The E.B.L. microhome is an innovative residential design located in the Mediterranean. It focuses on flexibility and sustainability. Inspired by how bees construct their hives, the microhome offers a unique approach to living, allowing occupants to adapt their spaces based on their needs. The design aims to achieve complete reliance on green energy while maintaining a zero carbon footprint.

Design Concept

The main feature of the E.B.L. is its retractable cork shell. This shell can change shape and configuration, making it an adaptable structure. The ground platform, fixed in place, has low walls that incorporate canvas rolls of different sizes. This design allows for a flexible interaction between the home and its environment. The building's exterior and interior can shift in response to user demands.

Spatial Organization

Inside, the microhome is arranged into three defined zones. The entrance and bathroom form stable modules, while the sleeping and living areas are designed to be flexible. Occupants can move the retractable sections according to their needs, creating spaces that can be used for various activities. This setup encourages personalized living, giving users options to tailor their surroundings.

Materiality

Sustainability drives the choice of materials in the microhome. The cork shell is selected for its insulating properties and durability, enhancing energy efficiency. Canvas rolls serve as adaptable partitions, allowing spaces to change as needed. The use of timber elements adds another layer of natural material to the environment, contributing to a tactile and warm atmosphere.

Technological Integration

A smart application plays a key role in connecting residents with the home’s features. This technology enables users to create furniture, adjust the retractable shell, and monitor weather conditions, all from their devices. The integration of technology signifies an understanding of modern living, supporting functionality in everyday life.

The undulating shape of the retractable shell creates a visual connection between the interior and outdoor environments, reinforcing the project's link to the Mediterranean landscape.

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.
