I am not only impressed with your adherence to your old style of garage and construction, but the marvelous utilization of space.

What a great place to tuck the air compressor – was the concrete pad purpose built or simply fortuitous in its placement and size?
I particularly like the old newels under the railing separating your new-found floor space from the old. What’s your plan for the open space between the railing and the man-door – looks to be about 6 feet wide? Great place to install some pass-through shelving . Of course, that would obscure the flag hanging on the rear wall.
One question and one comment:
Q: Do you worry about fire with such an old wooden floor surrounded by such aged wooden walls? (Maybe I should have started that question with “How much do you worry . . .”.) I noted a few oil/grease stains in the wood flooring and didn’t see a fire extinguisher anywhere in your photos..
C: Glad to see that when you opened the floor plan to incorporate the green house you took the time to properly display Old Glory on your “new” back wall.
