What wieNEU-GmbH does

wieNEU GmbH is a privately held German construction company headquartered in Leverkusen, North Rhine-Westphalia, specializing in energy-efficient renovations of existing buildings and sustainable new construction. The company was formally incorporated in 2023 under managing director Daniel Platz and operates with approximately 14 employees, serving homeowners and property owners across the Leverkusen, Leichlingen, Langenfeld, and Solingen areas.

The company's core technology offering is the Thoma Holz100 cross-laminated solid timber construction system, licensed through a partnership with Austrian manufacturer Thoma GmbH. This system uses mechanically connected wood dowels in place of glue, metal, or chemicals to create wall, ceiling, and roof panels with documented fire resistance (REI 120 / F 90), passive house insulation standards, and natural humidity regulation. wieNEU complements Holz100 with natural building materials including clay, straw, hemp, lime, and wood fiber, and applies Cradle to Cradle design principles (per Professor Dr. Michael Braungart) treating buildings as material repositories for end-of-life recovery. A secondary service line is photovoltaic system installation with battery storage using SolarEdge, Huawei, Kostal, and Victron Energy hardware.

Revenue is generated on a project basis through four streams: energy-efficient renovation services, new construction of Massivholz houses and roof extensions, photovoltaic installation, and consultation/planning services. The go-to-market is sales-led and consultation-based, relying on the company website, a blog for content marketing, a Facebook page, and direct customer contact via phone and email. Pricing is custom-quoted per project with no public price list, and the company supports customers in securing energy-efficiency funding and building permits. No public revenue figures, funding rounds, or external investors are disclosed.

Direct peers

• WeberHaus GmbH & Co. KG: One of Germany's largest timber prefabricated home builders with a strong focus on energy-efficient and PlusEnergy houses. Comparable on timber residential construction, energy efficiency emphasis, and German homeowner target segment, though at much larger scale than wieNEU.
• SchwörerHaus KG: German timber prefab house manufacturer producing energy-efficient homes including passive house standard. Comparable to wieNEU on timber new-build construction and energy-efficient German residential market, with broader national reach.
• DFH Haus GmbH: German group of timber prefab house manufacturers (mass timber and timber frame). Comparable on residential timber construction in Germany and similar end-customer (German homeowner) segment.
• Baufritz GmbH: German full-service ecological timber house builder offering prefabricated healthy homes with natural materials, FSC wood, and Ergesund certification. Directly comparable to wieNEU on positioning (eco-timber, natural materials, residential Germany) and overlapping customer segment of health- and sustainability-conscious homeowners.

Others

• pro clima (Moll bauökologische Produkte GmbH): Manufacturer of high-performance weather barriers and airtightness solutions (e.g., INTELLO plus) referenced by wieNEU's own blog content. Functions as an enabling supplier in the ecological timber and renovation value chain, not a direct competitor.

Emerging players

• Enpal GmbH: Leading German residential solar leasing company offering PV systems with battery and heat pumps. Comparable to wieNEU's PV hardware/installation stream and overlapping German homeowner target segment, though at much greater scale and via a leasing model.
• 1Komma5° GmbH: Fast-scaling German energy renovation and electrification company offering PV, heat pumps, EV charging, and dynamic electricity tariffs. Overlaps with wieNEU in the PV installation and "energy-independent home" proposition and on the energy-modernization homeowner segment in Germany.
• Ecoworks GmbH: Berlin-based energy renovation startup using industrialized timber prefab elements for serial deep energy retrofits of multi-family buildings in Germany. Comparable to wieNEU's energy renovation offering and use of natural-mass-timber prefab, but focused on multi-family rather than single-family customers.

Broad incumbents

• Thoma GmbH (THOMA Holz100): Austrian manufacturer and patent holder of the Holz100 cross-laminated solid timber system used by wieNEU. Functions as upstream technology provider rather than direct competitor, but its broader business model and license network define wieNEU's differentiation and the addressable market for the same construction method.
• ZÜBLIN Timber (Ed. Züblin AG): German mass timber engineering and construction arm of the ZÜBLIN/STRABAG group, delivering large-scale timber commercial and residential projects. Comparable as a mass timber construction peer, but operates at significantly larger project scale and with a broader commercial/institutional tilt than wieNEU.
