**Overview**

The Minimum House is a contemporary architectural prototype designed to optimize spatial efficiency while addressing essential living functions: sleeping, eating, and living. Its layout is organized into three distinct zones—EAT, SLEEP, and LIVE—reflecting a commitment to minimalism and functionality suited for both urban and remote settings. Each area is systematically categorized to ensure the effective utilization of space while maintaining comfort, thereby serving as a practical solution for small households.

**Spatial Strategy**

The arrangement of the Minimum House promotes a cohesive flow among its designated spaces. The EAT zone incorporates necessary dining and cooking facilities, ensuring efficient meal preparation and consumption within a compact footprint. The SLEEP section provides a private retreat outfitted with essential amenities like wardrobes and a bed, enhancing both comfort and accessibility. The LIVE area functions as a multifunctional space for relaxation and social activities, fostering adaptability in the use of interior environments without compromising on spatial integrity.

**Materiality and Sustainability**

This project employs a selection of materials that prioritize sustainability and durability. Charred timber cladding forms a weather-resistant exterior, while the timber structure provides essential support with lightweight characteristics. Ceramic tiles are chosen for their durability and maintenance ease, complemented by double-glazed windows that improve thermal insulation and energy efficiency. Additional features include aluminum window frames for minimal upkeep, vacuum insulation panels for thermal stability, and a quartz countertop in the kitchen designed for durability.

Sustainable systems are integral to the design, with components such as a rainwater collection tank, a water boiler, and a chemical septic tank located in the service area, all reflecting a practical approach to resource management. The incorporation of roller blinds and concealed tracks further enhances light management and privacy, demonstrating a holistic commitment to user experience and environmental responsibility.

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.
