Basalt-Clad Observatory Featuring Geothermal Heating and Passive Design Strategies

Project in-detail

Constructed with basalt cladding and powered by geothermal heating, the observatory seamlessly integrates passive design strategies to offer a dynamic learning space for visitors to engage with Iceland's unique geological landscape.
5 key facts about this project
01
Basalt cladding mimics local geological formations for enhanced environmental integration.
02
Geothermal heating systems utilize Iceland's natural resources for energy efficiency.
03
Interior fissures guide visitor flow while providing visual connections to the landscape.
04
The structure's passive design optimizes natural light and thermal comfort throughout the year.
05
Segregated zones accommodate both educational programming and casual observation experiences.
The Fissured Stack Observatory is a newly designed architectural project located in Iceland, carefully positioned to provide an unobstructed view of the surrounding geological formations. This observatory aims to enhance visitor interaction with its environment, focusing on education and engagement related to the natural landscape that characterizes the region. The design incorporates elements that reflect the unique geological history of Iceland, creating an immersive experience for its users.

The function of the observatory is dual; it serves not only as a space for public exploration and education but also functions as an observational tower that allows visitors to appreciate the striking geological features of the local area. The building is segmented into various zones that facilitate different activities, ensuring a comprehensive experience for both casual visitors and those seeking to learn more about the geological processes at play.

Unique Aspects of the Design Approach

The Fissured Stack Observatory distinguishes itself through its structural and aesthetic design, drawing direct inspiration from Iceland's volcanic geography. The architecture employs reinforced concrete as its primary building material, which offers durability and embodies the ruggedness of the surrounding landscape. Coupled with basalt cladding, the material palette enhances the relationship between the structure and its site while also providing adequate thermal insulation.

The innovative use of internal fissures shaped into the walls facilitates dynamic circulation flows, encouraging exploration within the space. These fissures, not only sculptural, serve to give visitors an ongoing visual connection with the outside environment, reflecting the cracks and fissures seen in the local geography.

Additionally, the observatory utilizes a passive design strategy that maximizes environmental efficiency. Large openings are strategically placed to optimize natural light, reducing the reliance on artificial lighting and enhancing the overall experience of the space. The observatory also incorporates geothermal heating, aligning with sustainable architectural practices that are increasingly relevant in modern design.

Visitor Experience and Functional Layout

The architectural layout emphasizes clear circulation pathways, providing access to observation lounges and outdoor decks. These spaces are thoughtfully designed to ensure unobstructed views, allowing visitors to engage with the panoramic scenery. The organization of public and educational spaces allows for varying levels of interaction, from informal observation to guided educational sessions.

In summary, the Fissured Stack Observatory is an architectural project that effectively integrates functionality with a deep respect for its natural environment. It serves as a learning hub while offering a unique architectural experience rooted in the geological characteristics of Iceland. For a more in-depth investigation into the architectural plans, architectural sections, and additional architectural ideas that contribute to this project, interested readers are encouraged to explore the full project presentation for further insights.

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.
