This is an okay layout given all the door / window openings in the room.

Thanks everyone, I'm planning to get my floor tiled up soon, and then later the whitewash. So before all that, I wanna do away with the construction part, if required to transform this hideous corner. I had the roller blinds in my mind to hide these iron windows, but I will also look at options for changing them windows entirely if budgets allow. I might have to use some false ceiling work as well. Posters, I don't think can find space here, but a lounger sofa-bed is a surething with some nice lights. Please do share some pictures of the lights and loungers and floor tiles if you may, for suggestion. I'll be obliged. Thanks again!

Ardhendu, It depends on the overall size of the property and also the location. 12x12 could be ok as the guest room but it may be called smaller when it's a master bed room. Thanks, Nitin Cornerstone Designs, Bangalore.

Hi Farooq, you should go for wall paneling on that wall with a concealed door. The wardrobe can be a part of the unit in front.
