I would insulate it wth Albanians, shipping containers often come with a free pack of them
How are you getting on?
i really think you need to go stand in a shipping container in the summer
the heat is outrageous , guys at work pass out in them and a mate severly burnt his arm after accidentally touching the sides
air con is going to cost your big and the air inside will be pretty horrid because of its constant use
even today in march with just a bit of sun they are getting sauna like
the prices are just going to rise and rise too along with the prices of scrap
why not go wood ?
You may not even need planning
