When building the future of sustainable construction, Leko Labs is not just innovating a material—it’s redefining an entire system. Nestled in the Grand Duchy of Luxembourg, this ambitious company combines the timeless virtues of wood with cutting-edge technology to create faster, more robust, and greener construction solutions.
Founded by François, a timber engineering graduate with a lifelong passion for construction, Leko Labs is driven by a bold vision: accelerating the global transition to sustainable housing. Supported by a team of experts and the humour of their dedicated representative for Belgium, Emmanuelle (or “Manu” to his friends), Leko Labs is changing how we think about wood in the built environment.

A System That Saves Resources and Redefines Efficiency
At the heart of Leko Labs' innovation is a patented construction system that maximises the potential of engineered timber while addressing the inefficiencies of traditional building methods.
Key Features of the Leko Labs System:
Resource Efficiency:
60% less wood and 95% less glue than conventional timber solutions.
Intelligent algorithms optimise material use, ensuring no resource is wasted.
Integrated Performance:
Combines structural strength with thermal and acoustic insulation, eliminating the need for separate materials and reducing wall thickness by 40%.
Built-in insulation offers exceptional energy efficiency and comfort.
Carbon Capture and Zero Lifetime Emissions:
Timber construction sequesters carbon during the building’s lifecycle, making it a climate-positive solution.
Proven Strength:
Engineered to withstand 30,000 times its mass, the Leko Labs system can replace virtually all steel and concrete in above-ground structures, including high-rise buildings.
Technology-Driven Construction
Leko Labs takes timber construction to the next level with a combination of generative software design, automation, and prefabrication technologies.
From Digital Models to Reality
Generative Design: Proprietary algorithms optimise every aspect of the design process, from minimising wood usage to enhancing thermal performance.
Digital Twins: Before production begins, each wall is modelled digitally, enabling defect detection and ensuring precision.
The Robot Factory Revolution
Leko Labs’ Robot factory automates the production of prefabricated building components, drastically reducing construction timelines:
One apartment: 6 hours
One home: 1 day
One building (4 storeys, 15 flats): 4 days
Unlike traditional prefabrication methods, Leko Labs’ technology allows for architectural creativity with minimal constraints. Thus, designers can realise ambitious projects without compromising on sustainability.
The Green Superstructure: A Wooden Alternative to Steel and Concrete
Leko Labs’ Advanced Composite Structure represents a paradigm shift in construction. By replacing steel and concrete with engineered timber, their system:
Reduces embodied carbon, significantly lowering the environmental footprint of construction.
Enhances thermal and acoustic properties, creating buildings that are not only durable but also comfortable and energy-efficient.
The system is ideal for urban environments, where space efficiency and sustainability are critical. Its thin yet strong walls allow for more usable interior space, addressing the challenges of dense, high-rise construction without sacrificing performance.
A Visionary Founder and a Dedicated Team
The driving force behind Leko Labs is François, whose childhood fascination with construction has evolved into a mission to transform the industry. With a background in timber engineering and experience as a partner in a Parisian architecture firm, François has combined deep expertise with an entrepreneurial spirit.
Since founding Leko Labs, François has led the company through multiple funding rounds, securing the resources needed to develop and patent its groundbreaking technology. His leadership, supported by a "bold A-players » team, has propelled Leko Labs from an ambitious startup to a critical player in the global push for sustainable housing.
Closer to home, Emmanuelle, their representative for Belgium, ensures that Leko Labs’ solutions are accessible to the “plat pays.” And if you’re not yet convinced that wood is the future, Manu’s legendary humour might change your mind—or at least leave you laughing!
Building the Future Together
Leko Labs is more than a company; it’s a movement to redefine how we build. By merging the timeless qualities of wood with state-of-the-art technology, they offer a construction system that:
Saves resources without sacrificing performance.
Captures carbon and creates climate-positive buildings.
Delivers faster, more efficient construction with uncompromised design freedom.
As we face urgent challenges like climate change and urbanisation, Leko Labs’ solutions demonstrate what’s possible when innovation meets sustainability. Whether for high-rise apartments or single-family homes, their advanced timber system paves the way for a greener, brighter future.
If you’re planning your next project, Leko Labs invites you to imagine what’s possible with wood—and with the right team, technology, and vision behind it.
