The plan measurements for your current kitchen show as 16’3” x 12’ which do not seem accurate given the measurements for the adjoining foyer and kitchen. Your post’s measurement of 12’ x 10’ seems more accurate but you may want to re-measure to confirm.

Flipping the kitchen and dining room to give more square footage to the more-often used kitchen makes sense.

If you will be in this house long term, consider expanding your re-design to incorporate the mudroom, breakfast room and refrigerator alcove. Perhaps bump those out to eliminate the exterior jogs. That entire area is a lot of space for a great kitchen and dining room (that can also be used for breakfast) that can be larger than 12’ x 10’. Also consider widening the opening into the dining room to accommodate times when you need to expand seating comfortably for more people.

Also look at your traffic paths from garage into the house and from the backyard into the kitchen/living room/family room to be sure they are placed in a way that maximizes flow, usable interior space and accessibility to outdoor spaces.

You are correct, the kitchen is 12x10. The realtor floorplan double counts the space in front of the fridge. The drawing is also not to scale. The breakfast nook will be a pantry/mudroom. The wall between kitchen and fridge alcove/breakfast nook will be closed off and a door added into that are in the new kitchen.

Consider posting a floor plan of the proposed new layout (even hand drawn is fine) so we can better see what you are envisioning. Where will the dining room openings be located? Where will the garage entry into the area be located?

If you bump out the existing breakfast room, you could use that enlarged space for the pantry and mudroom. If you relocate and bump out the existing mudroom, you could have a much larger dining room.

Does this area need to include a laundry area?

The breakfast nook/mudroom/fridge alcove will be a pantry/mudroom and the entrance to the kitchen would be through there. We would close off the current kitchen opening. Here is a rough sketch of what I think the layout of the new kitchen would be. I suppose we could move the current dining room/kitchen door to the middle of the wall. That could make more sense.

What is your living room set up? Could you add the dining table to that space? (28x14 seems large?). I think keeping 3' from table to wall (or table to next piece of furniture) allows for enough space to move around the table (so no larger than 48x72 with no other furniture in the room).

Consider stealing a couple feet from the living room to make the new kitchen larger and to move the refrigerator into the kitchen. Any idea if the wall between the living room and kitchen is load bearing?

Bump out the existing mudroom exterior wall and add the old mudroom space to the new dining room. This will give you a larger rectangular-shaped dining room.
