05
Designed to withstand geothermal conditions, ensuring long-term durability.
The Iceland Cave Tower is an architectural project located near Hverfjall volcano in Iceland. This structure serves as an observatory and educational facility, allowing visitors to engage with the unique geological features of the landscape. The design focuses on harmonizing with its natural environment while promoting exploration and appreciation of the surrounding area.

The tower is conceived as an extension of the geological elements it represents, situated at a tectonic boundary where the European and North American plates diverge. This architectural design emphasizes both the connection to nature and the significance of geological movements, positioning the structure as a landmark within its context.

Innovative Design Approaches
The Iceland Cave Tower exhibits unique design characteristics that differentiate it from other observational structures. The orientation of the building is strategically planned to capture panoramic views, utilizing large windows and viewing platforms that bring the landscape into focus for visitors. The vertical form of the tower enables a sense of ascent, making the experience of reaching the top rewarding, as it provides expansive visual access to the surrounding environment.

The division of the tower into two functional halves plays a crucial role in enhancing visitor engagement. Each half serves distinct purposes, integrating observation with educational experiences. This thoughtful approach to spatial organization encourages exploration while drawing visitors to the geological narratives inherent in the site.

Material Selection and Sustainability
The choice of materials is central to the tower's design philosophy. Glulam, or glue-laminated timber, serves as the primary structural element, providing strength while minimizing the environmental impact associated with more conventional materials. The use of cedar wood slats for the exterior enhances the connection to the site through natural textures and tones, allowing the building to blend into its surroundings. Concrete is utilized for foundational stability, particularly important given Iceland's geothermal conditions.

This careful selection of materials demonstrates a commitment to sustainability. By sourcing locally and using materials that resonate with the natural environment, the design reduces its ecological footprint while promoting longevity in the harsh Icelandic climate.

Visitors are encouraged to review the architectural plans, sections, and designs of the Iceland Cave Tower to understand better the innovative elements at play in this project. The architectural ideas represented in this structure highlight the benefits of integrating human experience with the geological features of the landscape.

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.
