The Microhome 4C-20 is a thoughtful response to the changing needs of modern living. Situated in a context where people often work, learn, and relax at home, this compact structure fulfills multiple functions. The design integrates flexibility and sustainability, making it suitable for a variety of lifestyles. The project focuses on a modular approach that allows for adjustments based on the residents' needs, encapsulating the current trend toward efficient, self-sufficient homes.

Modular Structure

The Microhome is made up of four distinct modules: CORE, COMPANION, COMFORT, and COVER. Each plays a specific role to ensure the overall functionality of the dwelling. The CORE module contains essential mechanical and plumbing systems. Its raised floor not only provides a place for the kitchen but also includes bathroom facilities and storage options. Above this level, there is space for sleeping and a dedicated work nook, accessed by a custom ladder that optimizes vertical space.

Sustainable Living Features

The COMPANION module adds to the home’s self-sufficiency with systems designed to collect rainwater and harness solar energy. This module is critical for managing essential utilities, allowing for a living environment that meets basic needs without relying on outside resources. In combination with the CORE module, it establishes a comfortable and efficient home that emphasizes sustainability.

Adaptability and Outdoor Integration

The COMFORT module expands the overall footprint of the Microhome, offering more areas that can change based on how residents use the space. This adaptability allows for a variety of activities, catering to the dynamic requirements of everyday life. The addition of the COVER module introduces an outdoor terrace and canopy, facilitating a connection to the surrounding environment and providing a pleasant outdoor living area.

Innovative Design Elements

One notable design feature is the greenhouse garden wall. It captures sunlight effectively, promoting indoor plant growth while improving air quality. This wall not only enhances the aesthetic qualities of the home but also serves a practical purpose in food production. Passive heating and cooling strategies are employed, utilizing the greenhouse wall’s ability to store heat during the day and release it at night, maintaining comfort without heavy reliance on mechanical systems. The incorporation of rainwater harvesting and greywater management completes the approach to resource efficiency, making the Microhome 4C-20 a relevant example for future residential design.

`
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.
