The project located on Bustard Island, Ontario, balances sustainable design with practical living spaces. It operates completely off-grid, using photovoltaic panels and low-energy electric systems. The building is elevated on helical piers, which helps prevent flooding while respecting the natural landscape. This design focuses on integrating the structure with its environment, emphasizing both durability and environmental responsibility.

Site Response

The elevation of the building allows the landscape to flow naturally beneath it, minimizing any impact on the surrounding ecosystem. The roof of the building is shaped to follow the slope of the land, creating a visual link between the architecture and its natural setting. This attention to the site reflects a modern understanding of how buildings can coexist with nature.

Spatial Organization

The layout includes distinct sections for living, dining, working, and sleeping. This structured organization aids functionality and enhances movement through the home. Different window sizes throughout provide varied views and abundant natural light, strengthening the connection between the indoor and outdoor spaces.

Sustainability Features

Sustainable elements include a rainwater collection system and an electric tankless water heater, which support responsible water use. The heating and cooling are managed by an air-source heat pump, using cleaner energy to lower carbon emissions. Energy from the photovoltaic panels is stored in saltwater batteries, which are recyclable and do not contain toxic materials.

Materiality and Finish

Materials were chosen to support low carbon goals. Vertical wood cladding and insulation corkboard finishes fit the local context while keeping embodied energy low. Structural components like plywood sheathing and helical piers are selected for their efficiency, blending practicality with sustainability.

The design showcases a thoughtful relationship with nature, marked by a roof that aligns with the landscape and large windows that allow sunlight to fill the spaces. This encourages an inviting atmosphere, reinforcing the sense of connection to the outdoor 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.
