A central column integrates energy-generating photovoltaic glass and rainwater systems within a circular form, optimizing sustainable living in a contemporary residential environment.
5 key facts about this project
01
A central structural column houses essential utilities while supporting the radial design.
02
Photovoltaic glass is integrated into the facade for energy efficiency.
03
Rainwater harvesting systems are seamlessly incorporated into the building structure.
04
A circular layout promotes unobstructed views of the surrounding landscape.
05
Prefabricated components reduce construction time and environmental impact.

### Project Overview

The Ring House, located within a carefully considered landscape, integrates contemporary design with sustainable practices to create a cohesive residential environment. The structure's circular form reflects a commitment to functionality while fostering an intrinsic connection with its surroundings. With an emphasis on energy efficiency and self-sufficiency, the design seeks to unify users with nature and address modern living requirements.

### Design Philosophy and Spatial Organization

The design philosophy centers around the concepts of "funnel" and "diversion," optimizing the flow of rainwater and electricity through the structure. Organized around a central column, the layout promotes a clear spatial hierarchy while facilitating movement and interaction among inhabitants. This radial organization enhances the living experience, allowing for flexible and efficient use of space. The layout strategically delineates functional areas—such as dining, cooking, and sleeping zones—while maximizing access to natural light and ventilation through abundant glazing.

### Material Selection and Sustainability Features

Materiality is central to the Ring House’s design integrity, incorporating a range of thoughtfully selected components that enhance both functionality and aesthetic coherence. Concrete serves as the foundational element, providing stability, while steel plate profiles form the outer shell, balancing strength with a modern appearance. The use of power generation glass integrates photovoltaic cells, enhancing the structure’s energy efficiency. Additionally, galvanized steel fixtures contribute to durability, complementing the residence's natural context. Innovative systems for rainwater collection and energy generation emphasize the project's commitment to sustainability, ensuring operational independence while minimizing environmental impact.

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.
