Room arrangements

[Maximinimalist]

Hi I hope you all can help.

I’m looking for advice on how to make use of the space in the attached. Specifically the space marked 2100mm and extension.

I am thinking of putting the “formal” dining table and chairs in the 2100mm area (it is 2100mm at its narrowest). The extension is 9700x3700 and I’m thinking of putting the kitchen and an island in the end closest to the would-be dining area plus a sitting area to the far end.

The swiggly lines are glass.

My worry is that we would need to walk through the dining area to get to the kitchen and the dining area would be tight with a table and chairs - 2100mm at the narrowest doesn’t give much clearance.

We can’t afford to tear down any load bearing walls.

Any ideas on whether this is the best place for a formal dining area and if not a formal dining area, then what could this room be best used for?

As you have a separate living room, and that 2100 area is partly enclosed by a wall I would not be so keen on using it for a dining area as it will be a relatively high traffic space and could feel a bit dark?
I would probably put the dining area where you say you want to have the sitting area in the extension and then maybe use the 2100 area as a snug/reading nook.

I would put the kitchen in the 2100 area, stretching across to the wall on the left and extending down that wall to the windows at the end of the extension. Don't have an island, have a peninsula built around the load bearing wall and window to the extension (but take the glass out so you can talk though/pass things across).

Have the dining area to the left of the extension, nearest the run of kitchen units, and the seating area to the right.

The reason for this is that the 2100 area will feel cramped with a table and walking through/around it with the shopping will be annoying. If it's the kitchen, you'll need lots of task lighting anyway, so it won't feel dark, plus it's easy access to the utility, and there won't be any central furniture to block the movement from the hall into the extension.

Then you have a lovely light dining area by the windows, with close to the kitchen (both the side run, and the pass through if you do take the glass out of the internal window by the load bearing wall) for easy serving/clearing, and the seating area tucked into the corner away from the kitchen so quieter, with no need to walk through it with food to get to the table when eating. It's also practical when the glass doors are open from the lounge if you have a lot of guests - it becomes one big seating area. I'd consider having blinds/shutters on those doors, though, so you can feel properly closed off in either space if you want to.

One other suggestion: consider making the door between the hallway and the 2100 area a pocket sliding one. This is for a few reasons: 1) it won't get in the way when you are moving around the kitchen - nothing can be tucked away behind the door and 2) you can mostly leave it open, then you will get a view from the front door, through to the extension and (I assume!) the garden, which will be really lovely.
