The "House in Voronoi" project presents a thoughtful response to the challenges of urban living, situated by the historic London canals. The aim is to provide modular housing designed for small communities. This approach focuses on sustainable living and encourages social connections among residents. The design is simple yet effective, creating comfortable spaces that nurture a sense of belonging.

Design Concept

The design is informed by the need to address economic, environmental, and social concerns faced by urban residents. By drawing inspiration from the canal system, the layout promotes easy movement and interaction. The housing units are modular, allowing for different family structures and lifestyle needs. This flexibility enhances community engagement and fosters a cooperative living environment.

Spatial Configuration

Three types of housing units make up the layout: family units of 23.38 m², partner units of 14.19 m², and accessible units measuring 21.37 m². This variety provides options for different occupancy needs while ensuring a consistent architectural theme. The arrangement of these homes creates open communal spaces that enhance social interaction and allow for shared experiences among neighbors.

Material Utilization

A sandwich wall system is central to the structure, with a thickness of 15 cm. The outer layers consist of polypropylene panels, noted for their durability and lightness. Between these layers, Thermolon insulation is added to improve energy efficiency and comfort. Sensitive glass is used in the façade, creating air chambers that assist with thermal regulation and help manage energy costs effectively.

Sustainability Initiatives

The project emphasizes self-sufficiency through integrated systems for waste and water management. A system called Kaka captures and purifies water from the environment, providing over 15,000 liters daily. Alongside this, an anaerobic biogas system converts organic waste into usable gas, encouraging residents to adopt eco-friendly practices.

Public spaces are included throughout the design, allowing residents to enjoy natural light and promoting a friendly atmosphere. The arrangement balances private living areas with shared environments, fostering a strong sense of community among those who call this place home.

`
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.
