A large cracked sphere with cascading water embodies sustainability through reclaimed materials and engages the community with versatile exhibition and gathering spaces.
5 key facts about this project
01
A cracked exterior allows water to cascade from the spherical structure, creating a dynamic water feature.
02
Locally sourced materials, including reclaimed wood, are integrated into the design for environmental sustainability.
03
The structure features large glass panels that enhance visibility and connect occupants to the surrounding forest.
04
Pathways are designed to follow the natural topography, ensuring minimal disruption to the existing landscape.
05
Biodiversity is promoted through the inclusion of native plants surrounding the building's footprint.

### Project Overview

Located in a forested landscape, the design encompasses a conceptual framework that merges organic forms with functional spaces. The intent is to create an environment that fosters a dialogue between architectural elements and the natural surroundings, employing a design ethos that emphasizes both aesthetic and practical attributes. Central to this plan is a spherical structure that symbolizes the interplay between the earth and sky, providing a visual anchor that reinforces themes of unity and coexistence within the ecological context.

### Spatial Dynamics and User Interaction

The design incorporates a variety of pathways and bridges that facilitate movement while respecting the existing terrain. These elements are crafted to enhance accessibility and encourage exploration around the spherical form, allowing users to engage with diverse viewpoints and experiences within the site. The pathways utilize materials such as steel and reclaimed wood to establish a balance between structural integrity and visual lightness, promoting an unobtrusive presence in the landscape.

### Material Selection and Environmental Considerations

Materiality plays a crucial role in the architectural expression and sustainability of the project. Key components include concrete for foundational stability, steel for structural elements, and glass to enhance transparency and connection with the surrounding environment. The strategic use of reflective water features adds both aesthetic and climatic benefits, contributing to a serene atmosphere while promoting biodiversity through thoughtfully planned landscaping with native plants. This careful selection reflects a commitment to sustainable practices, ensuring minimal environmental impact while enhancing the overall functionality and beauty of the design.

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.
