The space invites personal reflection on themes of separation and reunion.

The Hour of Pearl is a memorial located in Berlin, designed to express the deep connections that form amidst the challenges of love and conflict during the Cold War. The design features two reinforced concrete walls that curl toward each other, symbolizing the merging of divided lives. This thoughtful approach invites visitors to experience a journey through separation and reunion, grounded in the cultural significance of Berlin.

Design Concept

At the heart of the memorial are the two intertwining walls. Their gentle curves create a space that represents both unity and the longing for connection. This form honors individuals who wished to reunite with loved ones during a time of great division. Visitors are welcomed to reflect and find meaning in the space, experiencing the nuances of personal and shared histories.

Materiality

The structure integrates a Litracon concrete aperture, allowing light to filter through and cast a warm glow. This feature enhances the memorial's ambiance and conveys themes of hope and enlightenment. The presence of a laminated wood door adds a tactile contrast to the concrete, introducing warmth and approachability to the overall design.

Environmental Engagement

An LED light panel contributes to the atmosphere within the memorial by creating dynamic lighting effects. This technology not only highlights the architectural features but also connects the memorial to Berlin's artistic culture. The sounds of techno music echo in the background, enriching the visitor experience and linking the memorial to contemporary expressions of creativity.

Narrative Depth

The Hour of Pearl addresses important themes of division, resistance, and reunion, creating a space that reflects complex historical narratives. Each design element works in harmony to foster personal reflection while honoring collective memories. It engages visitors in a dialogue about the legacies of separation and the enduring power of human connection.

As light dances across the interior surfaces, shadows shift and change, drawing attention to the way illumination transforms the space. Moments of contemplation arise as visitors engage with this interplay, enriching their experience within the memorial.

`
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.
