First, the furniture is too traditional for a modern look. I would go for a light, airy look to take advantage of the oodles of natural light. Can go for Scandi designs. Look at Ikea for simple inspirations. Would also suggest changing the curtains for plain blinds or even plain curtains in a heavy fabric. Textured fabric will do quite well here, I suppose.

Sujithra, Please try to evaluate if your current refrigerator would be good enough for you for next 5 years. If yes, then 1-2 inches gap either side shall be fine. But if you foresee any likely change in near future for a bigger refrigerator it will be better if you plan for it now. I think your designer is making a provision for your future needs which IMHO is a good thing. Thanks Amit, Cornerstone Designs, Bangalore.

this is the list of things you can use to make your fridge look more attractive Refrigerator Magnets. Decorative Memo Boards. Shelf Liners. Magnetic Picture Frames. Wall Stickers & Murals. For painting you can look out for hydro dipping or spray pint it

Hi M J, It's always wiser to have as much Natural light and if possible ventilation too, as possible. It's way more essential than conditioned air (Ac). Blocking a window will be a permanent thing, your new layout might change in future with change in your lifestyle / needs. Hope this helps. Cheers, Pavan.
