Re: Is it possible to build it myself?

Yes. You can get standard steel buildings in kit form for self-construction from our suppliers. Kits will come with instructions and drawings but need suitable concrete footings to be laid. To put it up you'll want to have the use of a cherry picker at least and good basic construction skills. If the building is non-standard or you aren't sure quite what you need, you're best off getting the supplier to build it.
