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 Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
