I like the idea of the micro-wave in the corner making it so available to use by sink, stove. I personally would not build in on top of precious counter space. I would elevate it to where hung-cabinet height. If there is a way to do that and somehow have a small smart tv at convenient height...would be ideal in my opinion. You could watch tv, look at a recipe, communicate or....
Also....I personally think that angling the bottom counter at a 45 degrees also eats us some precious storage space. You can still angle the counter-top for that look...however I would think that I would put a carousel in the bottom corner cabinet. This is only my thought though.
