Basaltic Construction Merging Tectonic Plates with Greenhouse Ecosystem

Project in-detail

Constructed from basaltic rock, the Cave Tower harmonizes with the tectonic landscape of Iceland while integrating greenhouses to promote sustainable agriculture for visitor engagement.
5 key facts about this project
01
Constructed to integrate with the division of tectonic plates in Iceland.
02
Features six greenhouses that support local food production.
03
Pathways connected to cave entrances promote exploration and interaction.
04
Observation platform offers panoramic views of the geological landscape.
05
Utilizes natural geothermal springs for energy and heating.

The Cave Tower is located along the division of the Eurasian and North American tectonic plates in Iceland, an area known for its fascinating geological features and hot springs. The design encourages visitors to connect with the surrounding landscape while highlighting the local geothermal resources found near the Grjótagjá caves. The concept emphasizes the duality of the tectonic plates, creating a space that invites exploration and interaction with nature.

Architectural Form and Spatial Organization

The Cave Tower uses intertwined surfaces to represent the duality of the tectonic plates, serving as both a landmark and a functional space for visitor engagement. The layout promotes vertical movement, guiding visitors through different levels. These levels are designed for interaction with various greenhouse plants and offer open views of the landscape. Starting at the main entrance, which features a narrow opening in the southeastern facade, visitors enter a vertical space that enhances the experience as they ascend to an observation platform.

Pathways and Connectivity

The design features a system of pathways that connect the tower to nearby caves and bathing areas. This careful layout encourages movement and exploration, allowing visitors to appreciate the unique geological context. The pathways guide foot traffic throughout the site, providing opportunities for reflection and interaction with the natural surroundings.

Sustainable Practices and Greenhouses

Six small greenhouses are part of the design, focusing on sustainability and local food production. These greenhouses accommodate plants at different growth stages and promote agricultural education. Visitors can observe plant growth and cultivation, reinforcing the link between architecture and ecology as they walk through these green spaces.

Materiality and Environmental Integration

Basaltic rock and metal wire mesh are the primary materials used in the project. The basaltic rock reflects the local landscape and helps blend the structure into its surroundings. Meanwhile, metal wire mesh supports the architectural form and allows natural light and views to fill the interior spaces. This choice of materials enhances the connection between the Cave Tower and its setting, creating a clear relationship between the built environment and nature.

The observation platform offers wide-ranging views of the tectonic rift, helping visitors understand the scale and beauty of the geological formations in the area. This vantage point illustrates the interaction between human design and the natural characteristics of Iceland’s landscape.

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.
