Prefabrication and Modular Construction Drive CREE’s Expansion into Luxembourg.
Founded in 2010 by Hubert Rhomberg, Austria-based CREE has developed a timber-hybrid construction system that’s gaining acceptance across global markets, and more recently has found traction in Luxembourg. Known as the CREE system—an acronym for “Creative Resource and Energy Efficiency”—this approach to modular construction supports sustainable building across multi-residential, commercial, and institutional projects of up to 30 storeys. The system’s combination of prefabricated timber and concrete provides a flexible solution designed to accommodate the demands of high-density, urban building environments.
System Overview and Architectural Flexibility
The CREE system employs a modular framework composed of prefabricated timber-concrete slab panels and glulam columns, forming a structural grid that can adapt to varied design requirements. Each ceiling level is constructed from timber-concrete slabs, typically between 2.5 to 3 metres wide, enabling expansive, open interior layouts that reduce the need for intermediate columns. This flexibility supports a range of floor plans and building types while reducing the volume of structural concrete needed by roughly one-third—a significant factor in reducing the overall carbon footprint of each project.
The system’s façade components are separately mounted to the primary structure, allowing for flexibility in adapting to local climate and aesthetic considerations. By synchronising the assembly of structural columns with pre-mounted façades, CREE’s system accelerates weatherproofing and facilitates earlier interior fit-outs. This streamlined process also avoids traditional scaffolding.

Aligning with Luxembourg’s Sustainable Construction Objectives
In Luxembourg, where green building standards are increasingly shaping construction practices, the CREE system has found alignment with the country’s goals for sustainable urban development. Luxembourg’s government has shown a commitment to promoting prefabricated, low-carbon construction solutions that support urban density without compromising environmental standards.
Paul Shosseler, Director of Sustainable Construction and Circular Economy for Luxembourg, highlighted the nation’s goals: “The Ministry of the Economy is focused on driving sustainable construction, with bio-based materials and optimised logistical systems that lower emissions as central priorities.”
The labour-saving efficiencies of CREE’s prefabricated components are particularly relevant in Luxembourg’s high-cost labour market. By reducing on-site assembly times by up to 40%, the CREE system addresses both environmental and economic considerations, providing a viable alternative to conventional methods. Bruno Renders, CEO of the Luxembourg Council for Economic Development in Construction, pointed to these efficiencies: “Systems that allow for efficient material use and maintain structural integrity without increasing labour intensity are valuable as we move towards sustainable construction.”
Digital Modelling and Project Coordination
Central to CREE’s approach is its use of digital twin modelling, a tool that simulates workflows from design through to on-site assembly. This model enables early-stage coordination among developers, contractors, and manufacturers, facilitating optimised material use and efficient project execution. The integration of digital tools aligns with Luxembourg’s urban planning and smart city initiatives, further reinforcing the system’s suitability for local conditions.
Shosseler remarked on Luxembourg’s commitment to digitalisation in urban planning, noting, “Digital integration supports both our sustainability targets and the efficient use of resources in construction.”
Pathways to Sustainable Urban Development
The timber-hybrid model underpinning the CREE system offers an adaptable approach to sustainable construction by reducing material intensity and incorporating renewable timber into high-rise developments. Prefabrication allows for significant reductions in resource use, carbon output, and construction timelines, making it well-suited to dense urban environments.
