### Project Overview

Ilé Kékéré, which translates to "small house" in Yoruba, is an architectural intervention located in Nigeria, aimed at alleviating the ongoing housing deficit in the country. Designed specifically for a young professional couple, the project occupies a compact 25-square-meter footprint and emphasizes modularity, sustainability, and self-sufficiency. It addresses the challenges of urban living in Nigeria and promotes accessible housing solutions within a metropolitan context.

### User-Centric Spatial Strategy

The design employs an open-plan layout, fostering flexibility to adapt to the inhabitants’ diverse needs. Essential functional areas—including a living space, kitchen, bath, and bedroom—are strategically arranged to optimize space utilization and maintain comfort. This approach emphasizes human-centered design, ensuring that every element contributes to an inviting and practical living environment.

### Climate Responsive Materiality and Construction

The project responds to Nigeria's tropical climate by implementing specific strategies for ventilation, insulation, and solar orientation to enhance thermal comfort and energy efficiency. The use of locally-sourced materials, such as Kingspan insulated roof and wall panels, gypsum ceiling board, and timber flooring, supports sustainability goals while minimizing environmental impact. Additionally, the incorporation of features like panoramic windows enhances natural light and integrates the indoor space with the external environment. Noteworthy elements include a hydroponic tower for food production, underscoring a commitment to self-sufficiency and innovative urban living.

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.
