Dark Tuff Roof Reflecting Tectonic Movement in a Community Café

Project in-detail

Constructed with a dark tuff roof that echoes the tectonic movements of the Hverfjall volcano, the café integrates seamlessly into its dramatic landscape while providing a communal space for visitors and locals alike.
5 key facts about this project
01
Dark tuff roof mimics the surrounding volcanic landscape.
02
The building mass appears to be separated along a tectonic axis.
03
Vertical shifting of roof plates enhances spatial dynamics.
04
Glass blocks optimize natural light throughout the interior.
05
An overhanging slab connects indoor and outdoor spaces seamlessly.

The coffee shop at the Hverfjall volcano is designed to fit into the unique geological landscape defined by its dark tuff surface. It serves as both a gathering space for the community and a destination for visitors interested in the natural environment. The design aims to highlight the relationship between the building and its surroundings, using the concepts of geological movement to create an engaging and visually interesting structure.

Concept and Massing

The design illustrates a sense of movement, as if the building’s mass is being “ripped apart” along a north-south axis. This visual interpretation reflects the tectonic processes of the area, connecting the architecture to the natural forces that shaped the landscape. By creating variations in mass, the building evokes a narrative of displacement and geological activity, inviting curiosity from those who approach it.

Spatial Organization

Inside, the layout begins with a welcoming lobby that leads into an exhibition hall. This gradual opening of space allows visitors to experience a sense of flow as they navigate through the building. The design culminates in a café that is meant for socializing, encouraging visitors to gather and interact. The clear arrangement of spaces makes it easy to move around while keeping a strong link to the outside environment.

Material Integration

The roof of the coffee shop is constructed from dark tuff, which helps it blend into the surrounding volcanic terrain. This material choice strengthens the connection between the built environment and the natural landscape, as the roof’s contours are aligned with the site’s topography. The integration of this material enhances the visual and physical presence of the building within its setting.

Natural Light and Atmosphere

The design features vertical shifts in the roof plates, introducing dynamic spatial qualities. Glass blocks are strategically located to allow natural light to filter into the interior. This light adds a warm and inviting feel to the space, creating an atmosphere that connects visitors with the changing outdoor environment. The careful placement of these elements enriches the sensory experience as one moves through the building.

The design is completed with an overhanging slab that connects the interior to an outdoor terrace. This space invites visitors to step outside, reinforcing the establishment’s ties to its dramatic volcanic surroundings. The overall form and function reflect a thoughtful approach to architecture in harmony with nature.

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.
