Crater-Inspired Structure Showcasing Cross-Laminated Timber and Charred Shingles for Celestial Observation

Project in-detail

The design's crater-like form, constructed with cross-laminated timber and charred wooden shingles, creates an optimal environment for celestial observation and enhances community engagement within a naturally integrated landscape.
5 key facts about this project
01
The structure is designed to emulate a natural crater, enhancing the connection between built form and landscape.
02
Cross-laminated timber panels provide both structural strength and thermal efficiency in a harsh climate.
03
Charred wooden shingles offer durability while creating a visually distinctive façade that blends with the environment.
04
The bent A-frame design facilitates optimal sky views for celestial observation while maintaining a compact footprint.
05
Native plant landscaping supports local biodiversity and enhances the building's ecological integration.

Caldera is an architectural project located in Iceland, focusing on an innovative museum design that emphasizes the connection between the built environment and the natural landscape, particularly the aurora borealis. The design integrates a crater-like structure that facilitates an immersive experience while promoting interaction with celestial phenomena. The building's shape and function are intended to draw visitors' attention upwards, showcasing the sky and elevating the overall visitor experience.

Unique Design Approach for Immersive Experience

The architectural design adopts a crater form that transitions from a central apex to gradually lower peripheral edges. This form not only reflects the geological features of the site but also captures and frames views of the sky, creating an inviting space for observers. The primary materials utilized in the construction include locally sourced timber and concrete, which provide structural stability while maintaining aesthetic harmony with the surrounding environment. Large expanses of glass are incorporated throughout the facade, enhancing daylit interiors and allowing natural vistas to flow into the museum.

The design ensures that different interior spaces serve varied functions, including galleries, reception areas, and social spaces. The linear concourse wraps around the primary structure, allowing for smooth circulation while offering vantage points for viewing outdoor features. Strategically placed deep recesses in the walls create interesting lighting conditions that enhance the ambiance of the interior spaces.

Sustainable Material Choices and Landscaping Integration

Caldera prioritizes sustainability through the careful selection of materials and thoughtful integration with the local ecosystem. The use of timber, treated for durability in harsh climates, showcases an ecological approach to architectural construction. The exterior landscape is designed to blend with the existing natural surroundings, featuring native plant species that encourage biodiversity and reinforce local context.

The architectural design is characterized by its consideration of climatic conditions, optimizing both insulation and natural ventilation. The inclusion of shading devices and protective overhangs helps to manage thermal gain while enhancing the external appearance of the building.

For those interested in exploring the architectural aspects of this project further, reviewing the architectural plans, sections, and detailed designs will provide deeper insights into the design strategies and innovative elements employed in the Caldera project. Observing how these ideas translate into practical applications within the museum context will enrich the understanding of its contribution to contemporary architecture in Iceland.

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.
