there is limited backsplash... one side of the gallery is a bank cupboards.. the side with counter top is open to family room or windows to outside deck and small return which is wall...I am thinking of keep that with white tiles ... also replacing sink with white glass double ...and new chrome fitting for taps and water filter...

My son used to help me cook in the kitchen - he is 190 cm, I am 175cm. I have an old-fashioned breakfast bar which is raised above the level of the kitchen benchtop. My son would stand at the raised section, I would stand at the lower section, it worked really well. An alternative might be to have a pull out step in the kick board spaces for your wife to stand on - I don't know if it would be high enough, but it might make things more comfortable. Speaking from the point of view of a tall woman, I will have my next kitchen cupboards and laundry raised at least 10 cm to make my life more comfortable - bending forward for any length of time is seriously UN comfortable!

Have you considered just using stainless steel sheet. I have done this in three properties. It looks good and is relatively cheap. I have details of a supplier that I have used in each case if you need it.

Kitchens are the heart of s home. You need breakfast stools at your bench so people can chat to you whilst prepping/cooking. Or kids helping or eating brekkie. tables are lower so don’t work as well. It’s not about the view for these purposes. 4 stools at least with backs hopefully and allow them to tuck under bench top to clear circulation to sliders. I would keep all within current footprint. Island: min 900 (at ends) & 1200 from other benches. If u go too wide it makes it more difficult to work. Too many steps. I can stand next to my dishwasher and unload into drawers opposte without moving with 1200. And can work on island whilst someone at sink behind Up to 1500 from sliders if having stools there. Love to see finished pics I like your style. Good luck
