Not sure if anyone is well up on house valuations here as we are at the very early stages of planning a side extension (2 storey). We're just trying to determine how to divide up the new space downstairs and on the first plans the garage seems to dominate compared to the office.
The current garage is used for bikes,tools and storage. My thinking is to pinch another 3 feet from the garage to make a bigger office. That would turn it into a long workshop with a more normal size door with no ability to store cars. That seems to give me the spaces I want in the house we plan to stay in for a long time, but the wife wound up by her parents is nervous about no garage.
We never have put a car in there and neither does anyone I know in theirs - it seems to be my parents generation that do that. But we don't want to hobble the properties resale potential (no plans to sell).
I can't see that square footage in a garage is worth more than that in an office but would the market demand a garage (4 bed edwardian semi) do you think?
