## Architectural Analysis Report: Microhome Green Hut

### Overview and Intent
Located in rural settings, the Microhome Green Hut is designed to embody principles of sustainability and adaptability, with a total area of 25 square meters. The project aims to create a harmonious relationship between the living spaces and their natural surroundings, allowing inhabitants to experience a strong connection to the environment while enjoying essential comforts.

### Spatial Strategy and Multi-Functionality
The layout features an open design that accommodates a multifunctional living area, which includes a kitchen, storage, bathroom, and workspace. This flexibility allows the space to adapt to the varying needs of its users. A distinctive open canopy extends the indoor living area, facilitating unobstructed access to the outdoors and offering adaptable shading and shelter.

### Material Selection and Sustainability Features
The hut is constructed primarily using Cross-Laminated Timber (CLT) for robust insulation and a reduced carbon footprint. Prefabricated concrete elements support rainwater management with a built-in capacity of 6.3 cubic meters for water storage. The durability of the metal roof is enhanced by solar panels generating 2400 kW, reinforcing the hut's self-sustainability while maximizing energy efficiency. Additional elements, such as soil pots for sustainable landscaping and steel beams for structural integrity, further contribute to the eco-friendly design.

Interior finishes emphasize natural materials that blend simplicity with functionality, enhanced by large glass panels that maximize natural light exposure and connect occupants visually and emotionally to the landscape. The inclusion of flexible furniture and movable canvas awnings demonstrates a commitment to user adaptability in various conditions, allowing for community engagement through potential interconnection of multiple units.

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.
