I have the same decision to make and have narrowed it down to wood effect tiles or wood effect LVT (eg Karndean). The benefits of LVT are 1) it is warm underfoot (we will have underfloor heating but don't want to have to have it on all the time), 2) softer to walk/fall on and 3) it doesn't have grout lines to get grubby. This is a big pro for me as our current kitchen grout gets dirty so quickly. The benefits of tiles are 1) they won't fade in the sun unlike LVT (we are s facing) 2) they can come in bigger planks than LVT so fewer joins and a less "busy" effect and 3) I think they look more realistic, ie more like real wood, but this is subjective. Also 4) they may be more hardwearing depending on which LVT you choose. Good luck with your decision!

Hi beano Do you mean on this photo the top of middle ? I will after reading your reply get a full size you’re absolutely right. I’m so surprised no one thinks a contrast is best ? I thought that was number one design rule - but then I’m not an Interior designer .... thanks

Ideally I wouldn’t have guests walking through the utility to use the loo and I think you’ll find doing laundry would be easier having a door from the hall. However in option 2, 1m is very tight as the loo would need to go on the long wall, could you not pinch some space from the utility?

Personally I would go for the second plan. Removing the wall between the kitchen and rear sitting room should give you the space you want and - in my opinion if you are thinking of having a family - a completely separate sitting room. You also have access to the kitchen from the front door without having to go through the sitting room.
