Changing a converted garage back to a garage

[David Sray]

Morning BP!

Was looking at a listing today and it's a small SFH that has a garage that was converted into a workshop-thing. The inside mostly still looks like a garage, but it's got like sliding patio door-thing where the garage door used to be. Anyone have experience putting a garage back-in on a property that previously converted it? This added space doesn't look like it provides much value because it's not particularly nice. Wondering if the cost to make it a garage again (i.e. tear that wall out and put in a garage door, is prohibitive.
