### Project Overview

The Large Void House is situated in a culturally rich region that draws on Arabian design principles. The intent is to create a residence that fosters social interaction and environmental awareness through thoughtful architectural choices. Central to the design is a large void that promotes connectivity among family members while enhancing natural airflow and light penetration throughout the space.

### Spatial Configuration and Flexibility

The residence is organized over two floors with an additional basement. The ground floor is characterized by several key areas designed for communal living, including a majlis for gatherings, a spacious kitchen that opens to living areas, and versatile rooms that can function as offices or guest accommodations. Privacy and accessibility are considered in the arrangement of the bedrooms.

On the first floor, additional bedrooms and a dedicated office space provide options for remote work. Balconies designed for leisure and interaction are incorporated, allowing for adaptability in use as the family's needs evolve. This flexibility is a core feature, reflecting contemporary living requirements and the potential for future reconfiguration.

### Material Selection and Sustainability

Careful attention has been paid to materiality, with reinforced concrete serving as the primary structural element for durability. Perforated grating not only adds a decorative aspect but also facilitates ventilation while offering a cultural aesthetic reminiscent of traditional Arabian designs. Generous glass openings enhance natural daylighting, reducing the need for artificial light.

Sustainability initiatives embedded in the design include cross-ventilation systems that utilize the void for natural cooling, photovoltaic panels that contribute to energy independence, and a green roof that enhances thermal insulation and supports urban gardening. These strategies reflect a commitment to maintaining ecological balance while providing a functional and attractive living space.

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.
