Personally I would always go for a consistent style throughout the house if at all possible. Expensive if you have to make a lot of changes to achieve it. I guess it comes down to how much it bothers you.

Our local locksmith has lots of quality handles on display. You could visit yours if it’s open.

Try Gainsborough handles, or Zanda. These may not be made in Italy, but are still of good quality and will still open and close your doors.

I , as often seems the case , look at things differently . The cupboards look pleasant , and I gather you want to keep them -- without knowing their condition , I would too . The wooden window sill and door surround are great too , as is the floor . Nothing wrong with the stove and hood either ( can't see enough of the hood so I might be wrong there haha ) . I could live with the taps and the sink ( it has character ) . The tap I categorise the same . I'm sort of in-the-middle about the dishwasher and fridge -- the white doesn't quite work with the stove and even the cupboard colour . Ideally , I'd replace , but I wouldn't get too upset if I had to keep them , at least for a couple of years . So my 'don't like' list is the benchtop , cupboard handles , and the tiles . A couple of others have beaten me to it , but I'd go wood for the benchtop , OR marble or a good marble effect -- offwhites with grey and charcoal streaks . I'll let you make that choice haha . BUT I'd use the sink and tap , as I consider it ties in with the stove . So that leaves the cupboard door handles , and I'd go brass , probably antiqued brass ( darker ) but not an old style with scrolls or stuff -- modern , but as dark brown as I could get . Tiles -- probably those strip ones you get , with narrow charcoal slightly sparkly parts , silvery parts , brushed stainless parts , with a grey grout . The power point on the right I'd revert back to brass plate/surround . If I could , change the fridge and dishwasher to brushed stainless too . So you have wood , darker brown handles , the light cream , stainless , more wood , more stainless , and maybe a greyish marble or more wood .
