Floating Volumes with Soil Cement Structure Emphasizing Inverted Views of the Icelandic Landscape

Project in-detail

Comprising floating volumes and utilizing soil cement, the design captures inverted projections of the Icelandic landscape to create an immersive observation experience.
5 key facts about this project
01
Utilizes soil cement for structural stability and environmental integration.
02
Features four floating volumes designed for optimal light exposure.
03
Incorporates a camera obscura technique for dynamic image projection.
04
Provides a progression from dark to light chambers during ascent.
05
Emphasizes geothermal heating and rainwater collection for sustainability.

CAMERA ALTERNA is located in the striking basalt landscapes of Iceland, near Myvatn's lake. Serving as an observation tower, it invites visitors to re-experience the natural surroundings while exploring themes of perception and reality. The design integrates light and shadow to foster a deeper connection to the environment, transforming standard viewpoints into engaging experiences.

Architectural Concept
The main idea of CAMERA ALTERNA is centered around experiential exploration, where the structure acts as both an observation point and a sensory interface with nature. A key element of the design is the "camera obscura," which uses a dark chamber to project an inverted image of the landscape outside. This setup highlights the unique features of the surroundings, creating an atmosphere that shifts with the light throughout the day. The design follows the accordion shape of traditional view cameras, which helps achieve a precise focus for visual projection.

Structural Organization
Within the design, four floating volumes interact thoughtfully with the landscape. These volumes are positioned to capture light during the day and transform into glowing elements at night. This relationship between light and structure encourages exploration and enhances the experience of the environment. As visitors ascend through a series of interconnected dark chambers, they move from shadow to light, creating a dynamic journey and reshaping their view of the landscape.

Materials and Sustainability
Materials mentioned in the construction include soil cement, which provides support for the entrance, reception area, and cafeteria. This choice links the structure to the ground. The main framework employs a steel system that gives the appearance of floating volumes above the landscape. Additional elements enhance sustainability, such as solar panels, geothermal heating, and rainwater collection. These features reduce the environmental impact while ensuring the structure functions responsibly within its natural context.

Illuminated chambers at night serve as beacons, guiding visitors while framing shifting views of the Icelandic terrain. The interplay of light and shadow enriches the overall experience, allowing moments of reflection and connection between people and the landscape.

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.
