Hello... Thank you for asking. The wall cabinet right of the refrigerator was custom built to the size 31 1/2"W x 41"H x 14"D. It was built with more face frame at the top so the crown molding could be applied to the face and still allow the doors to clear it. Here is the lovely before photo. We removed the peninsula to the left, shifted the refrigerator left, and added counter space to the right. Since we lost the peninsula we installed cabinetry across the way where there was none before after removing an unused door. It looks more cohesive and finished now. It is all new now. Hickory floors too!

Also, the microwave opening is 27 1/2"w x 16"H.
