Curved Pathway and Recycled Steel Watchtower Embracing Natural Caves

Project in-detail

A watchtower constructed from recycled steel rises above a curved pathway that guides visitors through a fissure, enhancing the experience of exploring the unique cave systems in Iceland.
5 key facts about this project
01
A watchtower positioned between Grotagja caves enhances natural landscape observation.
02
Curved pathway connects two continents while allowing exploration of cave systems.
03
Prefabricated CLT panels provide efficient insulation and reduce construction waste.
04
Recycled steel construction minimizes environmental impact and promotes sustainability.
05
Vertical circulation design maximizes views of the surrounding fissure and landscape.

The design embodies a clear vision that connects built form with the natural landscape, situated in a unique geographical setting where two continents are separated by a fissure. The project focuses on enhancing the visitor experience through a winding path that allows exploration and interaction with the surrounding cave systems. A watchtower is positioned strategically between the Grotagja caves, serving an essential role in linking visitors with the natural environment and providing a viewpoint that encourages appreciation for the landscape.

Path Module

The pathway is divided into two distinct types. Type A is constructed using wood and metal and is designed for more challenging terrains and elevated areas. Type B, on the other hand, utilizes local materials such as sand and stone for flat regions. This thoughtful selection of materials not only promotes a connection with the environment but also supports a functional design that enhances the visitor's journey through the landscape.

Spacial Division

Clear divisions of space are established within the design. A dominant pinnacle rises prominently, providing a focal point in the landscape, while a narrow column consolidates secondary functions. Visitors are encouraged to move vertically within the watchtower, and the column guides them horizontally toward the café area. This arrangement maximizes usability and helps create a logical flow throughout the overall project, allowing for a more organized experience.

Visitor Experience

The observation platform includes important functions such as a café, storage, an office, and a waiting area for visitors. These elements are arranged to create connections with nature, promoting an interactive experience. By prioritizing easy access and smooth movement, the design facilitates exploration throughout the site, offering opportunities to engage visually and physically with the geological features.

The structure features prefabricated recycled steel, supporting efficient construction and reducing environmental impact. The exterior is clad in prefabricated CLT panels, which provide insulation and contribute to energy conservation. Additionally, a geothermal heat pump system is integrated to ensure efficient heating, highlighting a focus on sustainability throughout the building’s lifecycle.

A key aspect is the pathway that encourages exploration and discovery. It guides visitors through various perspectives and experiences that shift with movement, fostering a deeper connection to the unique geological and ecological surroundings.

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.
