## Project Overview
The Kanyi project is located in Chipinge, Zimbabwe, in the rural highlands of the Eastern Highlands. It aims to redefine vernacular housing by integrating traditional design with contemporary architectural approaches. The intent is to create a structure that honors local cultural values while addressing contemporary environmental challenges.

### Design Principles
Rooted in the concept of **kraal**, which signifies the community's connection to the land, the design emphasizes sustainability, resource preservation, and user-focused spaces. The architecture incorporates natural thermal regulation and enhances indoor air quality, aiming to provide an efficient and comfortable living environment. The single unit design features multifunctional spaces, including a granary and kitchen, which facilitate social interactions. The circular layout promotes inclusivity, while the interiors are designed with cost-effectiveness in mind, utilizing local materials and allowing natural light to flow throughout the space.

### Material Selection
Material choices reflect ecological sensitivity and support local craftsmanship. Key materials include:

- **Adobe**: Known for its thermal mass and sustainability, this traditional earth-based material serves as a primary construction element.
- **Timber**: Selected for its local availability and structural qualities, it adds warmth and stability to the design.
- **Mud**: Used in conjunction with other materials, it provides insulation and serves as a bonding agent.

Recycled materials may also be considered during development, illustrating a commitment to adaptability and resource efficiency.

### Community-Centric Design
Phase Q2 focuses on enhancing community engagement through the clustering of multiple units, creating semi-public spaces that encourage communal interaction. Architectural features include rainwater catchment systems, promoting sustainable water usage and integrating ecological considerations into the overall design.

Innovative aspects of the project include the implementation of passive design principles for energy efficiency, an emphasis on cultural resonance through traditional practices, and health features such as smokeless chimneys to mitigate indoor air pollution concerns. These elements collectively foster community ownership and utilize local resources, establishing a foundational model for sustainable rural architecture.

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.
