The microhome located near Lake Ontario provides a thoughtful blend of traditional design and modern sustainability practices. Set on an island, this site enhances the connection to the surrounding nature. The design takes inspiration from the wigwams used by historical semi-nomadic communities. It serves the function of year-round living, accommodating the local climate's temperate summers and harsh winters.

Materials and Construction

Locally sourced materials play a key role in the construction of the microhome. The external walls are primarily made of wood, which provides an 8-centimeter thickness for effective thermal insulation. Additional layers include 1 cm of plaster, 3 cm of plasterboard, and 8 cm of goat wool insulation, making the structure both energy-efficient and comfortable. Along with 3 cm of wooden board, there is a 0.5 cm breathable waterproof sheath. A framework of vertical and horizontal strips, measuring 3 cm, supports a roof cover of 7 cm.

Water and Energy Systems

A well-designed water management system is central to the microhome. Water is drawn from the urban aqueduct and is supplemented by a rainwater recycling feature. This system includes a filtering phase to remove impurities, a storage container for collected rainwater, and a pumping mechanism for distribution. A comprehensive piping network ensures that water is readily available throughout the living space, aligning with principles of resource conservation.

Photovoltaic Integration

To enhance energy efficiency, high-efficiency photovoltaic panels are incorporated into the design. These panels feature optimized PERC cells, which significantly reduce current loss and maximize power output under varying conditions. They are made with 3.2 mm tempered glass, providing mechanical durability and transparency. These panels are also designed to withstand high temperatures and potential hail damage, fulfilling the microhome’s energy needs while staying within sustainable practices.

The layout of the microhome offers flexibility for its occupants. It allows for adaptability in how living spaces are utilized and arranged. Natural light and environmental integration are carefully considered, creating a calm interior atmosphere. This focus on the relationship between indoor and outdoor areas enhances the overall living experience, making the architecture feel inviting and connected to the 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.
