In this project, there was an odd peninsula cutting the kitchen right in half, with the work side of the kitchen (stove, fridge sink) on the side where all the doorways were, so basically, LOTS of traffic streaming right through the middle of the main work zone!
We gutted the entire space, but kept the door (at the left of the new fridge location), which is a second stairway to the bedrooms.
The access from the kitchen into the sunroom was changed from a swing door to a patio door.
The peninsula was nixed in favour of a long island that keeps the cook(s) on one side, and the traffic and guests on the other, safely out of the cook's way!
You can see more of this space, entitled "Westmount Kitchen" in our Houzz projects!
