Utilizing a dynamic roof system and a hydrogen energy generator within a modular earth structure, the design enhances efficiency and sustainability while providing adaptable living spaces for families.
5 key facts about this project
01
Hydrogen energy generator integrated into the structure for self-sufficiency.
02
Dynamic roof system allows for climate-responsive shading and ventilation.
03
Modular grid layout enhances space adaptability for future modifications.
04
Rammed earth construction provides thermal mass and eco-friendly benefits.
05
Vertical gardens incorporated throughout the design promote biodiversity and air quality.

**Overview**
The Wall House is designed as a contemporary residential prototype that emphasizes sustainability and technological integration within a defined urban context. Occupying a 30m by 15m plot, the architectural approach balances living spaces with garden amenities by utilizing innovative building techniques that prioritize efficiency and environmental consciousness.

**Spatial Strategy and Organization**
The layout is systematically divided into two functional areas: the building and a garden. A modular 3.65m grid underpins the spatial organization, contributing to the functionality of the overall design. The ground floor accommodates parking for two vehicles, an entrance leading to the basement, and a Majlis, fostering social interaction. An open floor plan connects the family room, kitchen, and utility spaces, promoting multifunctionality. The first floor comprises four bedrooms, with options for future expansions ensuring adaptability for family needs, while the basement supports both communal and service functions, establishing a clear separation between public and private domains.

**Material Palette and Technological Integration**
The selected materials reflect both aesthetic appeal and ecological responsibility. Prefabricated clay plaster walls and rammed earth elements provide thermal mass and structural integrity, while transparent solar PV panels enhance energy efficiency without compromising natural light. Features such as motorized sliding musharabiah facilitate climate control and visual connectivity, complemented by hydroponic vertical gardens that optimize space and improve air quality. Key technological integrations include a hydrogen generator that operates with solar power, enabling off-grid functionality, and a wall that incorporates MEP systems for maintenance ease and automation control. Furthermore, the design thoughtfully addresses the microclimate through strategic orientation and window placement, enhancing natural ventilation and minimizing mechanical cooling needs.

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.
