Looks good. I would like to make an alternative suggestion for the office layout. I'd do it in your plan, but I'm currently logged into a different system, so can't access SH3D at the moment. Instead I'll explain:
First, do you really need a door between the office and garage? Seems like a waste of useful wall space. Either way, have you considered putting each workstation on each side of the room, central on their respective walls. The seating position could be offset, so chairs shouldn't clash. Put the bookcase on the wall next to the door to the hall. You could then put a reading/social chair next to the bookcase, and one at the other end. Alternatively how about a 2-seater sofa at the end? (Assuming you lose the door to the garage.) Or, keep the door to the garage, and put a second reading chair there instead like in your image.
Here's a basic diagram, although completely not accurate or to scale
