My cousin did something like that, he had to move so he bought a lot, built a garage with a second floor, he had his kitchen/livingroom on the ground level. That gave him a place to live in right next to the house he was building. Once the house was finished he moved his stuff and now has a sweet heated garage with loads of storage space on the second floor.

In his case he had to build a temporary wall inside to enclose the garage door because of winters.

As a garage door tech, I have too many questions.

Such as, where is that spring line? Where is the rest of the tracking? Who installed that motor, and why? It looks like it was installed in the last handful of years. It’s also installed in a helluva way, but, given the headroom, I can excuse it, but, without tracking or a spring line, that motor isn’t doing shit… so why is it there? Wtf is going on here?! This is causing a crisis.

So, it turns out, (as someone pointed out) it’s a one piece garage door, I don’t see these where I live due to snow. So, it likely actually works, crisis kinda averted.
