### Overview

Casa Macondo is situated in the Chichamocha canyon region of Colombia, designed to align with both sustainability principles and local cultural identity. Commissioned by Chimila and Guanneta, the intent was to create a residence that serves not only as a home but also as a sanctuary fostering creativity and a sustainable lifestyle, reflecting a harmonious relationship with the surrounding ecosystem.

### Materiality and Sustainability

The materials selected for Casa Macondo embody both ecological and cultural significance. Barichara stone provides foundational stability while offering an earthy aesthetic. Guadua bamboo, known for its strength and flexibility, is utilized throughout the framework. Earth walls made from a clay-straw mixture ensure thermal comfort and represent a commitment to local resources. Innovative components, such as a biodegradable 3D-printed mesh, enhance the structural dynamics, and QuadCore LED insulated roof panels contribute to energy efficiency by integrating greenery into the living environment.

### Spatial Configuration and Water Management

The open-plan design of 25 square meters promotes a fluid spatial experience, eliminating traditional boundaries to foster adaptability. A pulley system for storage maximizes utility and maintains an uncluttered interior aesthetic characterized by warm, natural tones. The project prioritizes water management through systems like rainwater harvesting and wastewater filtration, promoting self-sufficiency and minimizing ecological impact. Unique features, such as a butterfly facade that facilitates natural airflow and light, further enhance the interaction between the interior spaces and the environment.

Casa Macondo exemplifies the integration of high-tech solutions with traditional building methods, incorporating local craftsmanship to reinforce its connection to the regional context. This design approach illustrates a commitment to fostering a sustainable lifestyle while embracing cultural narratives, all within an innovative architectural framework.

`
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.
