Rowe Furniture has very clean line sofas that I think would be an appropriate scale for this room. LOVE the red feature wall. You do need to bring the red into the room but knowing how you want the room to feel can help determine a color palette. If you want the room to have energy and "pop", try a split-complementary or triadic color scheme. If you want it to be more relaxed and harmonious, I would suggest an analogous color scheme.

I think your inclination toward rustic and distressed pieces is the right way to go. Consider a movable coffee table - I see 2 recliners that may necessitate some table shifting?- an area rug large enough to incorporate all the seating, rather than just a hearth rug, and enclosed storage for your electronics. If you can post shots of the room, other Houzers may have some more ideas.

How about starting out with a piece of beautiful Indian textile work as an inspiration for your space, or recycled sari fabric, or similar. With your very bright light, you can go a lot more saturated than more northern climates.

Not completely......the side sofa can extend till the centre of two doors and then the lower table comes, still allowing a generous space of one side sliding door opening to outwards....the doors can slide anyways which is majorly for viewing purpose and do you really need that large excess to opening...i was just curious....the glass door looks like 5 feet so you will be left with 3 feet of opening that is equal to any generous door size.....is there any major use of balcony except for vegetation and small gatherings which could still happen with the 3 feet opening........
