What HDO Groep does
HDO Groep B.V. is a Dutch specialist in prefabricated timber frame construction (houtskeletbouw, HSB) operating from a 10,000 m² factory in Beverwijk, North Holland. The company produces three core product lines: fully finished residential modules (Prefab Woonmodules) that can be linked and stacked up to seven floors; 2D HSB elements (facades, walls, floors, and roofs) delivered to wind-and-water-tight stage; and rooftop additions (Optopping/Dakopbouw, including the 'Haarlem Dakopbouw' sub-brand) supported by a proprietary feasibility analysis methodology called Daksondering. Production is BIM-engineered and executed on computer-controlled machinery, with modules built from 96% biobased materials and designed for >90% dismantlability to support circular reuse.
The business model is project-based B2B sales-led, with revenue recognized on a one-time delivery basis for modules, elements, and construction services. Go-to-market is direct, targeting five primary verticals: municipalities (temporary/permanent housing for refugees, students, and social programs), housing corporations (renovation and expansion of social housing stock), developers (rapid modular construction), contractors (HSB element supply), and architects (BIM-compatible design). Projects are secured through public procurement and direct commercial relationships led by the commercial director and the director of relations & proposition. Since 2012, the company has completed more than 1,000 rooftop addition projects.
The company's operational differentiator is its waterfront factory location, which enables multimodal transport of modules via CEMT-class III vessels directly from the factory quay to construction sites, reducing road congestion and emissions. Strategic partnerships with Madaster (material passports), Cirkelstad (circular economy cooperative), and Wefloat (floating housing) extend the platform into circular documentation standards and water-based residential concepts. HDO Groep is privately held, headquartered in Beverwijk, and serves the Dutch domestic market.
