KUBANTU addresses South Africa's notable housing shortage, focusing on urban settings impacted by economic and social challenges. The aim is to offer more than just shelter; it seeks to create living spaces that help residents become economically active. The design concept emphasizes flexibility, merging living and working spaces within individual units. Each home is tailored to support the varied needs of its residents while encouraging a sense of community.

Materials and Structural Design

The project uses a selection of materials chosen for their function and durability. Aluminium framed windows provide strength and energy efficiency, enhancing the overall comfort of the spaces. The roofs are made from steel IBR sheeting, offering solid protection against weather elements while ensuring stability. Stainless steel burglar bars improve safety without blocking views, allowing for light to fill the interiors.

Functional Spaces

The layout features four key areas: a living space, a kitchen/living room, a private garden, and an office or retail area. This division allows families to blend their professional lives with home life. Residents can engage in activities such as baking, teaching, or trading without leaving their homes. This approach supports local employment and promotes interaction among neighbors.

Environmental Integration

The design emphasizes the connection between indoor and outdoor environments. Each unit includes a private garden, enhancing visual appeal and enabling personal cultivation. These outdoor spaces contribute to the mental well-being of residents, reinforcing the idea of living harmoniously with nature.

Innovative Construction Techniques

KUBANTU employs pre-assembled kitchen blocks to expedite construction and minimize disruption. This method adheres to modern building practices, making the process more efficient. The focus on modular units sets an example for future housing developments in urban areas.

The use of a perforated wall system further enhances the design, allowing airflow and creating visual interest while maintaining security and privacy for residents.

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.
