MyQS

Thank you all for your advise! Much appreciated!

It is a corner plot so access down the side isn't an issue, so either of the ideas you have pointed out will work, probably try to disguise the pipe within the plinth paint/render. The below plan is directly above the kitchen and the boiler sits within the kitchen to the left of the sink (as you look on plan). This would probably be best moving also into the new kitchen area I think. The toilet above would suggest I can tap supplies down?

Thanks for you quick response! The property isn't bought yet, so trying to establish a likely scenario of what the works would entail. The diagram below shows the existing kitchen sink within the kitchen and the proposed I have dropped in to room adjacent. The waste currently shows coming directly out from under the window of where the sink is currently positioned. The wall between the kitchen and the lounge will remain; could the supply run through the ceiling void. between the joists and drop into position. or ran around the walls and cored through the separating wall? And the waste, could that just be cored through the external wall and then tapped into an existing drain? Appreciate your help on this!

Afternoon all... very vague open ended question, but what plumbing works should i expect if I were to relocate my kitchen to the next room and in doing so moving my kitchen sink, dishwasher, washing machine etc.
