5 key facts about this project
01
Constructed entirely with local materials to minimize environmental impact.
02
Features photovoltaic panels strategically angled for optimal solar energy capture.
03

05
Designed to enhance visitor reflection on ecological balance and stability.

The project "Tipping Point" is located at the edge of Hverfjall volcano, using the dramatic landscape to engage people with important environmental issues. It acts as an observation platform, inviting visitors to connect with the natural surroundings while considering the effects of climate change and human behavior. The central concept focuses on tipping points, representing moments of critical change in ecological systems and encouraging thoughts about balance and stability in nature.

Geographical Context and Materiality

The platform is made from pre-cast concrete, which provides a sturdy foundation for the stairs and built-in seating. This choice allows for efficient construction and minimizes disruption to the site. Clear balustrade glass, toughened and laminated for safety, enables visitors to enjoy unobstructed views of the surrounding volcano. This arrangement enhances the visual connection between the structure and the landscape, making the experience more immersive.

Sustainability Features

Photovoltaic panels placed strategically on the roof capture solar energy to power decorative LED lighting. This design aspect promotes sustainability, which is increasingly important in modern architecture. The incorporation of renewable energy sources shows a commitment to reducing environmental impact while improving visitors' experiences at the site.

Structural Elements

Galvanised steel gabion cages filled with local basalt stone are a key feature of the design. This material choice not only ensures that the platform remains stable but also builds a connection with the local geology. The use of a powder-coated steel sub-frame and burnt spruce timber cladding balances aesthetics and function, resulting in a welcoming visual effect that invites people to engage with the space.

Accessibility and User Engagement

The observation platform connects smoothly with existing hiking trails, ensuring that it is accessible for visitors. This design consideration encourages exploration of the landscape and promotes responsible tourism in the area. The carefully planned seating arrangements allow for long stays, inviting people to enjoy the surroundings and reflect on the environment.

A noteworthy detail is the design of the seating itself, which is positioned to capture sunlight during the day while providing shelter during bad weather. This allows visitors to remain comfortable and engaged longer, encouraging them to appreciate the beauty of the volcanic landscape.

`
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.
