured Forms with Birch Wood and Natural Bedrock Overlooking Tectonic Landscapes

Project in-detail

A fractured cubic form integrates birch wood cladding and natural bedrock, responding to the geological landscape of Iceland's Mid-Atlantic Ridge while serving as a visitor center and exhibition space.
5 key facts about this project
01
Fractured design reflects tectonic shifts in the Mid-Atlantic Ridge.
02
Integration of natural bedrock enhances visitor engagement.
03
Two distinct volumes create varied spatial experiences.
04
Locally sourced birch wood cladding fosters regional connection.
05
Darkened ascent culminates in expansive landscape views.

The Cracked Cave Tower is located overlooking Iceland's Mid-Atlantic Ridge, a place known for its active geology and shifting landforms. Serving as a visitor center and exhibition space, it emphasizes the connection between the building and the landscape. The design is rooted in the idea of fragmentation, featuring a cubic form that has been intentionally broken and rearranged, reflecting the natural forces that shape the area.

Design Concept

The concept centers around fracturing a simple cube into two interlocking volumes. This split not only mirrors geological movement but also creates a responsive relationship between the two segments. By slicing through the cube diagonally, the design embodies the earth's shifts and brings a dynamic quality to the structure, resulting in a coherent yet engaging form.

The White Cave and The Black Tower

At the heart of the design are two key spaces: The White Cave and The Black Tower. The White Cave serves as a visitor center and incorporates the natural bedrock into its floor design. This approach enhances the connection to the site and invites visitors to engage with the earth beneath them. The space encourages both reflection and interaction, creating a calm environment that aligns with the surrounding landscape.

On the other hand, The Black Tower provides a different experience. Visitors ascend through a darkened staircase, leading to a platform that reveals expansive views of the Mid-Atlantic Ridge. This vertical movement facilitates engagement with the landscape, allowing people to appreciate the dramatic features of the terrain while reinforcing the relationship between nature and architecture.

Sustainability and Materiality

Sustainability plays a crucial role in the design of the Cracked Cave Tower. Strategies for environmental responsibility include careful positioning to maximize sunlight and a walking path designed to minimize ecological impact as it connects the parking area to the entrance. Materials used in the construction feature locally sourced birch wood planks for cladding, finished with a tarred surface. This selection supports local resources while maintaining a consistent visual appearance throughout the project.

The integration of the Cracked Cave Tower with its surroundings culminates in thoughtful design details. Each element interacts meaningfully with the rugged Icelandic landscape, creating a space that exists in harmony with its environment.

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.
