LENZE-LUIG 3-L-PLAN GBR
German SME specializing in building renovation planning, digital construction inspection, and energy-efficient refurbishment across EU research projects.
Their core work
3-L-PLAN is a small German planning and consulting firm specializing in building renovation, energy-efficient refurbishment, and construction quality assurance. Their H2020 project portfolio shows consistent involvement in projects that bridge digital inspection tools (augmented reality, 3D modelling) with practical building renovation workflows. They bring planning expertise to EU consortia focused on making deep renovation of existing buildings faster, cheaper, and more reliable. Based in Menden (North Rhine-Westphalia), they appear to operate as a specialist contributor applying hands-on construction planning knowledge to research-driven innovation projects.
What they specialise in
INSITER focused on augmented reality self-inspection techniques; INCEPTION on 3D semantic modelling — both involve digital tools for assessing building condition.
INCEPTION applied 3D semantic modelling to cultural heritage buildings; INSITER used AR-based inspection, both requiring digital building representation.
INCEPTION specifically addressed inclusive cultural heritage through 3D semantic modelling of historic structures.
How they've shifted over time
All three projects were initiated within a narrow 2014–2016 window, making it difficult to identify a strong directional shift. Early involvement (INSITER, 2014) focused on augmented reality inspection tools for construction and refurbishment, while the later P2Endure project (2016) moved toward industrialized, plug-and-play renovation solutions — suggesting a progression from diagnostic tools toward scalable renovation delivery. The INCEPTION project (2015) represents a lateral move into cultural heritage, likely applying the same building assessment skills to historic structures.
Moving from digital building assessment toward scalable, product-based deep renovation solutions — relevant for anyone working on industrializing Europe's renovation wave.
How they like to work
3-L-PLAN has never coordinated an H2020 project, consistently joining as a participant — typical for a small planning firm contributing domain expertise rather than managing large consortia. Despite their small size, they have built a broad network of 37 unique partners across 13 countries, indicating they are well-connected and trusted as a specialist contributor in multi-national teams. Their involvement in both RIA and IA projects shows comfort operating in both research-oriented and closer-to-market innovation actions.
Despite only three projects, 3-L-PLAN has collaborated with 37 distinct partners across 13 countries, reflecting the large consortium sizes typical of construction and energy-efficiency projects. Their network spans a wide European geography rather than concentrating on a single region.
What sets them apart
3-L-PLAN sits at the intersection of practical building planning and digital construction innovation — a combination that larger engineering firms or pure-research institutes rarely offer from a single small team. As an SME with direct renovation planning experience, they can ground ambitious EU research concepts in real-world construction workflows and constraints. For consortium builders, they offer the credibility of a practitioner who has been through three major EU renovation-tech projects without the overhead of a large corporate partner.
Highlights from their portfolio
- INSITERLargest funding share (€422K) and an innovative combination of augmented reality with construction self-inspection — bridging digital tools and physical building assessment.
- P2EndureFocused on plug-and-play deep renovation products, directly aligned with Europe's Renovation Wave policy agenda and closest to market application (Innovation Action).
