I would suggest playing around with your zones, move them without hesitation then sit in each space and rule them out or in as you go. Fresh eyes and all that. I would move your dining to your current lounge, the lounge int that alcove where your study is, you window is higher in here and will accommodate that smart fabric sofa with the tv cabinet on the opposite wall, the armchair will fill the corner really well with a smart floor lamp to accentuate the window and views by night, it will easily become a cool place to retreat. Lounges are also nicer when they have some sense of detachment from the busy work zones ie kitchens and hallways. Your study can be modernized and positioned where your current dining table is, because it's small, and would be an afterthought as you walk right past it from the corridor entering this space. Think stunning bookshelves. Some retro looks have floor to ceiling open backed shelves that could create a hall divider when coming in, so the kitchen is a little more separated, but also, the wall could have some smart practical joinery built here. I would put a desk along the short wall with a designer chair, maybe an upholstered one, a featherston or eames. This creative space could really sharpen the overall look in here, there are some amazing looking workspaces to be inspired by, and the new lounge would feel a real getaway tucked into your corner. You simply go there to relax and Wong have people walking through or past you anymore. The dining room will be where it naturally floes towards, although I love your furniture, id consider some eames or tolix replica chairs with this table as well.

If you already have a long house you could try the following by firstly adding the large Pavillion from the middle using windows and doors for walls and adding smaller outdoor Pavillions with decks either side of this cheers

I searched coastal living here on Houzz and Pintrest. Pintrest had probably more suitable pics. Lovely ideas to choose from.

Hi Anna, Definitely could tie in the piano with the ‘pink ‘ theme, you could throw a fur over seat or add a luxe stool to blend in piano with your new look, a large floor rug could tie your furniture placement or no rug at all , love the couch and chair in this photo, a chaise with a feature chair could look gorgeous also adding a little bit of metallic to the room would look beautiful like that coffee table with the blush chairs...gorgeous
