Prices of shipping containers are pretty volatile – they rise and fall with the balance of trade (if theres a surplus of contianers entering the country versus ones leaving) and the health of international shipping generally. As they are not so cheap to move about price is also dictated by how many good shipping containers are available locally to you. They are cheap where theres lots of them in your town, expensive if theres only a handful in the county.
If I had a time machine I’d go back to 2011 – buy as many shipping containers as I could get my hands on – then sell them again in 2013 🙂
Price is dependent on condition but also whether something is actually a ‘shipping container’ – ie something made for the purpose of moving round the world of ships and trains and built to that spec or just a similar looking storage container. The former – despite being fairly disposable are very well put together from corten steel, are epoxy coated and very good flooring as they spend months out in the elements at sea and the contents needs not to get ruined. Storage containers are something you keep your wheelbarrows in on a building site – are usually painted mild steel are are much more rot and rust prone and the floors aren’t as good quality or as well sealed – as soon as the floor degrades in any way the container turns into a big smelly box of damp.
£1700 probably is a fair price for a good condition ISO shipping container. £800 is a fair price for a not so new storage container.
