I think you should stay with a simple pattern for draperies. Possibly a pattern incorporating the white trim and warm yellow walls. This would be soft and understated and something that you wouldn't get tired of easily. Other colors could be introduced with accessories.

you are thinking about the space right now. it looks odd, no doubt. 1) when you fill in with the furniture, just make sure the three steps are hidden. 2) consider three potted plants of different height, so the rectangle is complete. 3) glass bowl with Siamese fighting fish for each step 4) figurines of different heights 5) 2inch square wooden bar on each step up to the top of the rectangle. and complete the entire rectangle if you want with a smaller rectangle open in the center my suggestion is, there is a reason why this space ended up like this. it will look great once you put something there. things like these are what make your house unique.

that is what i have added if you can see the pic above.. want some suggestions on partition that i can use between dining and sitting

Many thanks for your valuable comments. 1. My intention of raised cabinets was to clean it daily, as cabinets that touch floor accumulate lot of dust and food particles below. If we rule out steel legs, any inputs on raised floor only of cabinet area and then cabinets?(Just like plinth in modular cabinets- but this will be permanent and of tiles) I have not seen such structure anywhere, so curious if it will work. Otherwise I will go with traditional ones. 2. Moving pooja out of kitchen is very difficult as other rooms are just enough for their function. Currently a small Mandir is attached on wall where Fridge is shown in layout. I thought the new area could be little extra for all pooja related things. Will like to know the reason of your recommendation, is it odd in whole design, or not suitable in area .. or anything else? How about moving it to corner of dining area?
