First of all, I don't think that furniture is comfortable enough to sit and watch TV, so the TV should be remove from that room, the purple wall paper and the purple furniture is too much, you should consider another color for that wall and the furniture against the wall it doesn't look good. What is that room at the end is kind of dark and I cannot appreciate exactly what is the purpose of that room. I'm a firm believer in skylights, we have skylights in the laundry room, kitchen, living room and office, they make a big difference. (if you cannot have skylights (or tube lights) can lights are a great option. There are a lot of great ideas from everyone. I can't wait to see the after photos.

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.

This is a great space to work with. Since you have a good length, you can break the terrace into rooms.. with yew to divide the areas, or tall plants with shallow roots. Grow grass in curves and a pathway to lead visitors through the various rooms. Couple of ideas for garden 'rooms': Bamboo with golden stem or black stem as background, with charpai and 'moda' seating with cushions. A light under the foot of the bamboo, looking up will be alluring. Put up a trellis with fragrant climbers like jasmine and seating underneath on a part of the terrace which gets shade in the evening so you and your friends and family can relax. A dry garden with hardy plants like tall grass and Palm tree, pebbles on the ground to create the look. Plant a small flowering tree in one 'room' Add evocative lighting to create the mood in the evenings. As you can see there are many possibilities. Please ensure the ground is well protected from water seepage etc before you start planting. Also ensure the height of the periphery wall is taller for it to be safe for children and adults. Bear in mind the size of the plant, roots, sun and water needs before you choose your plants. Enjoy the creation..!

Plan the bed on the T.V. wall. You can start from the window side. The sequence will be first the dressing mirror with 2' wide dressing unit then 6' wide bed next 2' wide night stand. By providing the dressing near the widow, you'll have the advantage of natural light. On the opposite wall make a drawer chest or the study beneath the window next is wardrobe. Plan the wardrobe in such a way that you can provide the T.V. unit centering the bed. This way you need not do any structural changes and it fulfills the requirements also. Never compromise with the wardrobe depth. You must provide 24" depth for a perfect wardrobe.
