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.

I love what you've done so far - I would, however, change the light frame to a black one and add matting that is the same colour as the red in your hallway print that will tie your hall way and dining area together in a subtle way as well as making the print bigger - you could take the matt out by upto 15cm (more if you're brave) and the frame width of between 2cm up to 10 (again depending on how brave you are). As it's a rather large wall you can go bigger with the matt and frame as your wall can take it and you've been restrained with the rest of your colour and material pallet. Your plants are lovely but they're lost down on the floor in the corner - if you can boost them up (I've found pots turned upside down work and have also been known to use old pottery sewer pipes painted - they're totally clean of course!) so that they're a feature rather than an afterthought.

OK peeps here are a couple of pics of the new rug. Can you believe I went with my original choice. It's difficult to represent this room and the rug in pics, colours rarely look true and room always look elongated. This rug is 3 metres long and 2.5 mtrs wide but it doesn't look it. Very happy with my choice and thanks again for your help.

Thank you Julie and Kate. Really helpful advice there. @Julie Herbert - Should the rug cover about half the area approx. I also love the lamp in your first pic. @Kate - yes, the tv is a bit small (and old too!). Its on my plan to upgrade. Checking with both of you if a persian rug in beige or lighter shades look good with the setup?
