The tiles are not offensive..most people are choosing white with white anyway. Given the items you want to keep I would simply replace the bench top, add a new wider longer mirror, that fills the space where you currently have the tiles and if you are using laminate it can only be an above mount sink. If you are doing stone or timber then you can have an undercount sink. I would possibly consider taking off all the wall tiles and find a more natural tile to work with your floors and then add a lick of paint to freshen it all.

Paint and more paint paint on floor Move plants away from wall to other side plant near door move as well Paint door a light or bright colour to compliment new wall colour Make steps longer so Go underneath glass panel as well as door Do you use car port Would a bench fit where plants used to be? paint carport support a dark colour so disappear Black works well

What a beautiful room, table is great, I love transparent furniture also it could work well with your room, I can imagine it with your table but a more luxe look could be stainless to blend with benchtops or leather or be brave and mix it up for a more contemporary look, depends on the style you are after, fab room

My suggestion is, removing part of formal dining walls, square off front entry, to give more welcoming space. Extend cabinetry and bench top the full length of space into formal dining space. Maybe with cook top and oven on that new bench. Installing a peninsula or island on meals side of kitchen. Your access from carport with sink, can become the scullery area, as this is not in the sight lines of meals living area. Agree, making the study into a walk in robe, is an easy fix. Without readable dimensions these are just quick suggestions. Also a structural engineer should be consulted regarding which are load bearing walls.
