We have four farmhouse style sinks in two different houses, and all present the same problem. It doesn't have anything to do with the material as two sinks are concrete, one stainless steel, and one composite stone. With the two kitchen sinks it's very frustrating spraying out the food particles from corner to corner. Food particles go from one side to the other, and it's very difficult to corral them to the drain. The two concrete bathroom sinks don't have enough slope, so when shaving and brushing teeth, the water and material flow to the opposite side of the sink. It's annoying to wash a 3' wide sink every time it's used. And gross if the sink isn't cleaned from side to side after every use. As a compromise, we're installing a farmhouse concrete bathroom sink with two drains and more slope. As I evaluate many things in life, a, farmhouse sink is a solutions looking for problem.

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 ..

i think it is beautiful but the main thing is to note that you dont want all the amazing materials to fight. I would stick with a white modern farmhouse as it goes back with shaker styling. Honestly people love dark sinks or copper but they usually hate it within 18 months

@siriuskey not related to this thread per se but I believe all cabinetry with the exception of timber comes with white laminate inside (unless you order custom and pay for the inside to be painted). We just had black cabinetry installed in our lounge and the back of the doors are white. I was shocked so contacted everyone I know with new kitchens in dark colours and they ALL had polyurethane cabinets with white laminate on the back of dark/coloured doors.
