What De Prefabriek does
De Prefabriek BV is a privately held Dutch construction company that designs, manufactures, and installs prefabricated home extensions for Dutch homeowners. The company operates an integrated factory-to-site model in which each extension is built in a controlled workshop environment and then transported and installed at the customer's home within a stated five working days. Core technical specifications include a prefab insulated floor (Rc 4.5 m²K/W), insulated walls (Rc 5.25 m²K/W), and a roof with minimum Rc 6.3 m²K/W; foundations use steel piles by default and screw piles where soil risk is suspected, with a dilatation joint between extension and main building.
The product portfolio is built around the "Aanbouw" (extension) platform and extends into living conservatories and garden rooms, care units and caregiver residences, freestanding units, kitchen and utility room extensions, bedroom/bathroom extensions, and add-on modules such as skylights, glass roofs, sliding doors, green roofs, and bay windows. Customer-facing sales is hybrid: a 24/7 online configurator that delivers real-time cost transparency is paired with two physical showrooms (Amsterdam/Zwanenburg and Oisterwijk) and an on-site measurement visit that converts designs into formal quotes.
The business model is direct-to-consumer, project-based, one-time revenue with no subscription or recurring component. Pricing is per project at roughly €3,000-€4,000 per m² plus option-specific add-ons (e.g., light streets €3,500-€7,000), with free quotes issued within one business day and a 10-year structural warranty on every installation. The company sells nationwide through 40+ city-specific landing pages, organic social, paid search, showrooms, and an on-site sales visit step, and reports 1,550+ completed projects at a 4.8/5 average rating across 413 reviews.
