## Overview
The 3D-Printed Passive House is located in [specific location], designed to merge cutting-edge technology with passive architectural principles. The project aims to demonstrate the compatibility of modern 3D printing methods with sustainable construction techniques, while also drawing inspiration from traditional building practices. It addresses the imperative for environmentally responsible design, enhancing the living experience through efficient use of space and resources.

### Spatial Configuration
The architectural layout features staggered massing that creates a distinct form, enhancing both visual appeal and environmental performance. The design incorporates a main facade that balances solid walls and expansive glazed areas to optimize natural light and ventilation. A semi-courtyard serves as a central gathering space, while a sunken garden and pool promote seamless indoor-outdoor connections. Additional elements such as timber balconies and shaded terraces facilitate outdoor enjoyment, offering unobstructed views and contributing to social interaction among residents.

### Material Strategy
The material selection for the project aligns with its sustainability goals. Hollowcore slabs are utilized in the walls through 3D printing, combining efficiency with structural integrity. Precast prestressed concrete elements contribute to a lightweight yet resilient framework. A deliberate choice of wood for balconies complements the outdoor elements sustainably, while glass features enhance daylighting throughout the spaces. Green roof materials employ lighter substrates to support the rooftop garden, further integrating ecological considerations into the design.

Furthermore, the building incorporates both passive and active energy-conserving strategies. The installation of a windcatcher facilitates natural ventilation by harnessing prevailing winds, while the roof garden introduces low-maintenance greenery that enriches the aesthetic and ecological aspects of the environment. Through a holistic approach to comfort and energy efficiency, the design exemplifies advanced architectural practices that prioritize sustainable living.

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.
