### A4 Modular Off-Grid Microhome Overview

Located in the central and northern regions of Slovenia, the A4 Modular Off-Grid Microhome addresses contemporary housing challenges in the context of increasing climate-related disasters. The design merges modern functionality with traditional aesthetics, resulting in a versatile living space that adapts to various environments, from urban areas to rural and mountainous settings. This microhome emphasizes modularity and rapid assembly, directly responding to the urgent housing crisis while minimizing environmental impact.

### Spatial Configuration

Spanning approximately 24.9 square meters, the microhome includes several key modules designed to optimize functionality. The **Large Essential Module (A1)** serves as the primary living area, while the **Small Essential Module (A2)** provides additional living or sleeping space. The **Living Cube (A3)** integrates a closet, bed, and small bathroom, effectively maximizing floor space. A **Module Connector (A4)** enhances the interaction between these modules, ensuring a cohesive flow throughout the living environment. Architectural features such as bay windows enhance natural light and provide scenic views, while multi-functional furniture solutions, including built-in dining benches and storage, maintain a clutter-free environment.

### Sustainable Features

Sustainability is a core aspect of the A4 Microhome, incorporating several eco-friendly technologies. The structure can operate independently, featuring off-grid capabilities through solar panels and wind turbines. A rainwater collection system is included to reduce dependency on conventional water sources, while strategic placement of windows and doors facilitates passive heating and cooling, optimizing energy efficiency. The design also addresses waste management through eco-friendly systems, utilizing incinerating toilets and graywater solutions to minimize environmental impact.

The A4 Microhome exemplifies architectural innovation by offering a flexible living solution that accommodates diverse family sizes and individual preferences, ensuring adaptability as residents' needs evolve.

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.
