Just to clarify, you have presented 3 versions. I believe the consensus is the original version with the wood grain ( linen grain) cabinetry works the best and is most updated. The only thing that is out of place are the cabinets or "shelves" on both sides of the range hood. If this is what you need to find a solution too. I would suggest only experimenting with rendering options for these two cabinets( or shelves). This cabinet ties in all the other hard surfaces. The white is not working. It just adds another element. The black is a little dated.

With your original pictures - I agree with larger rug. But I don't agree with comments suggesting the rooms are monochromatic. They are lively indeed. I think you are just missing some accessories! Art work on the empty walls - even just a single large dramatic piece is in order. In the bedroom on the white wall, in the living space behind the sofa, in the greenish bedroom behind the two beds. Those are instant areas where you can improve. But I think your spaces are lovely and well put together. Also I agree with the comment about table lamps - some of those would really add something, and your coffee table looks so empty - maybe just one gorgeous bowl, or stack some books. These rooms are 90% done in my opinions, just need a few finishing touches. Some of my rooms come out like this because the clients are not willing to pay for those last few finish items or feel they can do that part themselves...

Rui, On the contrary, If you look from the left it should align with the base cabinet because they are in same size. Most likely, it will go off by 3/8 of an inch after the dish washer (as it has been wiggled in). It is too small a difference to be noticed by average person because they are at different heights. We are suggesting to change either the cabinet above sink or the single box above right of dishwasher. It will be easier and the filler will be least noticeable above the sink as the shutters are already of a different size. Good news, is that you may have the cabinet boxes already. You can check by placing them starting from the left most wall whether the above suggestion works for you. Thanks, Nitin Cornerstone Designs, Bangalore.

You could utilize the shelf space but I am guessing that's really small. Second, you could get L-Shape brackets and place the oven on that wall as shown, provided there is electric supply and possibility of a plug point. Lastly what's the opposite wall. probably if there is space. Personally, I would place the L shaped brackets and since there is light supply in those shelf cabinets I would try to use those lines to pull up 2.5mm wires and pull it from inside the cabinet next to those shelves, or underneath for an invisible seamless finish.
