Weatherhaven’s MECC combines an ISO container with an expandable shelter to provide roughly three times its packed floor area. Power, HVAC, furnishings and interconnections can be integrated for transportable workspaces; standard, shorter and enhanced-height versions are separate configurations. The company reports delivering two MECC workshop and additive-manufacturing shelters to an unnamed US client in October 2025.

Evidence of maturity
An established commercial shelter family with a company-reported two-unit delivery in October 2025. The announcement does not consistently establish printer installation, so functioning additive-manufacturing equipment is not claimed. DND’s HQSS record is a separate company-level reference.
Commercial availability
MECC variants and integrated fit-outs are offered. Transport certification, setup conditions, utilities and installed equipment must be agreed for the exact delivered configuration.

Weatherhaven reports October 2025 delivery of two 20-foot MECC units for an unnamed US client, configured as a workshop and additive-manufacturing environment. The text is inconsistent about whether printers were already installed; delivery of the shelters is supported, but printer installation and operating performance remain unconfirmed.

DND documents the 2017 Weatherhaven Headquarters Shelter System award and equipment deliveries beginning in 2019. This is an independent historical company-level customer reference, not evidence that the entire HQSS contract consists of MECC units.
The MECC is documented as a self-contained expandable shelter with an ISO shipping footprint, ISO and CSC transport certification, three times the packed floor space, and electrical, mechanical, HVAC, furnishing, and role-specific fit-out options.
