Corten Steel Structure Harmonizing with Natural Landscape as a Geothermal Visitor Center

Project in-detail

Constructed from weathering corten steel, the visitor center seamlessly integrates geothermal energy with its modular design, offering visitors a unique vantage point to explore the region's striking geological features.
5 key facts about this project
01
Constructed with corten steel, the structure develops a unique patina that blends with the surrounding landscape over time.
02
The design incorporates geothermal energy systems for heating and cooling, capitalizing on local natural resources.
03
A modular layout allows flexible use of spaces for different visitor activities and events.
04
Expansive glazing provides unobstructed views of nearby geological features, enhancing the visitor experience.
05
The green roof utilizes native plant species, further integrating the structure into its environmental context.

The Tektonisk Tower is an architectural project located in northeastern Iceland, designed to function as a visitor center and observation point. It aims to enhance public access to the stunning geological features of the region, specifically the Grjótagjá caves and nearby Mývatn. This project embodies a synergy between architecture and its natural context, promoting exploration and education about the unique geological landscapes of Iceland.

The design is characterized by modular forms that facilitate interaction with the environment while maintaining a cohesive visual identity. The structure’s massing is carefully composed to respond to the surrounding topography, emphasizing the geological context through its form and materials. The building materials were selected not only for aesthetic appeal but also for their performance under Iceland's variable climate conditions.

Integration of Function and Space

The Tektonisk Tower serves multiple functions, including a café, information center, and observation deck. The layout is organized into distinct zones that guide visitors through the space, encouraging movement and engagement with the natural landscape. The visitor center includes large windows that frame breathtaking views of the geological formations, creating visual connections between the interior spaces and the outdoor environment. This intentional design fosters a sense of place and orientation, enhancing the overall visitor experience.

The observation tower is a key component of the project, elevating its users above the landscape to provide panoramic views of the surrounding area. This design aspect is not only functional but also educational, allowing visitors to appreciate the geological features from an elevated perspective. The incorporation of walking paths around the building enhances accessibility and promotes exploration of the surrounding natural features.

Innovative Material Choices and Sustainable Practices

The Tektonisk Tower utilizes a combination of corten steel, prefabricated aluminum cladding, and local wooden materials to create a durable and visually coherent structure. Corten steel, with its distinctive weathered appearance, integrates well with the rugged Icelandic landscape while ensuring longevity against harsh weather conditions. The aluminum cladding contributes to the building’s lightweight design, minimizing its impact on the site.

Sustainability is a core principle of this architectural project. The building employs geothermal heating and cooling systems, taking advantage of the abundant geothermal energy available in Iceland. Rainwater collection systems further reduce environmental impact and enhance the building’s self-sufficiency. The green roof integrates local vegetation, providing insulation and promoting biodiversity in the area.

The Tektonisk Tower stands out for its integration of architecture and geology, facilitating a deeper understanding of the region's unique landscape. Its thoughtful design and sustainable practices make it an exemplary model for future projects in environmentally sensitive areas.

For a detailed understanding of the architectural decisions and design processes involved in the Tektonisk Tower, readers are encouraged to explore the architectural plans, sections, and designs that provide further insights into this project and its innovative approaches.

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.
