The twisting form of modular units equipped with green roofs and a grey water recycling system redefines affordable living by enhancing sustainability and community connectivity.
5 key facts about this project
01
Twisting modular units create dynamic interior spaces and enhance visual interest.
02
Each housing unit incorporates a green roof for temperature regulation and biodiversity.
03
A grey water recycling system promotes efficient water use and sustainability.
04
The design utilizes solar panels to generate renewable energy for residents.
05
Community connectivity is prioritized through careful spatial planning and open areas.

The "Twist Out of the Box" project offers a fresh approach to affordable housing by utilizing modular design that emphasizes both practicality and visual interest. Situated in an urban environment characterized by rising housing demands, the design addresses challenges related to space and sustainability. It presents a modern living solution that focuses on adaptability and efficient use of resources, transforming how people interact with their homes.

Modular Construction

The design relies on modular construction methods, allowing for flexibility in the arrangement of spaces. These modules can be customized based on site conditions and residents’ needs. Interconnected units promote community living while optimizing the use of available land. This approach streamlines both the building process and the overall cost, making housing more accessible to a broader audience.

Sustainability Features

Sustainability is a key aspect of this design. Green spaces are incorporated throughout, improving air quality and providing natural insulation. Trees and plants are not mere decorations; they play a significant role in managing indoor temperatures and enhancing residents' well-being. Renewable energy solutions, such as solar panels, support the daily electricity needs of the households, demonstrating a clear commitment to environmentally responsible living.

Innovative Energy Solutions

The project employs innovative systems to further its sustainability goals. A grey water recycling system enables the treatment and reuse of wastewater for gardening and sanitation purposes. This practice reduces waste and supports efficient resource usage. Additionally, the introduction of Plant Microbial Fuel Cell technology harnesses energy from living plants and bacteria, creating a self-sustaining energy source while contributing to the overall eco-friendliness of the design.

Technical Systems

Advanced technical systems are integrated into the design to enhance performance and durability. The mechanical hydraulic automation roof features airtight sealing that improves energy efficiency and protects against harsh weather. These elements reflect a thoughtful understanding of modern urban living needs and ensure a reliable and comfortable home for residents.

Carefully considered design elements encourage natural light to fill the shared spaces. Each aspect is designed not only for function but for creating environments that feel good to live in. The focus on both usability and comfort ensures that residents have a pleasant experience in their homes.

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.
