Thank you all for your advice/feedback. We have opted to have a display cupboard built in the same colour as the other kitchen cupboard but with glass doors and half the depth. We loved the recessed/niche walls so having them built in to the hallway walls to make the kitchen/living room area appear slightly bigger plus they will look gorgeous haha! I will post pics in a couple of weeks once they have been installed.

Emulsion is a water based paint that you use on your walls but you can use it on furniture if you sand and prep properly. I use it on pieces that need a reasonably tough finish but you need to sand it to get an interesting finish.

You could just get laminate trims. however they will look newer than the doors so you could replace both or do the trims in a contrast colour.

Is it a wood laminate , or formica or those plastics ? Some will paint up better than others . POSSIBLY , painting the cabinets themselves in a white , but leaving the doors as they are , may work -- theres too much wood look there . And I'd redo the tiles -- even if redoing in 5 years , I'd spend the $500 or less and redo , regrout , etc . Possibly try removing the grout and re-doing in white for a more modern look , but only from a distance haha -- personally I'd go for full tile replacement .
