## Overview

Located in Dubai, the Kandura Homes project was developed for the Dubai House of the Future International Design Competition 2023. The design integrates traditional Emirati cultural elements with contemporary sustainable practices, aiming to address urban housing demands while preserving cultural identity. Named after the traditional Emirati cloak, the project serves as a response to the evolving architectural landscape in the region.

## Design Philosophy and Spatial Strategy

The Kandura Homes emphasize a balance between heritage and innovation, featuring passive cooling techniques central to the design. A reinterpretation of the *Bajel*, a traditional Persian wind tower, functions as a natural ventilation system, optimizing the homes' thermal mass through strategic shading and outdoor space placement. The layout adopts a sinuous form influenced by traditional Yemeni architecture, promoting both privacy for residents and the fostering of communal living through shared spaces.

Modular design allows for growth and adaptability, facilitating adjustments according to the needs of its inhabitants. The floor plans exhibit distinct zoning for communal, social, private, and intimate areas, with flexible features such as optional privacy screens that accommodate various familial structures and preferences.

## Material Considerations and Sustainability

The selection of materials plays a crucial role in the design's functionality and sustainability. Key materials include **Stax**, composite building blocks utilizing desert sand for enhanced thermal performance; steel and membrane components for adaptable interior spaces; and traditional mud and natural fibers that enhance cooling while maintaining cultural connections. These materials support structural integrity and energy efficiency, reflecting a comprehensive approach to sustainable architecture.

The project also features advanced passive cooling strategies, such as wind towers and shaded walkways, significantly reducing reliance on mechanical cooling systems. Additionally, the incorporation of photovoltaic cells into the rooftops emphasizes a commitment to renewable energy, aligning with the overarching sustainability goals of the design.

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.
