Modular Site Welfare Units
Welfare is about capacity at break times. A unit that works for eight operatives does not work for thirty. We size the canteen seating, the drying area and the number of WCs around your peak headcount, then build them into linked modules.

Hire Site Welfare Units in the UK
Need site welfare units for a fixed period? Hire it instead of buying. Adacon manufactures the building to your layout and hands it over on hire terms, then collects it when you no longer need it — with the same quality, fit-out and design freedom as a purchase.
Hire terms are flexible — tell us how long you need the unit and we will confirm the rate for that period.

Sized around peak headcount, not average
The layout separates dirty and clean routes: boots and wet gear come off in the drying area, washing comes next, and the canteen sits beyond that. This keeps the eating area usable and cuts cleaning time.
- Canteen seating sized to the number of operatives on shift
- Drying area with hanging space and heating
- Hand-wash and WC provision separated from the eating area
- Boiling water and food-heating provision in the canteen module
- Lockers and changing space where required
- Linked modules so office, canteen and WC arrive as one set

What's available for a site welfare unit
Welfare provision on construction sites is governed by CDM requirements. We build to the specification agreed with you; responsibility for site compliance remains with the principal contractor.
