Three uses, three types of modules
- Tool and equipment storage — 20 or 40 feet dry. Secured against intrusion (Corten steel, lock-box protected padlock). For small tools, generators, bulky materials.
- Site accommodation unit for team — Modules can provide toilets, washing, changing and rest facilities. Assess suitable provision for the workers and site, including usable existing facilities; a separate cabin is not automatically required.
- Administrative base — project manager's office, meeting room, site supervisor. Site bungalow or fitted-out container with windows, insulation, heating.
Welfare facilities on site: what to provide
In the United Kingdom, employers must provide welfare facilities suitable for the workforce, risks and site conditions: toilets, hand washing, drinking water, changing and rest facilities as required locally. Have the design checked by the site safety professional and competent authority.
Changing rooms
Provide changing and storage space for work and personal clothing, suited to contamination risks and the workforce. In a fitted-out container, allow room for about 12–14 people in a 20ft high cube and 20–24 in a 40ft high cube.
Washing facilities
Provide water, soap and hygienic drying for hand washing. Hot water and additional facilities depend on the work and local requirements.
Showers
Assess showers according to dirty work, hazardous substances and prevention measures. Check privacy, water supply and maintenance.
Toilets
Provide accessible, maintained toilets with capacity suited to workforce and local conditions. Check separation or individual use under applicable rules.
Rest and meal area
Provide a clean place for breaks and meals away from site hazards, with a fridge and a means of heating food. In practice, a 20ft canteen unit seats 8–12 and a 40ft unit 16–24.
Framework: CDM 2015 in Great Britain and CDM (Northern Ireland) 2016. Check special cases (mixed workforce, specific work, long duration) with the person responsible for health and safety on the site.
Security on construction sites: anti-theft and anti-intrusion measures
Choose the security level of a site container according to the value of the tools inside, whether the site is guarded and how exposed it is. Four levels, from a standard padlock to mobile CCTV:
Level 1 — Lock + standard padlock
Sufficient for construction sites in guarded areas (human guarding or active surveillance) with less sought-after products. Marine padlock 60-80 mm, shackle diameter of at least 10 mm. Cost: £32 – £84.
Level 2 — Lock-box + anti-cut padlock
The lock-box is a welded steel housing that protects the padlock from bolt cutters and angle grinders. Standard for unguarded urban sites. Lock-box £84 – £210, anti-cut padlock £63 – £158.
Level 3 — GSM alarm + detectors
For high-value tools (generators, top-end portable machines) or isolated rural areas. Alarm with opening and vibration sensors, GSM transmission to site manager. Alarm purchase price £315 – £840 or rental £42 – £84/month. With professional monitoring: £63 – £158/month.
Level 4 — Mobile autonomous video surveillance
Solar-powered mobile CCTV tower with presence detection, flash and siren. For high-risk sites (equipment > £105,000, areas with previous incidents). Rental £315 – £735/month. Often immediate return on investment from the first theft prevented.
Insurance tip: for a long-term construction site, the cost of a GSM alarm + subscription is often lower than the additional professional liability insurance premium due to previous claims history. Request a quote with and without remote monitoring — the difference reveals the true value of the device.
Frequently Asked Questions
Why rent a shipping container instead of a site bungalow for a construction project?+
Three advantages: superior security (Corten steel vs light sheet metal, anti-intrusion), longer lifespan of equipment across multiple sites if purchased, lower cost per cubic metre for pure storage. A site bungalow remains preferable if you need an interior fit-out ready to use (changing room, equipped office). Both can be used on the same construction site.
What is the monthly rental cost for a construction site?+
20 ft dry container (tool and material storage): £40 – £142/month for long-term rental, £70 – £197 for short-term rental. A fitted-out office bungalow: £90 – £228/month. Modular sanitary unit: £141 – £378/month. Excluding delivery (£315 – £630) and connection costs (water, electricity: £525 – £2,625 depending on distance to the network).
How long for delivery to the construction site?+
Delivery timing depends on stock, transport and site access. Confirm the date and charges for your address in writing; urgent service may involve a surcharge. Tell the rental supplier about access restrictions and agree on unloading equipment. Indicative figures to confirm in the quote: £105 – £315.
Can we change containers or add more during construction?+
Adding or exchanging a module depends on stock, access and the contract. Ask about availability, dates and logistics charges before confirming; an exchange is not automatically included. Indicative figures to confirm in the quote: £210 – £420.
Content insurance during rental?+
Most rental contracts DO NOT include content insurance. Your contents (tools, equipment) are covered by your own professional liability or construction site insurance (all-risk construction site insurance). If your insurer does not cover mobile units, subscribe to an extension (£53 – £158/year per module). In case of theft, the procedures and deductible remain your responsibility.
