First of all the images you posted you cant make anything out what you got there. Secondly you should contact a local Architect when doing something like this, not only for structural reasons, but window design as well. He will layout window detail based on the window sizes available from a certain manufacturer or you can take his drawings which indicate opening detail to a place who sells windows, and they have catalogs of window combinations and sizes to make it work with what you have.

Hi Option 1 As suggested by Cornerstone above. This way the TV will be visible from dining too Option 2 Move TV to the corner of the entrance wall, next to the window, placed at 45 degree angle. The L shaped sofa can then go to the diagonally opposite corner. The wall can be a see through book shelf/crockery shelf. This is better as the visitors have some inviting empty space as soon as they walk in instead of a sofa. Option 3 TV in current position, but instead of the TV being mounted on wall, perhaps have an open shelf (like below)

Hi Deepak, Neighboring noises can be annoying, especially night. I would advise the same, go for u-PVC windows, that will help in maximum noise reduction. As I can see in image, a full-length curtain indicating probable full window or door. You should go for u-PVC window/door for that too. The noise will be reduced to a minimum. -Thanks, -Neelam -Lines and Profile

Hi Prayas and Peeyush, Let me tell you that the above images are for reference purpose only and the design can never be replicated to perfection since the site conditions vary for every room, space and project. The above mentioned ideas are for you to figure out what suits the space the best and accordingly customize. Materials like wallpaper, 3D paneling, rafters, veneers, wall cladding etc. come in smaller modules and hence work for almost all wall sizes. It is totally up to you to choose what look you desire and what material you want to go with. No image is ever going to give you the exact feel and aesthetic of the space. If you are finding it difficult to imagine or choose, it is best to involve an expert such as an architect/ interior designer in the process to customize designs for you and achieve desired results.
