A narrow, long space like that can feel like a challenge, but if you figure out how you want to use the space before you start designing you will find a lot more success and fewer headaches. Here are some considerations before you start your plan: How much does privacy matter, and not just from neighbors but privacy from the indoors to the outdoors (considering you glass walls and ceilings you’ll need to think about how the space will work from both the inside and the outside). How do you plan to use the space? More specifically, do you plan to host lots of big parties or are you looking for a quiet place to enjoy your morning coffee? Or both? What is the material of your boundary wall? How can you use the wall to enhance the design and functionality of the space? Could you grow a vining plant up the wall for more greenery, or add narrow planters at the base of the wall for a vegetable garden? Do you want any type of covering for the space, like a pergola, roof, umbrella or other sun covering? Do you want it for the full space or just one area? What is your budget? Depending on your goals and timeline for the project, you might have to adjust the rest of the plan (if you don’t have the budget to make your dream space happen, consider taking the project on in phases and slowly save up to make the next phase happen). In the meantime, we’ve created alist of considerations before you start a landscaping project, as well as ideas for pergolas, andpatio lighting ideas. Here are a few images to get your design wheels turning:

I would break it up into various rooms, approximately 10 feet by 15 feet each, though a longer one with a long narrow (2 feet?) water feature against the wall and seating and plants in the center part would work. Plants on the wall, making it vertically green. A path leading from room to room should jog, so you cannot see straight through. Change the theme of rooms, large fancy pottery, an outdoor dining area, sunbathing area if possible.

Hi Farooq, you should go for wall paneling on that wall with a concealed door. The wardrobe can be a part of the unit in front.

Hello, The window looks a little narrow but is placed in a really interesting place . You could go for creating a nice little bay window type here .for this you would need to create a sitting using wooden ply slightly uptil cill level and a foam seat mattress of the size. For dressing the window, roll up curtain could work the best here,I will attach some references.  Further if u wish to decorate it more in Roman style you could opt for a three side frame made around the window opening (On the wall) Shivani Chandra, Architecture Student Alittle
