If you have not already made this kitchen I would like to help, it lacks adequate storage for good pantry space. If you need a lot of fridge space I am not sure that is the best method as it takes up a lot of space. The idea of adding the bench for the kids is a good concept but the high back means the kids can't see you all the time and they will end up on your side of the bench so they can see you. Incorporating space for the kids at the end of the island bench would be more functional for both you in the kitchen and the kids would be able to see you move around and feel a part of things. Also how will they use this space kids don't just sit still they will want a bench or something they can use to draw do homework etc. Colour contract of light and dark always looks good. If you need help call I have a kitchen company called www.louisdivine.com.au. My kitchens are more traditional styles but I can do whatever is required and given the detail used in my kitchens my prices are competitive. P.S white bench tops are not hard to keep clean and they don't date, the nature of the stone itself is easy to clean.

I would paint all the brick everywhere warm white...satin for occasional cleaning. That done I think everything else will look OK because the colours are natural. New doorknobs are always good. You could if you wanted paint all the bench and cupboards white or rich cream as well....MUCH more spacious effect. there is a product you put on first and wait and paint...Hardware will knw...something like PSo

We have dulux whisper white cabinetry and it is lovely soft/warm but I made mistake of using non-tinted ceiling paint and even with bulkhead divide it looks too stark white (or makes cabinetry look too creamy). Since I can't change the cabinetry, I think I will eventually go over ceiling with 1/4 tint whisper white.

Your kitchen is a good size but not huge so I would go with gloss white to match in with your lovely fridge. All white appliances. Light coloured bench top in the grey range. Backsplash, I'd go to tile expo, choose something you love and add some colour behind the stove, the rest of the splashbacks behind the sink etc in white subway tiles. Dark floors as you have chosen, all the walls in the house Dulux Whisper White. This is a great colour to go with everything, i use it all the time in my designs.
