In your situation I’d hire a kitchen planner because I don’t think your layout works for several reasons. It’s only a few hundred pounds which is peanuts compared to the amount you are spending on all of this work.
If the layout is poor it will annoy you forever. And it’s almost impossible to change later because of the cost - you just won’t do it.
We used this company and he was excellent
www.gvsdesigncompany.com/
But I’m sure there are others out there . We went to him with a similar dilemma to yours - not about flooring but “ we have decided almost everything but we can’t get this last piece of the design to work “.
He changed our whole layout including knocking down a wall into an adjacent room which was underused. He was 100% right, our kitchen works very well.
You need to decide on the kitchen design before you start work as it might affect the position of windows and doors and it will determine where services like draining and plumbing need to run.
We used a company that made the units to our sizes, so we didn’t have to work around set sizes . So if we had a 90cm wide space, we could have a base unit of 90cm, rather than an 80cm standard.
I used this to have base units 10 cm deeper so I can have prep space AND use the back of the worktop for eg a Breadbin or toaster.
And I had wall units taller than usual ( we have high ceilings ) and use the top shelves for things I don’t use often . The taller cupboards look much more in proportion to the room.
The best thing for me was having fewer but much larger ( wider ) units. So I have everything grouped together and I never have to search for anything.
Islands - we don’t walk around our island very much because the main working area is an L shape with the island to one side . So I hardly walk at all compared to my last kitchen which was smaller but badly planned.
Everything is right next to each other in work zones
- sink, bins , dishwashers, crockery and cutlery storage
- Food prep - fridge, knives, all equipment, small sink
- Range and pot and over tray drawers
- Dried / canned/ packet food all in one large pantry cupboard
So I can eg
Stack plates after a meal, scrape food waste into food bin, rinse plates , load dishwasher - all without taking any steps . Then I can unload and put everything away in the same positions.
Or I can take out mugs and spoon, use coffee machine or tea bags / sugar and fill with boiling water tap, all from the same place ( I do have to take a couple of steps to get milk out the fridge).
I can take veg out fridge, get knives and chopping Board, peel and chop, , dispose of waste into food bin and cook - all within 2-3 steps .
I know that sounds like a lot of detail but that’s the actual reality of using a kitchen for most families .
