The chair will be in kitchen not in living room...

Any photo you could share? Which dimension is the width of the unit? If it is 150mm wide, i dont think i would go any wider with the tiles.

The amended plan isn't too bad. These are my non-professional thoughts: - do you need a mud room? Does it need to be on view to everyone who visits the house? - the main bedroom WIR and bathroom looks like it needs work. The WIR is huge. The bathroom is also big, but the toilet is positioned near one of the two sinks instead of being in a separate room for visual and acoustic privacy (not to mention certain ... scents). Since you have a bath in the main bathroom, I would at least get rid of the bath to give the toilet its own "room" in the ensuite. But, I think the whole area could be re-done to much more efficiently use the space. - the hallway is LONG and dull and only offers glimpses of part of the kitchen. If it can't be changed, consider adding some wall niches for art, sky lights and other features to give it some interest. - I'm not sure why a three bedroom house requires two living rooms and a study. If the study is meant to be a fourth bedroom, then it should have a regular hinged door and a BIR. - the wall between the main bathroom and the living area will need to be soundproofed to the maximum extent possible. At the very least, I would swap the position of the toilet and the wet room in the main bathroom so that guests don't have to worry about what sound is filtering into the living room. - the kitchen is pretty huge. I can't quite tell what appliances have been placed where on the plans, but consider ease of movement between the fridge, stove and sink and whether the current locations will be practical. The space beside the pantry also appears to be pretty useless. I'd consider just expanding the pantry or reducing the size of the pantry and including a built-in desk / bookshelves / charging station beside the pantry.\ Good luck!

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 ..
