Are flat pack office units suitable for long-term use?

Yes, our flat pack office cabins are manufactured from fully galvanised steel to prevent rust and are supplied with a 5-year guarantee. They are durable enough for long-term use, provided they are assembled correctly on a level base and maintained in line with normal good practice. Many customers use them as semi-permanent offices on construction sites, business parks, and remote locations where a permanent building isn’t practical. 

However, if you require a more permanent office solution designed to last 25 years or more, our modular office buildings may be a better fit.  

How long does it take to assemble a flat pack office cabin?

A flat pack office cabin can usually be assembled in under an hour, provided the ground is hard and level. Assembly requires more than one person, as the panels and framework need to be lifted and secured safely. No specialist tools or heavy machinery are needed, making installation straightforward and cost-effective. 

Where can flat pack office cabins be delivered in Great Britain?

We deliver our flat pack office units across Great Britain, including England, Scotland, and Wales. Because they are delivered flat packed, they can reach restricted or hard-to-access sites such as narrow passageways, alleys, or elevated levels where a pre-built cabin could not be installed. This makes them a flexible option for both urban and rural projects.

Shazia was helpful from my first enquiry to the delivery of my container. She sorted any query and enabled me to buy exactly what I was looking for. The driver who delivered container was also a credit to his company. Nothing was too much trouble and everything done with a smile .
