## Overview

The Home of Moonlight is situated in the Atacama Desert, Chile, and is specifically designed for astronomers. The architectural concept is informed by the phases of the moon, emphasizing the interaction of light and shadow, which defines the spatial experience within the structure. This project seeks to create a harmonious relationship between the dwelling and its celestial context, integrating the shifting qualities of natural light into its design.

## Materiality and Environmental Integration

The project employs a selection of materials that reflect both the functionality needed for durability and the aesthetic qualities suited to the surrounding landscape. Concrete serves as the primary structural element, offering resilience, while glass is utilized to maximize transparency and natural illumination, providing expansive views of the night sky. Natural stone is incorporated into the exterior walls, reinforcing the building's connection to its desert environment, while steel provides essential structural support. Wood elements enhance the interiors, adding warmth and a tactile quality. The careful balance of these materials is intended to harmonize the home with its challenging climate while creating inviting spaces for the residents.

## Spatial Strategy and User Experience

The design promotes interaction and exploration through its spatial organization, with a central axis that guides movement from communal areas to private quarters. The layout encourages fluidity and flexibility, fostering community engagement among inhabitants. Curvilinear walls create a soft transition between indoor and outdoor spaces, further enhancing the connection to the environment. Strategic placement of windows facilitates the reflection and absorption of light, creating varied atmospheres throughout the day and allowing for a dynamic sensory experience. Dedicated areas for astronomical observation underscore the building’s focus on celestial studies, defining its unique purpose within residential architecture.

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.
