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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
