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 Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization.
