## Overview

The Micro Hope Ensemble is situated in Gaza City, addressing the critical demand for affordable and sustainable housing in a context marked by significant humanitarian challenges. The design seeks to foster community resilience while incorporating environmental sustainability through innovative architectural solutions. This initiative emphasizes modular growth, the utilization of local materials, and sustainable building practices tailored to meet the specific needs of the Gaza community.

## Spatial Strategy

The ensemble's design features modular housing units that offer flexibility in layout and adaptability to various family structures. Each unit is carefully organized to optimize space utilization while ensuring privacy, a key consideration in Arab family life. Public, semi-private, and private areas are distinctly defined to enhance livability in accordance with cultural norms. Additionally, the internal configuration promotes functionality, allowing residents to customize their environments as family dynamics evolve.

## Materiality and Sustainability

The project employs locally sourced materials that reflect both resourcefulness and a commitment to sustainability. Cob bricks and mud bricks are selected for their thermal efficiency, while recycled concrete aggregates sourced from conflict-related debris contribute to waste reduction. Recycled wood panels reinforce structural integrity, and natural shading solutions using jute and straw enhance indoor comfort. To further support sustainable living, photovoltaic panels provide off-grid energy generation, and hydroponic systems facilitate water recycling for household use. The design also incorporates rainwater harvesting systems, addressing local water scarcity effectively.

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.
