That’s a nice looking workshop garage, but every tall tree around it is to be viewed as a potential enemy and really needed to be put on the ground before it was constructed, IMHO
That can't be said enough. Even small ones need to be gone from around structures. They either turn into big enemy trees quicker than you expect, or their roots wreck your concrete work and any drainage, or all of the above.
Over the past 5 years I've brought in a tree crew three times to take down oaks that slowly got out of control under the prior home owner. By the time we came along, the things were 75 feet tall.
