Clestra Hauserman

What Clestra Hauserman does

Clestra (formerly Clestra Hauserman), headquartered in Strasbourg, France, is a 1913-founded industrial construction firm that designs, manufactures, and installs modular prefabricated building systems. The company operates two sub-brands: Clestra Hauserman, which provides modular partitions, doors, movable walls, acoustic pods, and customization for tertiary workspaces such as offices, universities, and laboratories; and Clestra Cleanroom, which delivers partitions, ceilings, doors, and bespoke modular solutions for pharmaceutical and biotechnology cleanrooms. Underlying technology centers on factory-based prefabrication — components are built in controlled environments and assembled on-site — yielding cost transparency, schedule certainty, and reduced lifecycle impact compared with traditional construction.

The business operates a project-based, one-time-revenue model: enterprise clients commission custom solutions and receive a tailored quote; no public pricing exists. Go-to-market is direct enterprise field sales with consultative engagement from design through installation, supported by content marketing (blog, brochures, newsletter) and a bottom-of-funnel contact form for project inquiries. Customer concentration sits in two primary verticals — tertiary workspaces and pharmaceutical/biotech cleanrooms — with end users typically being large organizations that require specialized, standards-compliant environments. The company claims worldwide service and maintains a multilingual website (French, English, German, Spanish, Chinese, Japanese, Korean), though no international offices are disclosed. Clestra is privately held with no disclosed parent, institutional, or PE ownership; headcount is reported at 501–1,000 employees.
