I agree with most of the points but a stainless steel dishwasher and stainless steel wide fridge feeezer look fab and much better than integrated. But thats only my opinion.
But granite or stone/quartz composite, wood or tiled flooring etc all look great.
Good lighting and unusual/well thought out ceiling lights not just 3 globes above an island type affair.
I think too many people spend a fortune on their kitchen then forget the plugs and radiators, so a radiator that matches the room and non cheap white plugs are things i notice. Plugs could be stainless steel or nickel or white if on a white wall but if white then go for flat ones, they are more stylish.
Hate the trend for flooring laid on the diagonal and i think it cheapens the space as it jars the lines that the eye notices.
Many kitchens can look expensive simply with good fitting, a good declutter and great lighting.
My own personal tip is dont get a black granite floor, looks great and expensive but nightmare to keep clean as shows every speck and is so high shine, never again.
