Cantilevered Observation Platforms Constructed From Local Igneous Rock and Geothermal Energy Integration

Project in-detail

Cantilevered platforms crafted from local igneous rock provide elevated views of Iceland's unique geological landscape while emphasizing sustainability through geothermal energy, serving as an educational hub for visitors.
5 key facts about this project
01
Cantilevered design enhances visitor views of the Northern Lights.
02
Local igneous rock reduces environmental impact and blends with the landscape.
03
Geothermal energy systems are integrated for efficient heating.
04
Visitor pathways connect indoor exhibits with outdoor observation areas.
05
Digital interaction features provide educational insights in real-time.
The Grjótagjá Caves, Earth + Sky Centre is an architectural project located in Iceland that emphasizes the harmonious interaction between natural geologies and human structures. This Centre plays a critical role in facilitating visitor engagement with one of Iceland's significant geological features: the Grjótagjá caves. The design focuses on educational experiences, allowing visitors to appreciate the natural landscape while incorporating elements that enhance interaction with the environment.

The Centre serves multiple functions, acting as both an observation point and an educational facility. The cantilevered design maximizes views of the landscape and provides a vantage point for observing geological phenomena and natural occurrences such as the Northern Lights. Visitor pathways interconnect indoor spaces with outdoor viewing platforms to create a fluid interaction between the building and its surroundings.

Unique Design Approaches

The architectural approach of the Earth + Sky Centre is characterized by the integration of locally sourced materials. The use of coarse-grade igneous rock reflects the surrounding geological context and minimizes the environmental impact associated with material transportation. This choice enhances the building's subsistence within the landscape, showcasing local craftsmanship while emphasizing sustainability.

Innovative technologies such as geothermal energy systems actively contribute to the Centre's sustainability objectives. Geothermal heat pumps provide efficient heating, showcasing a low environmental footprint while maintaining visitor comfort. The incorporation of 5G technology facilitates real-time educational interactions, creating a seamless connection to digital information that relates to the geological features in the vicinity.

Functional Design Details

The cantilevered structure is a pivotal feature of this design, engineered for both stability and visitor engagement. This structural choice fosters an elevated experience, placing visitors among treetops while maintaining safety and comfort. The design includes various viewing platforms, each positioned to provide distinct perspectives of the natural landscape.

The Centre features multiple circulation pathways that guide visitors through diverse environments, facilitating exploration between the indoor exhibition spaces and outdoor observation areas. This spatial organization supports both individual exploration and guided educational tours.

For a comprehensive understanding of the architectural ideas and conceptual frameworks behind the Grjótagjá Caves, Earth + Sky Centre, readers are encouraged to explore further details, including the architectural plans, sections, and design specifics. Understanding these elements will provide deeper insights into the project's architectural significance and its contribution to the broader discourse on environment-focused architectural design.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
