Basalt Façade and Geothermal Design in Harmony with Volcanic Terrain

Project in-detail

With a basalt façade that integrates seamlessly into the volcanic landscape and a design that harnesses geothermal energy, the facility serves as a sustainable visitor hub that enhances the natural experience of Iceland's unique environment.
5 key facts about this project
01
Basalt is the primary material, reflecting the local geological landscape.
02
The design incorporates geothermal heating systems for energy efficiency.
03
Reflective surfaces are used to mirror the surrounding environment.
04
The bent A-frame design optimizes structural stability and aesthetic integration.
05
Multi-functional spaces promote community interaction and environmental engagement.

The architectural design project "The Magma Tect" is a contemporary exploration of integrating built environments with the unique geological characteristics of Iceland's volcanic landscape. This project harmonizes architecture with natural processes, utilizing local materials while promoting sustainability. The design is influenced by the concepts of lava tubes and natural formations, resulting in a structure that complements the surrounding terrain.

The primary function of "The Magma Tect" is to serve as a multi-purpose facility that includes a visitor center, communal spaces, utility areas, and amenities such as changing rooms and a café. These components facilitate interaction with the natural landscape, embodying a seamless connection between indoor and outdoor environments.

The project showcases a variety of key architectural elements. It features an Aerial Hall as the central gathering area, where users can engage in social and recreational activities. Utility areas for resource management are strategically placed and designed for efficiency. The use of geothermal heating systems exemplifies a commitment to sustainability, leveraging Iceland's natural geothermal energy resources.

Unique aspects of the design include the extensive use of basalt, a volcanic rock abundant in the region, which gives the building its contextual integrity. The arrangement of spaces takes advantage of natural light, while mirror surfaces are employed to reflect the landscape, further integrating the structure into its environment. This strategic use of high-quality materials aids in energy efficiency and enhances the overall aesthetic.

The design approach prioritizes a deep understanding of the site’s ecological conditions, resulting in a project that not only accommodates human activities but also respects and reflects its natural setting. By addressing both functional and sustainable design aspects, "The Magma Tect" stands out among architectural examples in similar contexts.

For those interested in a deeper understanding of the architectural ideas behind "The Magma Tect," exploration of the architectural plans, architectural sections, and architectural designs presented in the project documentation is encouraged. These elements provide further insights into how the design effectively integrates with its environment while meeting user needs.

`
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.
