What an amazing forum this is. Do hope you have a clearer picture by now. I adore your splashback, it must not be relegated to a utility room. Buy more of the same for that! Perhaps you could frame an extra piece as art in another area. I've painted my kitchen cupboards in 'Hebridean Mist' which goes so well with the slate floor tiles, then a pink fridge freezer and pink edged worktop tiles tie in well. I like to add a little bit of matching colour from one room to another room, moving through the house like that. It givers synergy to all my rooms, none of which are the same colour, but all of which have a hint of another room. Anthology is a fabulous site to look at for lighting. Wayfair has a gorgeous orange glass globe light I want badly! I actually adore the combination of orange, shades of grey, white and black. A simple thing like 1 Cygnus Papilios cushion by Alex Goode can pass one colour into another room.

Hello Colourwise Design, Thought I would give you a visual of what I had meant. I have used Jonathan's drawing as I use sketchup personally for spatial drawings in 3D. However this means you get to see the same kind of view though with his design and scale. Also offers me the chance to show you how the materials can effect the overall appearance as I have deliberately chosen a material colour to blend with the flooring (or as close to so you can see what is solid) which can be done in a myriad of ways so things appear less solid and thus give a more open room configuration ... Have copied Jonathan's chairs which I have slid under a little more. So you have flow and a very simple configuration which does not hinder the exit to the garden which I think you will want to retain personally. So it could be that the first section houses sink, dishwasher. FF could be in left corner where room opens out? Hob could be at dining end. So cook and serve idea. This also allows for the additional room where the area widens. You still have flow between task oriented routes ie sink to ff and ff to hob etc. Making use of height with a single width double ff and perhaps considering a wall oven and some wall hung cupboards on that wall to the right of the image. The dresser might be able to situate to the right of the window on the left of the image. Down draft on hob or overhead extraction and ceiling hung pans or a section underneath hob for pans etc.. So this idea could either be solid with build in cupboards which I would propose have sliding doors or at dining end taper off into a table top.. Its a quick rework to show you what I had envisioned as I saw it. Re the door in to kitchen, perhaps consider a door that is sliding for example a pocket door. : ))

Out of all the ones you’ve listed I like the one from Perch and Parrow but I’m confused when you say footprint within 48x48cm and this one is listed as 42x42cm. Incidentally I found them cheaper here: https://www.costco.co.uk/Furniture-Home/Dining-Room-Furniture/Chairs-Bar-Stools/Gallery-Palmer-Brown-Faux-Leather-Bar-Stool-2-Pack/p/263151 Also found this one: https://www.wayfair.co.uk/furniture/pdp/selsey-living-hoker-65cm-bar-stool-tcdv2652.html?piid= And a bit of a wild card but the cantilever might make it extra comfy: https://www.argos.co.uk/product/8835576 Also have a browse in the Houzz shop. They have lots of barstools so you may find something there.

I have these ones, they are good quality and very comfortable even though they don't look it as they are not 'padded', lots of colour options - https://www.atlanticshopping.co.uk/bar-stools/drift-oak-and-white-bar-stool.html I know they are not swivel but I find swivel stools very annoying and I specifically avoided swivel ones for my 8 and 11 year old as I imagined they would be constantly swivelling around in them which would drive me nuts. They have a good height on the back too which I like and you can lean back comfortably. I've just come across these, which go with your armchairs if you're looking for a match... https://www.atlanticshopping.co.uk/bar-stools/drift-oak-and-blue-velvet-stool.html re: kids dragging stools with legs will be no different to them dragging dining chairs with legs :-), they're unlikely pick the chair up and place it down nicely when moving, I noticed that even adults don't do that :-).
