When looking to build a shipping container home be aware that some skills are needed and if you haven’t got them its worth getting someone else in to cover the bits you don’t know. For example I can do electrical,heating,cooling,carpentry and joinery but welding isn’t something I have had to utilize in my construction work before because generally we build with brick in the UK. At the same time if needed I would be willing to spend time learning if need be. You have to remember this is your home your building and not just a weekend project. If done wrong it could be a disaster and a project that has to be rebuilt. I would always advise taking advice from professionals at the same time there are things you can do to make life easier such as buying the shipping containers “pre cut” at the dockside to save you time and also to make sure the holes are the right size and in the right place. If they make a mistake its their problem they have to put right not yours.
