I am trying to decide whether to move my kitchen to the back of my house or keep it at the front snd just update it. Hoping for some opinions!

First pic shows my current floorplan. The wall between the living and dining room is no longer there so all currently one big open space. This is a problem because if I have guests we have nowhere to go away from the kids making noise in the living room. The ’sitting room’ is currently a sort of study/ridiculously hot in summer waste of space.

I need to redo that room’s roof with some insulation (currently has none) and upgrade windows (its a very old single storey extension). I plan to change the side door/window into just a window, and change the end window into slightly narrower garden doors. This will make the space more practical and useful.

First plan shows kitchen moved to back room. Main advantage would be lovely views (I back onto a park at the top of a hill), direct access to garden, more open to dining area. Study would move to front of house, reopening a previous door to entrance hall and leaving washing machine and dryer in there so it is totally separate to the main living area. There would be lots of storage in the new study.

Main disadvantages would be i worry the study might become a dunping ground, and it wouldnt be a nice place to sit with a guest. The kitchen would be totally open to living room noise, and would have less storage space and less worktop space.

I worry that moving the sink so far would be problematic. One plumber has told me it would be impossible without digging a new drain down the side passage and making a new connection to the main drain. Another has told me it could be routed bia the space under the floors (suspended timber with void below) but the joists run from side to side, not front to back so I dont know if that would work.

Also, I have a full height fridge which I could not manage without and placing it would be tricky.

The last plan shows redoing the kitchen in the same room it is now in. I would turn the current side door into a window so that I could get a full run of cabinets down that side. The washer and dryer would be stacked in a high cupboard next to the door, and the full height fridge next to it, and wall cupboards on that side of the room only to make it feel more open and maximise light. I would take away the cabinets under the window to remove the awkward corner cupboards, and have some slimline bar stools next to the window ledge for a cooks perch/coffee spot. It is at the front, but i live in a cul de sac, snd have made a lovely garden in front of the window so its quite a pleasant view. There would be more storage and worktop in the kitchen, and i wouldnt have to move the water supply/drainage. I could put a pocket door on the kitchen to limit sounds between there and living room.

I would have a desk further away from the direct sun in the back room, and comfy seating along the other wall so that it would be a nice place to sit with guests with the views, away from the kids, and I would put in some kind of glass doors so that it can be a proper separate room but can also be open.

Disadvantages would be less storage in the study/sitting room, laundry would still need to be in the kitchen which annoys me.

Thats very long. If anyone has made it to the end and has any thoughts Id love to hear them.
