Constructed using structural insulated panels, the adaptable terraced houses prioritize accessibility while integrating solar energy solutions, addressing the urgent need for sustainable urban housing.
5 key facts about this project
01
Constructed with structural insulated panels for enhanced energy efficiency.
02
Designed with ground-level access to ensure inclusivity for all residents.
03
Incorporates solar panels to reduce energy dependence on the grid.
04
Features private outdoor patios and terraces to enhance resident livability.
05
Utilizes infill development on brownfield sites to revitalize urban areas.

The design project focuses on adaptable terraced houses located in Melbourne, a city facing a high demand for housing due to its growing population. The approach centers on infill development on brownfield sites. By utilizing these previously used areas, the project aims to revitalize neighborhoods while creating efficient and compact living options for various residents.

Accessibility and Flexibility

The design emphasizes accessibility for all residents, including those with mobility challenges. Each housing unit features a ground-level entrance and adaptable interior spaces that cater to changing needs. Private outdoor areas, such as rear patios and upper-floor terraces, enhance the living experience, offering personal spaces for relaxation and social interaction. These features contribute to a sense of community while providing necessary outdoor access.

Construction Techniques

Structural insulated panels, or SIPs, are the primary material used in construction. These panels consist of two layers of engineered timber enclosing a core of polystyrene foam for insulation. This combination offers excellent thermal performance. Using SIPs allows for a quick construction process, which helps reduce waste and save time. The focus on efficiency in both materials and methods supports sustainable building practices.

Sustainable Features

The design incorporates sustainable elements, such as solar panels that lessen reliance on the power grid and rainwater tanks designed to handle potential water shortages. These features improve the environmental performance of the housing units and show a commitment to responsible urban living. Additionally, mixed-use functions integrated into residential areas further promote local businesses, contributing to a vibrant neighborhood atmosphere.

The layout encourages community interaction by featuring fronts and backs that engage directly with the public spaces around them. This setup fosters a strong identity for the development and invites residents to connect with their surroundings. The thoughtful integration of design elements provides a foundation for a lively community environment that supports various lifestyles.

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.
