The Sky and the Earth is located in northeastern Berlin, at the city’s only remaining loam pit. Serving as an observation tower and visitor center, the design aims to highlight the importance of loam pits as historical sources of building materials. The overall concept focuses on creating a strong connection between the structure and the natural environment, inviting visitors to engage with sustainable construction practices.

Rammed Earth Tower

At the core of the design is a rammed earth tower that rises from the landscape. This choice of material supports the project’s sustainable vision, as rammed earth provides natural insulation and promotes a sense of harmony with the surroundings. The thick walls of the tower blend into the greenery, reinforcing the connection between architecture and nature.

Steel Protrusions

Steel protrusions are integrated into the design to enhance structural stability and aesthetics. These elements protect the rammed earth walls from weather conditions while introducing a contrasting material that adds depth to the overall appearance. The combination of earthy and industrial components creates a balanced and thoughtful approach to the architectural form.

Underground Plaza

A significant aspect of the design is the underground plaza, which encourages visitors to explore the layers of soil present below. This space provides educational opportunities, allowing individuals to connect with the geological aspects of the site. By promoting awareness of the local environment and its resources, the plaza supports the project's commitment to sustainability.

Viewing Deck

Visitors can ascend to a raised viewing deck via a winding staircase. This deck is covered by a reflective canopy that mirrors the surrounding landscape. It serves a functional role while also creating a space for reflection and observation. The views from the deck offer a chance to appreciate the broader context of Berlin's topography, emphasizing the relationship between built structures and the natural world.

`
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.
