"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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
