Constructed with recycled OSB and insulated with compacted wheat straw, the modular living system offers customizable housing solutions designed for energy efficiency and functional adaptability.
5 key facts about this project
01
Constructed with recycled pine wood OSB boards for reduced environmental impact.
02
Utilizes compacted wheat straw for superior thermal and acoustic insulation.
03
Modules can be configured independently to adapt to various spatial conditions.
04
Features an innovative interlocking rod system for flexible assembly.
05
Incorporates provisions for photovoltaic solar panels for energy autonomy.

The modular living system has been designed to meet various user needs through a flexible framework. It features five distinct modules, each dedicated to a specific living function. This setup enables individuals and families to customize their spaces according to their preferences and lifestyle. The design not only supports efficient use of space but also emphasizes sustainability within a modern living context.

Modular Configuration

The approach to modularity is practical and innovative, allowing the units to be installed together using interlocking rods or placed separately. This flexibility gives residents the freedom to adapt their homes based on available space or personal choices. It responds well to different environmental conditions, making it suitable for various settings.

Material Composition

Sustainability is a key feature in the construction of the modules. They are built with recycled pine wood OSB boards, which provide strength while minimizing environmental harm. Structural support comes from 3"x3" bars made of eucalyptus wood, secured to the primary wooden framework with iron plates. The walls are insulated with compacted wheat straw sheets, enhancing energy efficiency and providing sound and heat insulation.

Functional Distribution

The layout is designed for everyday living. The living/work/dining room integrates modular sofas and a folding table, allowing for a variety of uses. The kitchen includes large countertops that bring together storage, washing, cooking, and refrigeration into a single area. The bathroom unit features a shower and toilet, enclosed by a white opaque glass screen. In the bedroom, there is efficient use of space with built-in storage, a folding bed, and a desk that can be adapted as needed.

Sustainability Features

Provisions for sustainability enhance the design's practicality. There is potential for adding photovoltaic solar panels to support energy needs. A rainwater collection system is also part of the plan, allowing for the reuse of water in sanitary services and irrigation. These features reflect a commitment to environmental responsibility.

Large glass panels and metal profiles in the enclosure unit create a clear connection with the outside, promoting natural light and views toward the surrounding area. This design choice enriches the living experience by bringing nature into daily life.

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.
