What Klein Groep does
Klein Groep, operating commercially as Klein Units (legal entity Klein Units B.V.), is a Netherlands-based, family-owned provider of modular temporary space solutions. Founded in 1989 by Klaas Klein and headquartered in Staphorst, the company manufactures, rents, and sells portable units across five core product categories: Kantoorunits (temporary offices), Schakelunits (versatile modular units for work and education), Sanitair units (mobile-to-fixed sanitation), Schaftwagens (break/canteen wagons), Woonunits (residential units), and Opslagcontainers (storage containers), supported by an accessory range including steel stairs, fecal and water tanks, safety signage, solar frames, saw sheds, and furniture. Units feature LED lighting, double glazing, electrical ceiling heating, insulation, and PVC flooring, and the company operates under VCA safety certification.
The business operates across five customer verticals: construction, industrial, office, education, and residential/housing. Revenue is generated through four streams: recurring rental (with bundled maintenance), one-time sale of new units sourced from long-standing Czech and Slovenian manufacturing partners, resale of renovated used units, and managed services including transport, installation, permits, insurance, and utilities coordination, plus 24-hour emergency service capability. Distribution is direct via three strategically located branches (Staphorst, Zeewolde, Dordrecht) covering the Netherlands, with an own fleet of crane-equipped trucks for delivery and placement.
The 2014 acquisition of Brouwer Units and Wagenbouw added in-house production capability, transforming the business from a pure trader into a manufacturer with a capital-intensive asset base spanning more than 4 hectares in Staphorst and a workforce of more than 80 employees. The company is privately held under founding-family ownership with no external funding rounds, no public listing, and operates entirely within the Dutch market.
