36" is my recommendation ... mine is 31 and it feels tight (but I still love my new kitchen).

1200mm or 4 feet would be ideal.

Oops! Your trim looks grayish blue to me. Sorry, didn't see it is charcoal until afterwards...well in that case, I think I would still do gable and wrought iron as mentioned but then try a bright yellow, like SW's BEESWAX is paint color. Are you in the islands? Sorta has "that look". Envy : )

With the pantry being located where it is, it provides a opportunity to make it inbuilt and continue your bench top along. This would then provide more bench space and would make sure you are using that wall to its full potential. However for space and flow and to make your kitchen more ascetically pleasing, we would suggest keeping the island bench and making the appliances integrated. This provides opportunity to make that far wall a feature wall, which can be as simple as a blackboard or pictures, to making it a colour feature (depending on you cabinetry) or even to make it high class you could create a wood paneling feature. I hope this helps, either way you can add bonus features to your kitchen, you can create more storage and bench space with changing the pantry, or you could make a design feature out of that wall. It is up to you and where you design flair may take you. Good luck! :) If you would like to see these designs with a quote please call us on 03 423 9067 and we can organise a free one for you. Below are some pictures - in built pantry vs. feature wall. (making where the appliances are a low bench top with below cabinets). (goes beautifully with a black and white colour palette).
