Hey Sudha ji , I'v a few ideas on the placement , a bed takes 9'x6'3'' so place it on the 15' Wall(you can reduce the width by removing side drawers,then you get 3' extra for bigger wardrobes on both sides) with one wardrobe on each side one for him and one for yourself and a chest of Drawers to keep other stuff handy and two Ottomans or love seat in front of the bed so you have enough space in front of the bed for traffic as well,and on the front wall to the bed place your Wall hung T.V, PLEASE keep the colours light , use white marsh by Asian Paints or Honey dew , here are some pics .

I like second plan! That space will fit the wardrobe perfectly. Take all colors from the art. The colors can be lighter or darker than the colors you see in art. Take "Venice" with you to paint store and they might be able to help you choose good colors. Idea: paint four walls the same and see if you like that. If you feel the room lacks interest, then paint the accent wall. Choose a pale green that harmonizes with "Venice" and a darker green accent. Yellow + red accent White + blue accent

Thanks tipi, Now I got the idea. I will post some samples as soon as I make it. If u don't mind , please email your detail to me bobbypeter@gmail.com

My first suggestion would be to change the layout of the room at bit. this is my suggestion:i also think that you should paint the room in a uniform light colour (preferable white) and also paint the wardrobe in the same colour so it doesn't overpower the entrance and blend in with the room. my second most important suggestion is to increase storage. here are some ideas for that: simple plank shelves with filing boxes and folders with labels can be a cheap and efficient way of storage of study material. here are some links for such folders and boxes: https://www.amazon.in/Elan-Bookshelf-Executive-Certificates-Certificate/dp/B00HWRHKOS/ref=pd_sbs_79_11?_encoding=UTF8&psc=1&refRID=BQE8PBQNYQYXHHDEBAVQ https://www.amazon.in/Corpac-Multipurpose-Durable-Plastic-Storage/dp/B01GBBHT1E/ref=pd_sbs_229_40?_encoding=UTF8&psc=1&refRID=1CC92M79MCJDPWBD53H9 https://www.amazon.in/Aristo-Basket-Medium-Without-Multi/dp/B06WGR811H/ref=pd_sim_229_4?_encoding=UTF8&psc=1&refRID=JD75V1WW64930CV4NG69 Also the sunlight is the biggest asset of the room and yet the aluminium window is an eyesore. so i would suggest some nuetral shade curtains. and you can play with the colors of the room with the bedsheets. And agree with studio chippan's suggestion of a painting or a family portrait or frame certificates of the kids achievements. Best of Luck, Purva Saksena (Architect)
