I think the shelves would be better as there's not this huge room taking up space. What did you end up doing?

Possible suggestions if sticking to same floor plan and hands firmly glued to the budget Leave the stove where it is. Down the side of the stove securely attach slimline fireproof panelling to the height of the oven's back control panel and the depth of the oven. Floor to ceiling if you prefer then if you wanted to you could change out the door itself, that is put the door handle to the right of the door so it swings back flush with the fireproof panelling. Put the dishwasher under the stainless steel bench top left of the sink. Take all the cabinetry out where the dishwasher is currently housed place the fridge in the centre of that wall building functional cabinetry around it. Get rid of the cupboard at the end of the stainless steel bench replace it with a wheeled butchers block the same width and depth of bench also have hinged sides so you can get extra useable bench top surfacing. You could then wheel it around include brakes on it of course so little hands don't go racing around with it.

Our clients were a young couple with a growing family, who wanted to modernise their home and incorporate the kitchen with the outside entertaining area, to create more of an indoor-outdoor flow. They had their own builder and contractors who removed the wall but hired All About Kitchens to work with them to design the kitchen of their dreams. Before: We created a sleek handless kitchen, with push to open bottom drawers, an integrated dishwasher, black stainless steel sinks and gooseneck taps, and negative detail 20mm Caesar Stone benchtop. They had visited our showroom in Petone, where they were inspired by a similar display but with integrated lighting. After: They liked the idea of breaking up the kitchen colour by adding the woodgrain look and have incorporated pull-out fittings in the corner for ease of access, oil pull near the stove, and built-in bin units. Their preference was drawers over cupboards, and to fully utilise the drawer height we used internal drawers for cutlery and utensils. After: They required a large walk-in pantry with a sliding door that would also house the microwave. These clients have been great to work with and have been very patient with some of the supply delays due to Covid. They are so happy with the final result and it's such a timeless design that they can enjoy it for a lifetime. Check out the entire projecthere!

I did a black sink like your second pic, but I have Formica and this way I can use the drainer for air fryer (with a board under, just in case!), dirty dishes before using Dw, etc. if I had stone, may not have had a drainer.
