Hi Dr. Retro, Thanks for your reply . We are very happy for our home and can’t wait to move in. At the moment, it’s just an empty shell and we will buy furniture piece by piece to fill up the house slowly.x I have been learning a lot about home decor and furniture arrangement from the internet lately! Can you comment on my floor plan in the picture? Is this how you would put the corner lounge in the living room?

The photo has couch located to make room look big rather than for function, I would try something like this sketch.

The present layout sort of works , but the fact you sort of have a hallway through the middle is fairly inefficient . I suspect I'd put your TV on a cabinet , just in front of the sunroom wall . Why I say that is because my gut feeling is most noise will transfer through ( or under or around ) the glass doors , not the wall itself . If you have the TV over the other side of the room ( the wall closest the front door etc ) the sound may even carry directly across the room , whereas 'pointing back' from that wall may actually get less transference . That means you can use the whole lounge , people can walk through , but around furniture if need be -- a couple of chairs along what is presently the 'hall' if needed/desired , for example . If there is still too much noise ( remember not all BNB guests are mute mouses too ! ) , depending on how often it gets used and whether you also use it too , you might have to consider removing the doors , and framing and walling the cavity .

an island in the kitchen would challenge the available walk through to the family room and the precise space available in the alcove depends on wall thickness so my suggestion has a new location for fridge, wall oven and tall storage, similar location for stove, sink and dishwasher and the alcove used as pantry space with a free standing table rather than an island to test how it feels before committing to a fixed island and a new kitchen and widening the dining room door should not need a DA but always best to ask the building inspector at your local Council
