### Overview

Bustan is located in Amman, Jordan, addressing significant housing challenges associated with urbanization and increasing population density. The project aims to create sustainable and self-sufficient living environments through the integration of community-oriented design and agricultural spaces, thereby fostering social interaction and environmental responsibility.

### Spatial Strategy and User-Centric Design

The design incorporates residential units alongside community farming areas, reflecting the historical context of orchards in the region. Each dwelling features a rooftop garden, promoting food cultivation and enhancing food security for residents. The layout of the units emphasizes adaptability, accommodating various household sizes and configurations. Multipurpose spaces allow for flexible use, ensuring that the living environment can evolve with the needs of its occupants. Additionally, communal outdoor areas support social interactions, cultivating a cohesive community atmosphere.

### Material and Sustainability Considerations

Bustan employs local precast concrete for its construction, selected for its thermal efficiency, rapid assembly, and reduced transportation impacts. The use of light-colored concrete aids in minimizing heat retention, contributing to indoor comfort in Amman's climate. The integration of solar panels, rainwater collection systems using metal gratings, and strategically placed glass windows enhances energy efficiency and natural ventilation within the units. This approach not only supports sustainability but also emphasizes the project's commitment to utilizing local resources and fostering ecological health within the urban context.

`
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.
