Our goal: Get the existing cutout in the brick wall modified to accept a new larger wall oven. We wanted to only go to the right and up, so as not to cause problems with the cabinets and refrigerator.
Specifications from KitchenAid request a cutout 28 1/2" wide by 41 1/4" tall by 23 1/4" deep.
Original cutout was 25" wide, I don't have original height available right here. Our original estimate that we told Portland Chimney was needing to go 6" to the right, but it turned out we only need to go 3 1/2" which should have made the job much easier.
