De Prefabriek is a Dutch company founded in 2018 that specializes in prefabricated home extensions, offering families a fast, modular, and sustainable way to expand their living space. Based in Zwanenburg, the company has built its reputation on delivering custom extensions that can be installed in just five days, a timeline made possible by manufacturing modules entirely off‑site. This process eliminates weather delays and ensures precision, while giving homeowners a seamless experience with minimal disruption.

De Prefabriek’s philosophy centers on combining speed with quality. Every extension is designed to meet the latest Dutch building regulations, including the 2024 Bouwbesluit standards, and comes with a ten‑year warranty. By keeping production in‑house, the company maintains full control over materials, design, and assembly, ensuring that each project is tailored to the client’s needs. Their prefab process also reduces CO₂ emissions by up to 26% compared to traditional construction, making sustainability a core part of their identity.

Beyond technical innovation, De Prefabriek positions itself as a lifestyle enabler. Families use its extensions for home offices, creative studios, or extra bedrooms, while the company’s financing options make these upgrades accessible to a wider audience. With showrooms in Amsterdam and Elshout, De Prefabriek has become a visible player in Europe’s growing modular housing market, distinguishing itself with unmatched speed and a customer‑first approach.
