### Overview

Located within a natural landscape, the Ingalls Siblings Wagon project reflects a fusion of historical reference and contemporary architectural form. Inspired by the traditional structure of a wagon, this design symbolizes family unity through its representation of the five Ingalls siblings: Mary, Laura, Carrie, Freddie, and Grace. With an emphasis on enhancing user experience and interaction with the surrounding environment, the design aims to promote connection and exploration.

### Spatial Strategy and Interaction

The circular design of the structure incorporates a dynamic 360-degree perspective, facilitating a continuous engagement with the landscape. Sloped ramps ascend to the main structure, providing visitors with varied viewpoints as they approach. The interior features a pentagonal layout, fostering communal experiences while offering intimate spaces for individual reflection. Surrounding linear concrete benches enhance user interaction, creating areas for gathering and observation while incorporating wooden seating to enrich tactile experiences.

### Material Selection and Sustainability

The materiality of the Ingalls Siblings Wagon prioritizes sustainability and aesthetic appeal. Glu-lam wood, known for its low embodied energy, offers both durability and environmental benefits, while steel profiles reinforce structural integrity where necessary. Concrete is utilized for the benches, grounding the design within its setting, and chain-link fencing ensures safety while maintaining an open feel. This selection of materials underscores a commitment to ecological responsibility, seamlessly integrating the structure within the natural environment.

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.
