What Green Box A/S does
Green Box A/S is a Danish manufacturer of prefabricated bathroom modules, founded in 2014 and headquartered in Aulum, Denmark. The company develops and produces complete bathroom units in a proprietary lightweight steel cassette construction (hot-dip galvanized steel cassettes clad with large-format gypsum fiber boards, combined with a reduced concrete floor layer) under controlled factory conditions. Standard modules weigh 325 kg/m\u00b2 with installation heights as low as 95 mm, and every unit carries a unique QR code providing full traceability of drawings, component lists, and quality records. Green Box is the only producer of lightweight prefabricated bathrooms in Denmark holding a Teknisk Godkendelse til Anvendelse (TGA), with materials aligned to Svanem\u00e6rket, DGNB, and BREEAM certification schemes, and an internally third-party verified LCA footprint of approximately 2.9 kg CO\u2082/m\u00b2/year.
The company's business model is direct enterprise sales of physical bathroom modules to construction industry buyers — developers (bygherrer), general contractors (entrepren\u00f8rer), and architects — across Scandinavia and Iceland, supported by a geographically organized sales team (Denmark, Norway, Sweden). Pricing is project-specific with multi-year contracts negotiated on specifications, quantity, and customization requirements; no public list pricing is disclosed. Production capacity stands at approximately 4,000 bathrooms per year at the expanded Aulum facility, with additional expansion phases underway following a June 2025 leadership change. Green Box has been part of the A/S Motortramp conglomerate as a majority-owned subsidiary since 2021 and employs approximately 150 people.
Green Box serves four primary customer segments — developers, contractors, and architects (all primary, business-unit segments), plus hotels, student/youth housing, and care facilities (use-case segments). Notable enterprise customers include the Kaktust\u00e5rnene project in Copenhagen (495 units for Catella Group/H\u00f8pfner A/S with BIG-designed trapezoidal geometry), the Scandic Vervet hotel in Troms\u00f8 (305 units for Totaleiendom AS), and Hotel Jungmannen in Kalmar (197 units for LW Fastigheter/Strawberry). Recurring partnerships with major Nordic contractors such as Backe (Norway) and Nordstern indicate an established repeat-order book. The company has earned multiple recognitions including two B\u00f8rsen Gazelle awards (2019, 2020), the 2022 B\u00f8rsen B\u00e6redygtig Case award, and consecutive ESG Prize nominations (2024).
