NOPE ..............you are both INcorrect. The issue lies with the inset door face frame. Those units will fit in a European constructed box that's 24" wide no problem. However the faceframe will take up part of that 24". It's likely a 1" frame in this case. Now that said it can still fit in 24" of width if you're willing to have the unit stick out from the adjacent frames and inset door/drawers , but what would be the point of that? You are also going to need an extra deep cabinet in order to pull off the flush mout application.

melissastar - you are right that there are windows on both sides of the range. I will try to post a diagram soon (need dh's help - I'm actually david_in_mn's wife. :) tracie.erin - the purpose of the 48" is landing space, but also extra work space. We have six children who love to help in the kitchen and I don't want to be stuck to a corner, but have several counter spaces for various people to be prepping different things. This is why I liked the microwave drawer idea - - to free up counter space. Also, I really like the idea of easy access for our kids. I've not thought of the pantry because then I wouldn't have an easy place to set a lid or spoon from what's cooking in the microwave. I'm open to an upper cabinet, but with the windows, I am already limited in upper cabinet space, where I'm planning to put spices, oils, etc. Thanks for the ideas; it helps to brainstorm things that I haven't thought through. I really need to post some diagrams to help the discussion, so I'll hopefully do that soon.

@acm I hadn’t thought about into the sunroom then out the side. That would be easiest, but would mean two bends. I’ll have to look into that. For wall cab plans, If you can make out my very hastily (not to scale) drawing. We have one hanging cabinet planned between our front door and window and an easy reach corner wall cabinet (the kind that wraps around corner, not angled) in the corner next to the range. The picture with the MW on the metal shelf is where that first wall cabinet would be and I agree that is the best spot. I’ve liked it there. It’s very accessible, you have a place to set things when you take them out. Its close to my cooking area but not right in it. This morning I told DH we absolutely could not hang a MW under the corner cabinet. It’s such a bad spot. You can’t actually get in front of things in that corner. I can’t imagine trying to pull hot things out of a MW from to the left or right of it. That does sound dangerous. He has agreed to put it in the wall cabinet that corresponds to where I have it now, but only if it can be inside the cabinet. The cabinets are shaker but he is definitely throwing in some craftsman elements and he really wants to try to get that uniform look that you see in craftsman furniture. This has been really hard because our space is odd and in order to make it work symmetry has had to go out the window. He is wanting to try to make the uppers as uniform as possible. I’ve done lots of sketching trying to figure out how things will work. Here is one when I was trying to imagine how to make the microwave not look completely out of place there above the range ending at the window. I just could not do that to my satisfaction. A hood will not only be more functional but it will look so much nicer in that spot. Here I adjusted a drawing to make the wall cabinet have an open shelf for the MW. He doesn’t like how that it would make our only two wall cabinets no longer match in style, which I get. I’m not super excited about the idea of having to open a door to use the microwave, but I’ll do if I have to. I’ll work on him some more first and see if I can get him to come around to either an open shelf or a built in. GE does have a smallish MW that can be built in or hung and would fit on that shelf and we decided to make them slightly deeper to accommodate a MW more easily. Since our prep areas are under the windows the deeper cabinets won’t affect us. I could hang it under the cabinet but then I’d have to move my coffee pots and I really like them there. @kaseki I hadn't thought to try that, though the MW is currently in a box. I was going to call GE however since its been decided to put the MW in the wall cabinet, no need to figure it out I’ll just sell the MW. Thanks for the tip about wind direction. I’ll keep that in mind.

Nearly all shelf pins are either 5 mm or 1/4". If I'm not sure which size I need, then I buy both sizes from a local store (or order them), see which ones fit, and return all of the ones I don't need. The next question you'll need to answer is what type of shelf pin/clip you need. There are many styles, as shown on this site.
