The Myth of the Monolith is an architectural design situated in Iceland, aimed at guiding visitors toward a series of caves while enhancing their experience of the natural landscape. The project emphasizes a connection between the built environment and the surrounding terrain. Its overall concept revolves around creating a path that prepares visitors for their journey, largely by situating functional spaces underground to shield them from harsh weather conditions.

Design Intent

The project minimizes its visual footprint on the landscape by predominantly housing its facilities beneath the surface. This thoughtful arrangement allows the monolith to rise as a focal point for visitors, providing a clear reference in the otherwise rugged terrain. The journey to the caves begins with an accessible, gently sloped path leading from the parking area, accommodating both pedestrians and those with mobility needs.

Interior Experience

As visitors arrive at the main ramp that leads to the hall, they enter a space filled with natural light. The hall features multiple openings that create an inviting atmosphere for contemplation before exploring the caves. Each area within this space connects to patios that facilitate a smooth transition between indoor and outdoor environments, strengthening the bond with nature.

Central Tower

A central tower, standing 28 meters tall, plays a vital role in the overall composition. Its reflective exterior gives the impression of hovering above the ground, helping it blend into the landscape. The stairways include vertical windows that frame significant views, enriching the experience for visitors as they ascend and take in their surroundings.

Core and Materiality

The design’s core area serves as an atrium and a waiting space, enhancing the overall visitor experience. Natural light enters through various openings, including a central tunnel and skylights, fostering a setting conducive to reflection. Material choices such as exposed concrete, a metal framework with stairs, black steel sheets, clear glass, and a mirror base create an atmosphere focused on durability and practicality while aligning with sustainability goals.

The use of soil and vegetation covers emphasizes environmental integration, providing insulation while harmonizing with the landscape. The reflective nature of the tower encourages visitors to recognize their connection to the surrounding environment, enhancing their overall experience in this unique setting.

`
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.
