Observation Deck Above Tectonic Fissure Overlooking Natural Landscape

Project in-detail

Perched on a tectonic fissure, the observation deck offers panoramic views of the dramatic landscape while serving as a gateway for visitors to explore the unique geological features of Grjótagjá cave.
5 key facts about this project
01
Observation deck offers unobstructed views of the surrounding landscape.
02
Positioned directly above a tectonic fissure unique to the site.
03
Utilizes existing parking area to minimize environmental impact.
04
Design elements reflect traditional cairn structures found in Iceland.
05
Incorporates semi-open spaces for natural ventilation and light.

The Grjótagjá Cave Tower and Thermal Pool project is located in Iceland, positioned between the Eurasian and North American tectonic plates. It serves as a visitor center and a point of access to the Grjótagjá cave system, encouraging exploration of the area's unique geological features. The design concept focuses on harmonizing with the natural environment while providing essential amenities for visitors.

Design Concept and Structure

The structure consists of two stacked elements, each representing one of the tectonic plates. The first element, aligned with the fissure on the Eurasian plate, establishes a direct connection to the geological landscape. This section functions as the main entrance to the visitor center, containing a semi-open space that includes a café, office, and restroom facilities. These amenities are positioned to cater to visitor needs while enhancing their overall experience.

Tectonic Representation and Observation Deck

The second element of the tower sits on the North American Plate, oriented perpendicularly to the fissure. It rises gradually to create a cantilevered observation deck. This elevated platform gives visitors an opportunity to take in expansive views of the surrounding landscape. The design encourages exploration, allowing individuals to engage directly with the geological features that define the site.

Pathways and Visitor Experience

Carefully designed pathways, including stairs and ramps, enable visitors to access both upper and lower areas. The layout promotes safety while allowing for thorough exploration of the space. Visitors are guided through a series of interconnected areas, enhancing their interaction with the landscape and fostering a deeper appreciation for its unique geological characteristics.

Material Considerations

While specific materials are not detailed, the project suggests a strong relationship with the natural stone and geological elements typical of the Icelandic environment. Existing infrastructure, such as the current parking area, has been reused to minimize environmental disruption and improve accessibility for visitors. This thoughtful approach demonstrates respect for the location while providing a functional space for exploration.

The design culminates in the observation deck, which extends outward and offers panoramic views of the terrain. This design feature effectively connects the structure to the natural contours of the landscape, allowing visitors to engage with the site from a new perspective.

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.
