Mustafa, my apologies for the delayed response! I've been thinking about your dilemma and this is what I've come up with. I'd make the most of the vertical space in the room so that you allow yourself maximum square footage for counter work space. If you're able to, I would suggest putting the refrigerator on the opposite wall (where the tall storage unit is in the sketch). Something similar to this:

Tsilanko, I would always recommend professional installation where needed. But what I am doing here is suggesting that WHEN you are planning to build or renovate, to consider how your plans will affect you in 20 or 30 years time. Split levels are very hep when you are young. A kitchen 3 steps down at 30 is rarely a problem, but might be a hazard at 60, or, as Marjie1059 suggested, if you break a leg. ... All my parents' homes were terrible for old people. They were forced to move to a bungalow in extreme old sge because the location and design of their home was more suitable for an active young couple with a large family than for an elderly couple with stroke disabilities. I would not want to move again, so my present home has features built in that make ageing in place simpler. Mostly small changes, like grab rails, and lever handles on doors and faucets. A major disability suddenly suffered requires major changes if permanent. I did look at this because it came up in the discussion, but if you look at the heading, Planning for Disability, it means just that. Plan ahead so you don't have to make expensive changes later on. But thank you for your advice, yes, major changes are not in the DIY domain.

Wonder, It will be better if the current space between the two rooms is converted to a bedroom. The existing smaller bedroom could be a dining area with kitchen. Thanks, Nitin Cornerstone Designs, Bangalore.

You should ideally use multi utility furniture. A TV unit with in built or foldable dining table. Use big mirrors and light colors to give a spacious look. Because you have a big window ( in the living room) . That can be the accent wall with some dramatic curtains and a corner drop light. There is alot we can achieve in this space. This space seems to be quite exciting to design !
