3ANGLE is located in Mérida, Mexico, and is designed for a couple. The design prioritizes the relationship between light and shadow, creating a vibrant interior that changes throughout the day. Different forms and angles are utilized in the layout, enhancing the sense of space and encouraging interaction with the surrounding area.

Materiality

Concrete is the primary material used, chosen for its strength and ability to retain heat. This durability is practical for everyday living, while the low maintenance required adds to its appeal. Additionally, the design incorporates recycled and locally sourced materials when possible, supporting the local economy and reducing emissions from transportation.

Natural Light and Spatial Configuration

The design focuses on maximizing natural light and reducing unwanted heat gain. Large windows and skylights are strategically positioned to let in plenty of sunlight. This thoughtful planning improves the comfort inside and creates a strong connection to the outdoor environment.

Integration of Vegetation

Vegetation is an important feature of the design, blending natural elements with the built environment. Plants are included to enhance the appearance of the spaces and promote sustainability. This integration allows for interaction between inside and outside, enriching the living experience and making it more enjoyable.

Spatial Dynamics

The layout reflects a strong interaction between indoor and outdoor areas. The arrangement of spaces encourages movement and engagement, inviting occupants to connect with both the architecture and the landscape. The interplay of light and shadow within the home offers a changing atmosphere, highlighting different aspects of the design and bringing the overall vision to life.

`
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.
