I agree with everything said so far. Would suggest you get built in book shelvers on both sides of fireplace, lift tv into a slot it fits perfectly into (make sure you have power on both sides). Then it will disappear more rather than fight with fireplace as focal point. I am always disappointed with mirrors over fireplaces, they become dark, are to high to reflect much. Plus then you have three rectangles fighting for center stage. I'd say very colorful artwork instead. Wonder if you can reorient tv where the big chairs are so both tv and fireplace are addressed? Color, maybe you should decide on furniture first?

Oh wow! Thanks everyone... So so much... I would never have seen some of the things that you have pinpointed. I have already got the cabinet and under cabinet lighting, it was turned off when I took the earlier shots. I totally get the suggestion to remove the cabinets etc near the window but would prefer not too just yet... I am back pocketing that for next year! I will add some items on top of the cabinets, and the artwork that you suggested too in the meantime. The window seat I had in mind was for the living room area, instead of the two seater. Would that look better than the two piece, with colourful cushions, and if so should I add a built I cabinet for the tv (right beside it) in the same painted wood colour as the window seat? Also should I put curtains either side of the window seat if I opt to go with that, or stick just with colourful roman blinds? I will look into fixtures for lights and have already started the fabric hunt for curtains/roman blinds/ cushions etc. Also, what colour would you recommend to accessorise the room with?

I really like the clean lines of your kitchen , it's beautiful and I would not add to much colour but you could use some accessories with green and white that would compliment this minimalistic kitchen. For example adding a bright green plant/s or an accessory the same colour as the clock on your top wall can put everything in a nice perspective!

I think something like these tiles from Tile Style (http://tilestyle.ie/all-tiles/tiles/alchimia.html) could look really fresh or perhaps the herringbone tiles? Not sure where you can source these though but I love them. Good Luck!
