if you are to install a whole new kitchen youl should go all in on what you like. I think combinding a modern kitchen with more old, classic rustick asscesorise/Udecor, would look great. I think a soft brown modern kitchen would look great with the floors you have. a black kitchen would also look great, no matter what i would chose a light counter top. Iwould not place the frige on the right next to the chimny/stove. I. would install cabinets and shelves. I would add a backsplash inside the chimney.

We are doing a new kitchen with antique white shaker cupboards & drawers and I'm thinking a painted, pressed metal splashback behind a free standing 90cm heritage style electric cooker and the subway tiles elsewhere. We are doing an oiled natural shaped huon pine slab for the main benchtop.

I have floor boards in bathrooms. Second house that I've had this with no problems at all n first house and one minor DIY fixed water mark near skirting in second (due to kids). I would always aim for wood throughout but I think there are regulations that make this difficult in new builds.

Base on your requirements, this plan would work and requires the least amount of structural alteration. It actually gives you a decent size kitchen. I have to say that oklouiese's plan is more common in new houses and is preferred by a lot of people. That said, new builds usually have a second lounge upstairs. If your measurements are correct, the kitchen against the back wall where the cooktop and fridge is going to be is 4079mm. Assuming you'll have a double door fridge, and a 600mm wide pantry. you still have decent bench space on each side of the cooktop. Assuming you need 1m walk way between each bench. Your island will be 2480mm x 1200mm which is PLENTY. (1.2m walk way is recommended but it comes down to personal preference and what is the most important to you.) Since the family room is not huge. If you want to use the laundry as extra pantry space it's really not that difficult to get to.
