Why is a modular welfare unit essential?
On a construction site, the welfare unit is not just a temporary shelter – it is a temporary modular infrastructure that plays a vital role in ensuring the comfort, safety, and productivity of workers. It must comply with labour regulations, providing sanitary blocks, separate locker rooms, rest areas, and offices.
Habitable modular solutions for the construction industry offer rapid installation, high adaptability, and cost control, whether for short-term or long-term projects.
What is a modular construction site welfare unit?
A modular welfare unit is a set of demountable site structures installed to meet the daily needs of workers. These modules can be placed side by side or stacked, standalone or connected to utilities. They may include modular bungalows, habitable construction site modules, or temporary modular spaces.
The benefits of modular solutions
- Fast installation (from a few hours to 72 hours)
- Mobility between sites
- Full customisation
- Compliance with sanitary and electrical standards
Components of a complete welfare unit
Construction Site Offices
An administrative space for site managers, meetings, and document management. Typically equipped with a desk, storage cabinets, LED lighting, and optional air conditioning.
Site canteen & dining area
A welcoming space for breaks, equipped with tables, chairs, sink, and power outlets. Options for microwave, refrigerator, or a combined office + canteen module are available.
Toilet block & showers
Modules with toilets, washbasins, and shower cabins. Available as self-contained units with tanks or connected to existing networks, depending on site conditions.
Locker rooms & rest areas
Separate spaces for workwear and personal clothing, individual lockers, ventilation, and integrated benches.
The advantages of MT Bungalow modular welfare units
Our construction site welfare unitsare designed for fast, hassle-free deployment. Delivered within 20 to 45 days, they are available pre-assembled or in flat pack form, with guided assembly or turnkey installation according to your needs.
Thanks to their flexible design, you can easily add or remove modules as the project progresses, whether in a densely populated urban area or a remote site.
Each module ensures high comfort and safety levels, with efficient thermal and acoustic insulation, durable interior finishes, and full compliance with NF C 15-100 standards and OPPBTP recommendations.
By choosing purchase over rental, you can achieve a return on investment from the second project, with a reusable welfare unit for multiple sites and no recurring rental costs.

According to workforce size
(in line with OPPBTP standards):
- 1 toilet per 10 people

According to site location:
- Urban area – connection to existing networks recommended
