"ABSIDIS CIVITATEM" is an architectural design that addresses modern housing challenges through the concept of a floating unit. Located by the coastal lake Jamno, the design connects with the history of the nearby village, known for its roots in the Middle Ages. The overall concept balances contemporary living needs while respecting the historical context of the region.

Design Concept

The project brings together elements of sacred and everyday life, using the simple shape of a traditional church as a central idea. This choice honors the cultural significance of the church while also adding depth to the design. The form of the building encourages a sense of community, reflecting the social role that churches have historically played.

Functionality and Adaptability

A key aspect is the ability to adapt to the users' needs. The design features a flexible workspace that combines a desk and armchairs with a casual area that includes a sofa made from mattresses. This practical setup allows for easy shifts between working and living environments. The desk and chairs slide into the wall, making the best use of available space. The sofa can also be converted into a bed, offering more versatility for residents.

Sustainability and Utility

The building rests on a concrete float that includes a tank for water and waste management, promoting independence and environmental responsibility. Movable blinds with solar panels contribute to energy efficiency, ensuring the unit is less reliant on outside energy sources. Together, these features provide a comfortable living experience while addressing sustainability concerns.

Community Connection

The design emphasizes orientation, with glass walls facing the lake to enhance the scenic views. This layout creates a direct link between indoor and outdoor spaces. Concrete floats serve as pathways that connect the units, supporting interactions among residents. This community-focused feature echoes the historical function of churches, enhancing social ties in the living environment.

Sliding ladders offer access to mezzanine areas and add another layer of functionality to the interior. This design detail optimizes vertical space and reflects a thoughtful approach to residential living.

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.
