### 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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
