The Ice Cave Tower stands across a chasm that divides two continental shelves. It is designed to fit into a rugged landscape formed by tectonic and volcanic processes. The building is both a unifying element and a marker within this complex environment. With its orientation from east to west, it responds to the prevailing winds and emphasizes a connection to the surrounding land.

Design Concept

The concept behind the Ice Cave Tower revolves around its straightforward and impactful shape. This monolithic structure’s large exoskeletal forms are made from blackened timber, reminiscent of organic structures like a whale’s skeleton. Utilizing timber aligns the building with local construction traditions while providing necessary strength. The design fosters a relationship with the environment rather than overwhelming it.

Geometric Configuration

The architecture features a double square layout, employing regulations derived from the golden section and right angles. This consistent geometric framework creates a sense of balance and proportion in the building. The elevations interact with light and shadow, blending the structure with the natural landscape and enhancing its visual appeal.

Circulation and Experience

Circulation within the Ice Cave Tower is designed for ease of movement. A ramp leads visitors up to a plateau level, allowing access across the chasm. This pathway actively engages people with their surroundings. Large panorama windows are positioned to provide views that encourage contemplation. This connection invites visitors to reflect on both the interior and the natural world outside.

Functional Engagement

Within the design, areas dedicated to education include vitrines that present information about the geological history of the site. This thoughtful inclusion enhances the visitor experience by offering insights into the landscape’s formation and significance. Parking facilities are arranged to support accessibility while maintaining the natural integrity of the location.

The upper level of the Ice Cave Tower contains a mezzanine that looks out over the cave entrance. This vantage point reinforces the connection between the structure and the topography, deepening the visitor's interaction with the land. Every design aspect is intentional, ensuring that each element serves both a practical and a visual purpose.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
