The judgment is based on the combination of all these criteria.
In your scenario, you are the craftman’s direct client, a contract will be signed between you and them, not with some wrapping entity.
If you need additional work on the shed you can call that same person, renegociate a price for the additional job and continue the relationship. Same if you have claims, if you need to cancel the job for any reason for instance. And you can both agree to renegociate the contract under your own terms.
That direct relation is only a part of the whole picture, but I think it’s a significant point.
