My recommendation would be to sand back the timber and re-stain in a burgundy or black lacquer. Remove the current curved benchtop with one with squared edges. Replace knobs with modern handles. Replace wooden shelving with glass shelving and behind the shelving on the back panel create a feature but covering in wallpaper. Please feel free to contact me if you would like a quote for a design concept.

i noticed you have a french style clock there, if thats something you like then id stick to a more traditional style.

i'm glad you're planning to reroute access to the garage: clumsy traffic pattern change a generous room into a big hallway and can't stop thinking about your kitchen..1. where you have narrow cabinets/shelves in the pantry...it's possible to have built in shelves inside the dividing wall (think about the size of what you want to store: cans, bottles, skinny packets? and put 60cm base cabinets on the other side, next to the freezer 2. i can't see the yellow highlights for stools 3. width of pantry is subject to you wanting to keep the door to the formal living room...if so, measure 150mm past the door opening and that's the minimum width of the pantry but 1500mm allows space to comfortably walk past your freezer and have full size base cabinets with pantry drawers (cleaner than open shelves) 4. space between the b'fast bar and 'fridge should be at least 90cm but if you choose a wide b'fast bar and a big 'fridge a bigger space is preferable (stand a couple of chairs 90cm in front of your current fridge for a few days and see how it feels) direction of fridge door opening is also critical, first for the cooks and then everyone else: if the size of the b'fast bar can be enlarged or reduced with overhanging counter then a change of walkway is not so difficult 5. as suggested by girlguide, the cooktop and rangehood might be better on the outside wall for ventilation 6. there seems to be a lot of small cabinets and drawers in your plan and there could be some better (and cheaper) combinations but when i tried to access IKEA kitchen planner to confirm available sizes it's not responding today 7. i've attached my suggested approximate base cabinet sizes: starting with corners and work outwards, aiming for the biggest standard carcases and then add drawers to suit purpose ..

Looks superb, kudos to you and the designer, builder it sure now looks classy and great use of space.
