FAQs

What facilities are included in modular welfare units for construction sites?

Modular welfare units typically include toilets, showers, hand-wash basins, changing rooms, and secure lockers. They can also be fitted with kitchenettes, canteens, staff rest areas, drying rooms, and storage areas, providing everything required to meet HSE site welfare standards. Layouts are flexible, so facilities can be tailored to the size of your workforce and the needs of your project.

Can modular site offices and welfare units be relocated or expanded as projects change?

Yes, modular site offices and welfare units can be relocated or expanded to adapt as your project evolves. Designed to be portable and flexible, they can be moved between sites or reconfigured to provide extra space as teams grow. As part of our aftercare service, we offer relocation support. Speak to our team to discuss future relocation or expansion options for your site.

How quickly can modular offices and welfare units be delivered and installed on-site?

Modular offices and welfare units can usually be delivered within weeks and installed on-site in just a few days. The exact timescale depends on the size and specification of the buildings required – a single welfare cabin can be operational very quickly, while larger multi-storey office blocks may take longer to manufacture and install. Because most of the work happens off-site, the installation process causes minimal disruption and helps projects stay on schedule.
