The Creek House project is located along the Moonee Ponds Creek in Melbourne, Australia, focusing on affordable housing with a strong emphasis on environmental care. It aims to provide a solution for those seeking accessible living spaces while also revitalizing the local ecology. The design incorporates modular units raised on stilts, which allows for better integration with the natural surroundings. This approach not only makes the most of the landscape but also encourages community interaction among the residents.

Modular Design

The layout comprises three prefabricated units that sit on a raised platform. Two of these units serve as living spaces with areas for sleeping and working. The central kitchen unit connects the other units and features a courtyard designed to collect rainwater. This arrangement helps use the available space efficiently while addressing the diverse requirements of residents. The inclusion of sliding folding shutters adds flexibility, allowing the units to adapt to different weather conditions.

Sustainability Features

A major aspect of the design is its focus on sustainable practices. The rainwater harvesting system enables the houses to operate off-grid, reducing reliance on local water supplies. A biogas system is linked to both the kitchen and a bio-toilet, which allows for effective waste management and resource recovery. Green roofs on the units provide insulation and support local wildlife, aligning with the project's goal of promoting environmental responsibility.

Community Integration

The Creek Houses are connected by shared spaces that encourage social interaction. These communal areas serve as venues for gatherings, helping to strengthen relationships among residents. By fostering social ties, the design not only meets housing needs but also creates a welcoming community environment.

Materials play an important role in the overall design. Corrugated sheets made from recycled Tetra Pak beverage cartons are used for the external walls. This choice ensures durability, resistance to various weather conditions, and safety from fire. By using recycled materials, the project emphasizes sustainability and shows how modern living can be both functional and environmentally aware.

`
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.
