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:

You are considering installing a rooftop pool, right? I don't have one, but I did pull up this link for you -- it has some good information: http://outerspacesinc.wordpress.com/2010/01/07/on-roof-top-swimming-pool-construction/

It sounds like you need to hire a professional Urban / Land planning firm. Look up UDP International. They are located in Hong Kong, but they do work in India and are originally from India. Good luck......... www.udpcltd.com
