The Bayou House responds to the environmental issues facing Louisiana's coastal areas, where rising sea levels and land loss pose serious risks to local communities. Located in a region anticipated to be underwater by the middle of this century, the design serves as an alternative housing solution for residents. Drawing from the traditional southern shotgun home, it focuses on durability and adaptability. The Bayou House aims to honor the rich culture of the area while addressing contemporary environmental challenges.

Floating Foundation

A key aspect of the Bayou House is its floating structure, supported by repurposed industrial polyethylene drums. This foundation elevates the home above potential floodwaters. By doing so, it allows residents to stay in their community even as sea levels rise. In a state where land is disappearing at alarming rates, this innovative solution addresses a pressing need for safe housing.

Design and Layout

The layout incorporates traditional features like screened-in outdoor porches, which create spaces for living and engaging with nature. These porches not only enhance comfort but also improve ventilation. The design reduces the amount of glass on the facades, which helps to control temperature and make the interior more pleasant in hot, humid weather. This thoughtful approach to layout promotes a balance between indoor and outdoor living.

Interior Features

Inside, the Bayou House uses plywood sheathing for its structural elements. This material is both cost-effective and adds a sense of warmth to the living spaces. Dual skylights allow for abundant natural light, contributing to a bright atmosphere. There is also a window placed near the work area that gives views of the porch garden, further connecting the interior with the outside environment.

Sustainable Systems

The house includes modern ecological features such as photovoltaic panels for generating energy. A composting toilet system helps to reduce water use, aligning the design with sustainable living practices. These components together strive to create a self-sufficient home that lessens reliance on conventional utilities and emphasizes environmental responsibility.

Storage solutions are creatively integrated into the flooring, maximizing space without sacrificing aesthetics. This practical approach enhances the home's functionality, making it suitable for everyday living while preserving its connection to the unique coastal landscape.

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.
