Unfortunately, the reality is this is incorrect. Marriage isn't just some 'label', it's a covenant, or contract. As in the business world, what's said doesn't mean much, it's what the contract says that means something. People get in trouble all the time thinking they have 'rights' without marriage, only to find out the hard way that this is simply not true.
This is not for or against marriage, or for or against dating. But it IS two different levels. First, you have to judge whether this is a whim; if she will actually be doing woodwork long term, or if it's a passing fancy. You're the only one that knows her. If she tends to stick with something, do the minimum; I like the portable building idea. Easy to sell if she flakes out or leaves. If you were married, I would say to still make the same judgement, but if you felt she was serious, do an addition.
I've been with my girlfriend 27 years. Thanks to flaky parents who are still married but hate each other she is terrified of marriage. I made peace with our relationship because I love her and she is literally one of the best people I've ever known. But it's understood that she is in no position to dictate what I do or what she can 'make' me do or give her. If she will someday marry me, THEN she will become half owner of everything I have, and have say in things like what WE would do with OUR shop. Until then, we are two separate entities, not joined as one. Marriage makes all the difference.
Think about the portable building. If needed it can be easily sent down the road, clean and easy.
Just like a girlfriend
