Different kitchen companies use different suppliers. Be it door panels to draw runners. Have a chat to a kitchen company or two that you're thinking of using. Some companies have budget standard hinges and runners as well as high end stuff. Decide on the quality standard rather than branding. Blum have high end and bog standard components for every budget. Polytec make door panels but not sure on the 'shaker' style. Laminex Industries also make panels, again not sure if they make a 'shaker' style.

Painting over cabinet doors can be tricky, depending on what material you're painting over. An easier alternative is just to replace the doors and drawers, and you can do this very cost-effectively by going for a plain melamine colour like this: If you have open cabinets instead of open shelves, it helps to keep the dust off but they still look great. Or you could go for wall cabinets either side like this:

Hi Sue, I think it would look amazing if you used some tiles with a bit of texture. The wood look tiles that are popular at the moment would be an example. If you chose a colour that toned in with your floor you would get a really nice cohesive look but with a bit of interest. I've attached a photo of a recent design of mine as an example. Just a suggestion!

Thanks for all the comments, its great to get the feedback. The apartment is really small and actually very narrow in the kitchen space being only against the one wall. The dark wood makes the room feel smaller and almost pulls the ceiling down lower than it is... To be honest I never really liked it! I am conscious we have bought a lot of American Oak wood scandi style furniture from Icon by Design to fit out the place and it may be overkill going with more timber in such a small area... after getting 4 quotes, I have found it is cheaper in Sydney to buy new doors and have manufactured than to repaint existing doors thats why I thought I could have them all replaced and go handleless We are putting a very small open shelf to the right of the range hood where the existing shelf is, this will be coloured in lighter oak timber veneer to break up the top row colour block.. We decided on the wall/ceiling colours from the beginning and now just trying to work through our kitchen, we found a circuit with easy access to install an LED light strip today which was great, but am now considering whether we put in a glass door to break it up etc. It's so hard to decide!
