5 key facts about this project
01
Suspended above railway lines to maximize urban space use.
02
Hexagonal modules designed for easy interconnection and customization.
03
Cavities incorporated for efficient service access and water storage.
04

05
Community-focused design enhances social interaction among residents.

The project introduces an innovative modular home concept that offers a new way to think about living in urban environments. Located in areas where space is limited, the design allows for a home that can move with its occupants. It combines the idea of permanence with the possibility of relocation, providing flexibility in an increasingly static world. The overall concept is rooted in the inspiration drawn from natural structures, establishing a deeper connection between people and their habitats.

Design Inspiration

The design takes cues from nature, using forms and patterns found in the environment. It highlights parallels between human-made homes and the shelters created by creatures in the wild. Beehives and nests serve as key references, illustrating the strength and efficiency of hexagonal and multi-level structures. These elements focus on providing not just individual comfort but also fostering a sense of community among residents.

Modular Composition

With a modular layout, the home can easily adapt to different living situations. Individual modules can be used as standalone units or combined to create larger living spaces for families. This adaptability is important for various types of urban dwellers, from singles to larger households. The use of 3D printing technology in construction allows for precision in design and quicker production, enhancing the process of building homes.

Urban Integration

An interesting aspect of the project is its location above railway lines in urban settings, making use of previously underutilized space. This strategic choice increases housing density while preserving valuable ground area for other uses. By transforming abandoned areas into residential spaces, the design contributes to more sustainable planning in cities. Such a focus on repurposing vacant land can lead to more vibrant neighborhoods.

Functional Elements

The design includes practical features such as cavities beneath living spaces for running services and storing water. This thoughtful inclusion showcases a commitment to utilizing space efficiently while addressing real urban living challenges. Each design element serves its purpose, reinforcing the concept of a modular home that balances personal needs with collective living.

The overall vision reflects a commitment to integrating modern needs with ecological awareness, offering a glimpse into future living that supports individuality while enhancing community ties.

`
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.
