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.

You should better go for a natural garden instead of an artificial one!! You really have a very good space to work on ! U can have a mdf wall panel (jaali work) like around 4'x8' installed on the main wall, lit artificially from the rear side. Then a row of planters sown at a ht of 2'.. then a l-shaped seater across it!
