I think your kitchen will be large enough given you also have the butlers pantry.
However you could perhaps consider extending the length of the island by 300mm giving you more preparation area. Also move the island back towards the kitchen cupboards leaving 1300mm distance between. This will allow you more space around the dining table which currently looks a tad tight to walk around when people are actually seated at the table.
The main photo in the thread has a wall next to the fridge, that is the current plan the one in comments was to show the previous plan with the bigger bedrooms, the draftsman made an error with sizes in the new plan.
I believe the island already has 1.2m between the counter and island. Will clarify that with the builder to ensure there is adequate room
