Hi Jayrees, I totally agree with what Kat had to offer, I would suggest a non geometric pattern on the rug as the floor is already geometric, a light colour and subtle pattern if you prefer a pattern. The mirror should definitely be moved and I would consider a large light print to compliment the new rug and and drapes. It's a pity that the window screen blocks the view (it's a nice view) but the heavy screen is a necessity these days, I would remove the stickers from the glass to help with the openness. Just noticed that you have an air con in the room so you may be able to remove the screen.

I suggest printing off your plan and drawing your furniture on to scale. Allowing for at least a metre between things like the island and table, sofa etc , it will be hard to fit everything in. The room has a lot of doorways etc that need access space. You could perhaps have the dining table in front of the island and then a couch facing the island but is this enough seating? The other thing to consider is what dining seats you have and how much space they take up, both in and out from the table.

first store the dead animals the out of sight and consider Antique USA (white with a grey base) for all the painted walls, plain ceiling white for the plaster ceilings, white semi gloss for all the painted architraves and skirting boards and keep the timber ceilings and timber doors but replace the floral door knobs with plain satin chrome and use simple flat white and satin chrome ceiling fixtures in all the low ceilings and simple pendants in the high ceilings (good variety of both available in major hardware stores) and it would be worthwhile to replace the patterned row of tiles with plain white ( a textured white tile if you can't match the colour) and clean the blockwork walls and the floors look good

Wow, what a beautiful transformation. Doesn't even look like the same kitchen or house. Great job! Love the extension into back yard. The outdoor space will be wonderful.
