Basalt-Clad Viewing Tower Embracing Iceland's Tectonic Landscape

Project in-detail

Clad in local basalt and oriented along cardinal directions, the viewing tower offers visitors expansive views of Iceland's tectonic divide while promoting an immersive connection with the surrounding geothermal landscape.
5 key facts about this project
01
Clad in basalt, the structure harmonizes with the surrounding geology.
02
The tower is oriented along cardinal directions to enhance viewing experiences.
03
Access points are designed to flow seamlessly between built and natural environments.
04
Vertical design encourages elevation and exploration of the landscape.
05
Openings in the upper level frame significant views of the tectonic divide.

Grjótagjá: Reconfiguring a Geometry is located in the geothermal landscape of Grjótagjá, Iceland. The design aims to create a landmark that interacts with its natural surroundings while serving a functional purpose. Through a clear geometric concept, characterized by simple forms and noticeable height, the architecture stands out against the rolling terrain of the area.

Geometric Arrangement

The building is organized along the four cardinal directions—North, South, East, and West. This specific layout enhances the connection between the structure and the landscape. Openings in the tower allow visitors to take in views of important natural features, especially the tectonic divide. The organization results in a visual conversation between the constructed spaces and the surrounding geological context.

Vertical Experience

The design emphasizes verticality, creating a viewing tower that rises above its surroundings. This height encourages exploration and offers various perspectives for those who visit. As individuals ascend through the different levels, they gain access to the raised walkway at level one, promoting an easy flow through the building.

Material Contextuality

The materials used in the project are key in reinforcing ties to the site. The viewing tower and its accompanying buildings are clad in basalt, aligning them with the geological characteristics of Grjótagjá. This use of local stone helps to blend the structures into the natural environment, providing a strong sense of place.

Visitor Engagement

The design considers how visitors will interact with both the building and the landscape. At the café and information center, people can gather details and plan their visits. A clear path from the structured areas to the natural caves supports a natural transition between built and unbuilt spaces. A linear layout draws attention to the surrounding views and emphasizes the relationship between movement and observation within the landscape.

From the uppermost level, large openings in the tower allow light to enter and provide wide views of the area below. This interplay of light and structure enhances the experience for visitors, encouraging them to reflect on the natural beauty surrounding Grjótagjá.

`
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.
