Oh! Using the island counter and the barstool is very smart, as is putting the bathroom access from the deck outside! I love how island counters can do double-duty as both food preparation areas and dining surfaces. I wanted to use them in mine, too, but I couldn't see a way (at the time; thanks to you I now have an idea) to have an island counter *and* enter the bathroom from inside the space.
And, if by "garbage can" you mean one of the small disposal units that need to be emptied every so often, I wouldn't worry about it. It seems much more efficient to me to go straight to a big "all that goes in disappears forever" garbage bin outside. And some lots even come with one just across the pavement, saving you the cost of buying one as well.
