Spherical forms and intricate light dynamics create an engaging atmosphere within a guest house designed to support both communal interactions and individual privacy.
5 key facts about this project
01
Spherical forms allow for fluid spatial transitions and interactions.
02
Natural light is strategically harnessed to enhance user experience throughout.
03

05
Light diagrams guide the architectural response to environmental conditions.

The design emphasizes the concept of "Negative Air" while creating a setting that merges with the environment. The structure functions primarily as a guest house, aiming to balance private and shared spaces. By focusing on the idea of negative space, the design seeks to create a sense of connection and flow, enhancing the experience for everyone who uses it.

Conceptual Framework

The concept of negative air comes to life through forms that take inspiration from air bubbles. These shapes are depicted in concept photos, serving not just as design elements but also as symbols of connection within the space. This approach challenges traditional boundaries, allowing for a more fluid understanding of how spaces relate to one another.

Spatial Organization

Circulation diagrams illustrate how people will move throughout the building. Pathways are carefully designed to encourage movement between private and communal areas, facilitating interaction among guests while ensuring they also have their own private moments. The organization of spaces is intentional, enriching the experience without sacrificing comfort or privacy.

Light and Material Dynamics

The relationship between light and architecture plays a significant role in the overall design. Light diagrams show how natural sunlight interacts with the various forms, enhancing the atmosphere of each room. This attention to light creates a pleasant experience, making the spaces feel more inviting and warm.

Final Design Details

The finalized plan for the Thermal Hot Springs Guest House presents a clear and functional layout. Sections and elevations highlight important areas, including living spaces and kitchens, arranged thoughtfully to promote interaction. Unique detailing is evident throughout, such as the way light casts intricate patterns as it filters through strategically placed openings. These elements work together to create an engaging environment that supports both social connections and personal reflections.

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.
