### Project Overview

Located in a culturally rich region, El Dorado represents an exploration of a harmonious living environment that emphasizes a connection to nature and the well-being of its occupants. The design integrates contemporary architectural practices with elements that reflect local culture, resulting in a dwelling that balances modernity with tradition. Thoughtful consideration of layout, material selection, and environmental factors contributes to a holistic approach to contemporary living.

### Material Selection and Sustainability

The project utilizes a diverse range of sustainable materials sourced locally to minimize environmental impact. **Compressed Earth Blocks (CEB)** serve as the primary construction material, enhancing energy efficiency and reducing carbon footprints. **Clay Breezeblocks** facilitate natural ventilation and daylight while reflecting local architectural styles. Interior finishes predominantly feature warm wood elements, creating a tactile link to the surrounding environment. Concrete and cement provide structural integrity, while the integration of vegetation throughout the design contributes to improved air quality and overall aesthetics. These materials not only fulfill functional requirements but also resonate with the intent of establishing a deep connection to the locality.

### Spatial Configuration

El Dorado's spatial arrangement centers around a **courtyard**, which acts as a vital communal space, promoting interaction and enhancing the flow between different zones of the house. The **ground floor** comprises an adaptable entryway that serves dual functions as a kitchen and dining area, encouraging a welcoming atmosphere. Surrounding this central space are family living areas, workspaces, and utility zones, all strategically oriented toward the courtyard. The **first floor** features four bedrooms designed for privacy, each offering views of the surrounding green spaces, thereby enriching the experience of natural light and connection to outdoor environments.

The design incorporates traditional elements such as the **Mashrabiyya** system to aid in ventilation while maintaining privacy through intricately crafted wooden latticework, demonstrating a commitment to cultural integration and community-centric planning. Additionally, green roofs and water-efficient systems enhance biodiversity and sustainability, further reinforcing the commitment to ecological responsibility within 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.
