Rough stone walls and strategically placed light wells create a dynamic interplay of light and shadow in a residence designed to harmonize with the desert landscape.
5 key facts about this project
01
Rough stone walls integrate seamlessly with the natural landscape.
02
Light wells optimize natural illumination in living spaces.
03
A courtyard with a canvas cover provides shade and protection.
04
Visual blocks maintain privacy while allowing indirect light.
05
The design emphasizes the dynamic play of light and shadow throughout the day.

Caverna Obscura is located near the Grand Canyon in Flagstaff, Arizona. The design focuses on the relationship between light and shadow, taking inspiration from themes in Plato's Allegory of the Cave. It creates an environment that not only serves as a home but also allows residents to connect with the natural surroundings through changing light patterns.

Architectural Concept

The concept of Caverna Obscura is centered around the duality of light and shadow. This design encourages a conversation between these two elements throughout the space. Natural sunlight functions like a sundial, guiding daily routines and activities. Ambient light creates distinct atmospheres in different areas, balancing functionality and visual appeal.

Spatial Configuration

The dwelling features a layout divided into functional zones, such as a kitchen, living room, and private areas. Each of these spaces is enhanced by light wells and skylights, which introduce natural light and fresh air. The kitchen has a main light well and a smaller one behind the cabinets. The living room benefits from a skylight, allowing light to shift dramatically throughout the day.

Material Context

Rough stone walls are a significant material choice in the design. This connects the interior to the nearby landscape, creating a tactile warmth that enhances the experience of living in the space. The contrast between the textured stone and clean architectural lines provides a visual balance, reflecting both the environment and modern design principles.

Design Details

One noteworthy feature is the courtyard, which includes a canvas cover to protect against blowing sand while offering shade. This thoughtful insertion expands indoor living into outdoor space, allowing for relaxation and gatherings in nature. Visual privacy is also carefully planned, utilizing blocks that let in light without compromising seclusion.

The design of Caverna Obscura illustrates a thoughtful balance of light and shadow, where the home serves not just as shelter but as a way for residents to engage with the natural world surrounding them.

`
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.
