## Overview

Located in a desert environment, the Heritage Home project embodies a deliberate integration of contemporary architectural methods with traditional design principles. The project emphasizes sustainability, environmental compatibility, and cultural significance, aiming to harmonize with the surrounding landscape while fostering community connections.

### Conceptual Framework

The design conceptualizes the home as an interactive entity, promoting a relationship between habitation and nature through three distinct systems. The **Rigid Mass** forms the foundational structure, utilizing durable materials that accommodate the site's topography while ensuring longevity. A centrally positioned **Prefabricated Volume** functions as a communal hub, facilitating family interactions and enhancing spatial dynamics. The **Natural Mesh** integrates water, light, and vegetation, establishing a dialogue between the interior and exterior and fostering a healthy environment through greenery.

### Materials and Materiality

The selection of materials reflects a commitment to sustainability and craftsmanship. Key components include:

- **Concrete** for structural integrity, ensuring durability.
- **Clay and earth plaster** for walls, contributing to thermal mass and air purification.
- **Mashrabiya wood**, employed in the exterior for creating light patterns while providing privacy and ventilation.
- **Photovoltaic cells** that fulfill energy requirements sustainably.
- Utilization of **recycled materials**, reinforcing environmental responsibility.

### Spatial Organization and Design Outcomes

#### Site Plan and Layout

Designed at a depth of 2 meters below natural ground level, the project enhances thermal stability and energy efficiency. Central to the layout are two courtyards: **The Ghaf Tree Courtyard**, a communal gathering space that features a culturally significant Ghaf tree, and **The Water Courtyard**, providing intimate spaces with a small pool that enhances cooling.

#### Vertical and Horizontal Dynamics

The two-story structure allocates living spaces thoughtfully, incorporating vertical circulation with natural light and airflow strategies. The upper level hosts a **garden roof**, contributing to ecological sustainability while nurturing residents' interaction with nature. Provisions for future expansions ensure adaptability in alignment with the inhabitants' needs.

### Technology Integration

Advanced technologies are employed to enhance energy efficiency and environmental harmony, including:

- **Rainwater harvesting** systems for irrigation purposes.
- **Cross-ventilation systems** that improve air quality while reducing dependence on mechanical cooling.
- **Upcycled carbon floor tiles**, merging aesthetics with sustainability.

### Unique Characteristics

Notable attributes of Heritage Home include its cultural resonance, as the design reflects traditional motifs while prioritizing adaptability for the future. The architecture addresses climatic challenges unique to desert environments and intentionally fosters social interactions, creating a nurturing habitat that goes beyond mere shelter.

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.
