Are the gates meaning doorways?

Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.

In the empty space between the cabinets you can have such floating shelves to place books or any display items. You can buy them online o even get them made at any carpentry shop. You could have white to keep the uniformity or blue as a contrast to the white cabinets and matching the blue skirting and table top and the wall too. As a DIY you could instead make a french memo board in a a kickass grey or beige and keep your memos, notes, photos and everything else. Hang your earphones and cables from it, keep your guitar plectrums etc. You will find lots of DIY tutorials for this. This could go well in the space between the cabinets as well and gel with the study area.

First thing you need is a pad of graph paper to understand that there is no way the furniture items are to scale (exception could be the dining table) I'm guessing the kitchen is off to the left and the main entry is into the Drawing room? Can the wall be eliminated between the two spaces for more flexibility? - if so, the drawing room space would lend itself perfectly to a round dining table. But the main thing is to draw on graph paper the space & actual dimensions of the furniture you'll be bringing to your new home - so you are not shocked when you move in.
