If it were my kitchen, I'd want to group the different areas together . So
the crockery and cutlery is together, beide the dishwashers and sink
Bins and recycling near sink
Cooking together - hob, oven and microwave
Pan drawers
Large cupboards for cooking dishes , baking stuff, food processor,trays, scales , mixing bowls ,
Large pantry style cupboard for food (I'm not sure a roll up cupboard goes with your shaker style )
I'd have table and chairs at the window at the top
Then a L shaped layout , runninh down the left and across the bottom wall , as that minimises the walking . Wall and base units on left wall, base only on bottom wall , tall units on right hand wall
So roughly ( From top left going down the page )
2 dishwashers
1.5 bowl sink with bins underneath
600 mm drawers
Large base unit ( 1200) for storing baking etc stuff
Above this wall units for storage of crockery . Should be right above your sink and dishwashers, so you can unload and put straight into cupboards above. And next to the table for clearing and setting . Wall storage means less begining - Much easier onthe knees . Plate rack is easy to use and suits the style
Down the rest of that side and across the bottom - cooking area and fridge
Worktop either side of hob
Eye level grill and microwave
Island - now much further down the room and shorter
Oposite sink - recycling bins
Near cooking area - large pan drawers
Top of island is for food prep
Use the narrow cupbaotds round the " wrong " side of the island for occasionally used items
If you really want a sitting area, id just extend the worktop in a curve at the top and use a couple of high stools .
Worktops - I'd use granite on the L and wood on the Island . Granite is good for wet area and cooking area
Right hand wall , from top to bottom - table and chairs at top
Large pantry for food storage - wide but not too deep ( thinsg get lost at the bakc ) . This is an outside wall I think so shoudo be cool. Keep all everyday food in the top and things you use less often on the bottom , like drinks .
Assuming that's an existing chimney and you want to keep it - I'd have a wood burning stove and a narrow hearth/plinth . Then I'd re hang the door so you can't come into the room and trip over it .
The right hand side is the main route down the room , so anyone coming through the room is not in your working L on the left .and away from cooking area and sink .
