We would need to know what is your style? Color and fabric preferences? What will the second bedroom be used for? Pictures of what you already have (and want to keep) would be most helpful, as well as pictures of the flat.

Do you have any photos you can share? We do better with both floor plan and pix. I think the 9' area should be devoted to a library/reading nook with bookcases on the two walls and a comfy chair and floor lamp for reading. I see lots of doors but no windows in your space. The stretch of space from the entry to the balcony/gallery should be kept open for traffic flow, so Place the FP on the 7.5' wall to be seen upon entering. I think 'd try a sectional with two equal wings. Put the TV on the 7' wall between the two doors and float the sofa so one wing faces the FP and the other the TV. Use a credenza 25% wider than the TV rather than a TV stand. In the jog that has a 6' and a 4' wall, try a family game or chess table and stools. Be sure to get a big coffee table made of reclaimed wood so people can put their feet up on it.

@sooz001 - Top frame weather shade is same as bottom one. Attaching new pic for better view. Mostly, i will have to use wooden shutters and extend the weather-shade, may be using some stone or RCC.

Hi Gourango, Keeping it under the lintel level will be convenient for maintenance without using stools or any other equipments. Also, psychologically it would be a dungeon like feeling in case if it's above the lintel level. However, if you have any plans of using the wall for hanging a mirror or something under the ventilator and if maintenance is not that inconvenient for you, you can definitely place it above the lintel.
