The project addresses the urban challenges faced in Berlin, particularly between Central Berlin, known for its traditional architecture, and Outer East Berlin, characterized by modern developments. It focuses on Plattenbau slab buildings that were originally constructed to alleviate housing shortages after the war. Over time, these monolithic structures have come to represent isolation, as many residents moved to more historic neighborhoods following the fall of the Berlin Wall. The goal is to revitalize these slabs and reconnect them with the community by encouraging interaction and engagement among residents.

Design Concept

The concept revolves around the transformation of Plattenbau slabs into lively community spaces. It emphasizes the interactions between people and their surroundings through the creation of soft, porous spaces that link the buildings. These in-between areas are designed to encourage social connections and can adapt to various urban contexts where similar spaces are currently underused. Each space invites individuals to foster a sense of belonging and participation, reshaping their daily experience.

Spatial Configuration

Using a straightforward slab housing format typical in areas like Lichtenberg and Marzahn, the design aims to maximize space while promoting community activities. Inspiration from the denser districts like Mitte plays a key role in shaping the ground-floor engagement, seeking to create an inviting atmosphere. The integration of concave and convex landforms fosters gathering points. The variety in height and depth expands the interaction between the landscape and users, encouraging exploration and movement.

Circulation and Interaction

Circulation routes in the design are both horizontal and vertical, facilitating easy movement throughout the site. A mesh walkway on the first floor enhances interaction by providing narrow passageways that connect different spaces above and below. This design allows residents to see and experience their environment in new ways. The focus on connectivity between spaces invites engagement, making the community feel more integrated and cohesive.

Roof Structure and Environmental Integration

The roof envelops the in-between spaces and features circular perforations that enhance visual interest. This design not only contributes to the overall appearance of the project but also strengthens the functional relationship with the surrounding environment. The strategically placed openings allow natural light to reach the communal areas below, enriching the spatial experience.

The emphasis on light and openness creates a welcoming atmosphere, highlighting the importance of community interaction and engagement. The roof becomes a defining detail, blending beauty with purpose while encouraging a vibrant social environment.

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.
