## Project Overview

Located in Baja California Sur, Mexico, HOMEBOX represents a progressive approach to sustainable architecture, emphasizing functionality within the context of its natural surroundings. The design prioritizes ecological usability and adaptability, aiming to integrate seamlessly with the local community. Through its thoughtful design, HOMEBOX seeks to foster self-sufficiency and collaborative living practices among its occupants.

## Spatial Strategy

HOMEBOX features a well-defined spatial organization that supports diverse living functions and facilitates social interactions. The two-level structure designates distinct areas for various activities: Level 0 comprises living and dining spaces, a kitchen, and storage, while Level 1 is dedicated to work and living areas, enhanced with an integrated greenhouse for crop cultivation. This open-plan layout minimizes spatial division and encourages versatility, allowing occupants to tailor their environments to their specific needs.

## Material Utilization and Sustainability

The selection of materials for HOMEBOX reflects a commitment to sustainability and environmental harmony. The facade incorporates rammed earth for three walls, providing effective thermal insulation and utilizing locally sourced resources. The frame, constructed from flax fibers and an organic binder, exemplifies innovative material choices that prioritize ecological responsibility. Additionally, windows are crafted from biodegradable glass made from sugar cane, allowing for abundant natural light and maintaining visual connections to the outdoors.

The design features several adaptive elements, including removable wall sections that enable interior customization, as well as multifunctional components that maximize space efficiency. An integrated greenhouse enhances the sustainable ethos by employing natural ventilation and a greywater recycling system for irrigation. Wind turbines support energy generation, reinforcing the project's commitment to environmental stewardship while enhancing the overall living experience.

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.
