Thanks everyone for your suggestions. I am amazed at the response! I think we will go ahead and change the benchtops, replace the cooktop with stainless steel, a new rangehood, splashbacks and new door and drawer handles and possibly a new sink and taps. We will consider painting the beam and post and add a modern blind to the window. Then if we are still not happy, maybe we can rethink the painting of the cupboards? Actually, I like the timber, so if these changes work I will be more than happy to leave them as they are. Our floor tiles are relatively new and are throughout the entire downstairs area. Also, the wall paint we know is not the right tone (for the floor tiles) but is in good nick and will be remaining until we are ready to repaint. Rome wasn't built in a day but I will add photos when we start the process and you can follow our progress. Thanks again

What did you decide? Thinking of Whisper White cabinet but worried it might be appear creamy Against the Grey vein in the benchtop

Use water based enamel paint. It’s the oil based paints that turn yellow.
