Update:- I'm looking at whether we can move the wood burner so we could put the dining area where the lounge is, which would increase the bathroom/utility room inside the house by another 4'4 wide x 7'1 . Also means we don't have to build a side extension just for the extra porch etc thus saving us money! Fingers crossed it can work, but this is the space that we would have to play with to split the bathroom and utility now. I've allowed for more hallway space where it recesses to the right to accommodate coat/shoe storage How would you split this down now? The bathroom would have a nice outside window now so not as dark.

Remove loo and put washing machine here - remove bath and put dryer here-add a worktop over both and under the basin . Add an airer over the basin . That’s probably enough .

A floor plan might help

Thank you Jonathon! lots of food for thought there! i am hoping to keep the utility etc on the left hand side if possible to allow the windows to remain in the open plan living dining but maybe we could do a version of that flipped.
