A hydroponic greenhouse integrates with a compact X-Lam module, creating a self-sufficient living space that emphasizes sustainability and environmental harmony in Balme, Italy.
5 key facts about this project
01
A hydroponic greenhouse provides year-round food production.
02
The building uses specialized assemblable columns for flexible placement.
03
X-Lam construction allows for quick assembly with minimal waste.
04
Renewable energy systems include photovoltaic panels and a wind turbine.
05
The design efficiently maximizes natural light through large windows.

The modular living solution is located in Balme, within Pian della Mussa, Italy, an area known for its rich biodiversity. Designed for professionals, the project draws inspiration from the lunar Lem, built for NASA. It aims to create an independent and environmentally friendly living space that works well with its natural surroundings. The compact design promotes both efficiency and sustainability.

Concept and Structure

The building is prefabricated using X-Lam systems, a construction method that allows for quick assembly and reduces waste. There is no need for extensive foundation work due to specialized assemblable columns that support placement on various surfaces. The interior layout is designed to maximize space, with designated areas for living, sleeping, and working. This organization enhances functionality, making it adaptable to the needs of residents.

Energy Efficiency

Energy efficiency plays a crucial role in the design. Underfloor heating ensures comfort while minimizing energy use. The roof features photovoltaic panels, solar thermal systems, and a wind turbine generator. Together, these elements collect renewable energy, allowing residents to meet their energy needs sustainably.

Materiality and Aesthetics

The exterior design considers both function and visual appeal. Wooden shakes provide a warm look while adding insulation. Stone wool corrugated panels cover the walls, improving energy efficiency and weather resistance. These materials support the project’s focus on sustainability and create a harmonious appearance with the environment.

Sustainable Features

A key feature of the design is the hydroponic greenhouse, which allows residents to grow their own food. This speaks to a larger goal of self-sufficiency. A water management system with ducts transports fresh spring water, while a septic tank manages waste effectively. Together, these elements help reduce the project’s environmental impact.

Large windows in the module invite natural light inside and offer views of the surrounding landscape. This connection to the outdoors enhances the living experience, ensuring that residents feel engaged with their environment.

`
Competition organisers

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. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
