5 key facts about this project
01
Utilizes a 4 ft x 4 ft structural "C" module for flexible configurations.
02
Incorporates a charred cedar exterior for enhanced durability and low maintenance.

The 4Block Home is a modular dwelling that aims to provide affordable and adaptable housing solutions. Located in an urban setting, it fulfills the need for a functional living space that is both efficient and sustainable. The design concept focuses on pre-fabricated modules that can be locally produced using renewable materials, making it easier for individuals and families to achieve home ownership.

Modular Design

The structure uses a unique “C” module format, based on a standard 4 ft x 8 ft plywood board. This design allows for various configurations, creating rooms that are intimate yet practical. Every space is deliberately arranged to serve essential functions, ensuring that living areas, kitchens, and entryways work well together. This careful layout enhances comfort while making the best use of limited space.

Indoor-Outdoor Connection

A strong connection between inside and outside is a key feature of the design. The inclusion of outdoor patios and folding glass doors invites natural light and encourages interaction with the outdoor environment. This feature allows residents to easily transition from the interior to the exterior, creating opportunities for social interaction and enjoyment of the landscape.

Material Composition

Materials are chosen for both their performance and sustainability. Plywood forms the backbone of the structure due to its flexibility and affordability. The roof consists of corrugated metal panels, known for being lightweight and durable. Insulation made from wood fiber improves sound absorption and is an environmentally friendly option, as it utilizes waste products. Mineral wool insulation is incorporated into the flooring to enhance energy efficiency.

Structural Integrity

The building's framework relies on 2x wood framing for rafters, walls, and floors. This choice ensures strength and stability while meeting building standards. The exterior is finished with charred cedar, which offers protection against moisture and pests, requiring low maintenance. This thoughtful material selection underscores a commitment to creating durable and lasting homes.

The thoughtful integration of functional spaces, materials, and design elements results in a dwelling that supports its residents while being considerate of the environment. Each choice reinforces a practical approach to modern living, aiming to meet the diverse needs of today’s households.

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.
