Lava Rock Cladding and Wood Lattice Structure in a Geothermal Visitor Center

Project in-detail

Incorporating lava rock cladding and a wood lattice structure, the center leverages geothermal energy to blend seamlessly with the volcanic landscape while providing educational resources for visitors.
5 key facts about this project
01
Lava rock cladding integrates the structure with its volcanic surroundings.
02
The wood lattice roof enhances natural light while providing ventilation.
03
Icelandic wool insulation contributes to energy efficiency and local material use.
04
Geothermal systems ensure sustainable energy management throughout the year.
05
The tiered layout maximizes views and visitor engagement with the landscape.

The architectural project is a contemporary visitor center designed to engage guests with the surrounding volcanic landscape. This facility not only serves as an operational hub for tourism but also offers educational resources about the geological features inherent to the area. Blending functional requirements with environmental considerations, the project employs a thoughtful design approach that emphasizes local materials and sustainable practices.

Connection to the Landscape

The visitor center's architecture is closely aligned with its geographical context, characterized by a cascading structure that follows the natural contours of the site. This approach helps to minimize disruption to the landscape while creating diverse spatial experiences across multiple levels. The building's form is accentuated by large openings that frame scenic views, allowing visitors to feel immersed in the surrounding environment.

Sustainability is a core component of the design philosophy. The use of locally sourced materials, such as lava rock for cladding and Icelandic wool for insulation, reinforces ecological responsibility and enhances the building's thermal performance. Additionally, the incorporation of geothermal energy systems reflects a commitment to reducing the overall energy footprint, aligning with modern sustainable architectural practices.

Unique Structural Elements

The architecture features a distinctive roof design characterized by a flowing wood lattice structure. This element not only provides shade and visual interest but also serves as a critical component in managing ventilation and light within the building. By allowing light to filter through the lattice, the design creates a dynamic interior atmosphere that changes throughout the day, enhancing the visitor experience.

Spatially, the layout is divided into three key levels that serve various functions. The ground level accommodates essential facilities such as a café and restrooms, focusing on accessibility and visitor services. The intermediate level hosts educational displays and viewing areas, promoting engagement with the geological context. Finally, the upper level offers observation points that provide expansive views, encouraging visitors to appreciate the striking landscape from unique vantage points.

Material Composition and Aesthetic Integration

The selection of materials plays a crucial role in the overall aesthetic and functionality of the building. The exterior cladding features traditional lava rock, which ties the structure to its geological environment, while the wood elements introduce warmth and comfort. The use of tempered glass enhances views and natural lighting, reinforcing the connection between the interior and exterior spaces.

Additionally, the design's careful planning reflects an understanding of visitor flow and experiences. Key transitions and circulation paths are positioned to facilitate movement while ensuring that points of interest are easily accessible. This structured approach improves the operational efficiency of the visitor center while maintaining a welcoming atmosphere.

In summary, this architectural project stands out due to its integration of local materials, sustainable energy practices, and a strong connection to the surrounding landscape. The thoughtful layout and distinctive structural elements work together to create an engaging visitor experience. For those interested in gaining a deeper understanding of the architectural ideas and design elements, reviewing the architectural plans, sections, and designs will provide further insight into this compelling project.

`
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.
